Al-Gharibeh, Elyasa published the artcileIgnition and combustion characteristics of decanoic acid derived alkyl esters in a fuel ignition tester, COA of Formula: C11H22O2, the main research area is ignition combustion decanoate alkyl ester fuel tester.

This work investigated the combustion characteristics of decanoic acid derived alkyl esters in an ASTM standard Fuel Ignition Tester (FIT), with special emphasis on the influence of carbon number variation for the alkyl moiety within the alkoxy group on the autoignition delay times. The compounds of interest include Me, Et, Pr, and Bu decanoate. Higher carbon numbers lead to an increase in reactivity in terms of the decreased ignition delay times for Me through Pr decanoate. However, there was a small reduction in relative reactivity for Bu decanoate. With increasing air temperature, while the ignition delay times showed a monotonic reduction for all the four fuels, the maximum rate of pressure rise exhibited a non-linear variation. Specifically, the maximum rate of pressure rise was found to increase at of 700-758 K and then decrease within 758-825 K. The post-combustion peak pressures also exhibited a similar trend. This reduction in reactivity with increasing temperature correlates to the neg. temperature coefficient behavior. In addition, all the test fuels show a two-stage ignition response at the lowest oxidizer temperatures investigated. Therefore, the current experiments demonstrate the suitability of the FIT as a research tool that can be used to extract information on fuel reactivity other than the widely studied metric of the derived cetane number

Pereira, F. N. published the artcileObtaining a reduced kinetic mechanism for methyl decanoate using layerless neural networks, Product Details of C11H22O2, the main research area is reduced kinetic methyl decanoate layerless neural network.

Major efforts in the search for techniques for the development of reduced kinetic mechanisms for biodiesel were observed, since these mechanisms may have thousands of species. This paper proposes a reduction strategy and presents the development of a reduced kinetic mechanism for piloted jet diffusion flame of Me decanoate (MD). The strategy consists of applying the DRG, Directed Relation Graph, technique for initial reduction, and the use of Layerless Neural Network (LNN) to define the main chain and obtain a skeletal mechanism. Hence the hypotheses of steady-state and partial equilibrium are applied, and the assumptions are justified by an asymptotic anal. The main advantage of the strategy is to reduce the work required to solve the system of chem. equations by at least two orders of magnitude for MD, since the number of species is decreased in the same order.

Li, Ang published the artcileExperimental and Modeling Study on Autoignition of a Biodiesel/n-Heptane Mixture and Related Surrogate in a Heated Rapid Compression Machine, Quality Control of 110-42-9, the main research area is exptl modeling autoignition biodiesel heptane mixture rapid compression.

In this paper, ignition delay time of two kinds of biodiesel, soybean oil Me ester (SME) and waste cooking oil Me ester (WCOME) blended with n-heptane, were measured in a heated rapid compression machine (RCM). To meet the requirement of measuring high boiling fuels like biodiesel, several modifications were applied in RCM platform, which embodied in global preheating, reactant preparation, and gas dilution Along with these methodologies, ignition delay times of SME30 and WCOME30 (30% biodiesel and 70% n-heptane in volume fraction) were measured at 15 bar, within temperature range of 641-772 K. Both biodiesels exhibited typical two-stage ignition characteristics and pronounced neg. temperature coefficient behaviors. To better investigate the ignition process of biodiesel, novel surrogate fuels have been formulated including Me decanoate, n-hexadecane, Me trans-3-hexenoate, and 1,4-hexadiene, according to Chem. Deconstruction Methodol. Autoignition properties of surrogate and target biodiesel were investigated under the same conditions in RCM and good agreements have been found in point-to-point validation experiments, which verified good performance of quaternary surrogate fuels for biodiesel. Furthermore, kinetic models of biodiesel were proposed on the basis of surrogate fuels, which consisted of 4901 species and 18 669 reactions. The novel model has good predictions in ignition delay times in low-to-intermediate temperature regions measured in RCM, and the kinetic model has great potentials in revelation of autoignition mechanisms and in development of CFD applications in internal combustion engines.

Dalvi, Sanjaykumar published the artcileBiodiesel (fatty acid methyl ester) from Chlorococcalean Chlorella vulgaris by single step in-situ transesterification, Recommanded Product: Methyl decanoate, the main research area is fatty acid methyl ester transesterification algae assessment.

To study the single step in-situ transesterification process for synthesis of fatty acid Me ester (biodiesel) from microalgae biomass Chlorococcalean Chlorella vulgaris. The growth and lipid productivity of an isolated microalgae C. vulgaris were studied under Chu’s 10 modified media under phototrophic cultivation conditions. In-situ transesterification of this dry biomass with methanol in presence of base catalyst at 60° C was carried out to investigate the fatty acid Me ester’s biochem. composition by FTIR & anal. performed using GCMS technique. The cetane number was also calculated The biodiesel fraction from C. vulgaris biomass was found to be 85.58%. The 43.40% lipid fraction was obtained from the biomass of C. vulgaris. In the in-situ transesterification process, the optimal concentration of potassium hydroxide (KOH) and methanol yields an 85.58 percent biodiesel fraction. The presence of lipid compounds and the biochem. composition of fatty acid Me ester were verified with the help of FTIR spectral anal. The gas chromatog.-mass spectrometry anal. explores the fatty acid Me ester profile, which comprises 29.05% and 56.54 percent saturated and unsaturated FAMEs. Through GCMS, the fatty acid Me ester composition of C. vulgaris microalgae species was revealed through six types of fatty acid Me esters, of which 54.95%, 11-octadecenoic acid Me ester, is the dominant one. The cetane number of C. vulgaris biodiesel was determined to be 67.726; this is comparable to diesel fuel according to ASTM-D613, and the presence of a higher fatty acid Me ester composition indicates favorable biofuel qualities.

Dandajeh, Hamisu Adamu published the artcileEffect of equalising ignition delay on combustion and soot emission characteristics of model fuel blends, Application of Methyl decanoate, the main research area is fuel blend equalizing ignition delay combustion soot emission.

This paper examines the effect of equalizing ignition delay in a compression ignition engine. Two sets of tests were conducted, i.e. a set of constant injection timing tests with start of fuel injection at 10° crank angle degree (CAD) before top dead center (BTDC) and a set of constant ignition timing tests while also keeping the 10° CAD BTDC injection and adding ignition improver (2-ethylhexylnitrate-, 2-EHN) to the fuel mixtures Soot particles were characterized using DMS-500 instrument in terms of mass, size, and number The exptl. results showed that adding 2-EHN to the model fuel blends reduced the soot surface area, soot mass concentration and soot mean size. Replacing 20 vol% of a C7-heptane with 20 vol% methyl-decanoate (an oxygenated C11 mol.) did not affect the ignition delay or rate of fuel air premixing, the peak in-cylinder pressure or heat release rates. Toluene addition (0-22.5 vol%) to heptane increased the mean size of the soot particles generated by only 3% while also resulted in a slight increase in the peak cylinder pressure and peak heat release rates. Blending toluene and methyl-decanoate into heptane without adding 2-EHN increased the premix phase fraction by at least 13%. However, by adding 2-EHN (4×10-4-1.5×10-3), the premixed phase fraction decreased by at least 11%.

Zhan, Taotao published the artcileSpeed of Sound and Derivative Properties of Ethyl Laurate from Rayleigh-Brillouin Light-Scattering Spectroscopy, Synthetic Route of 110-42-9, the main research area is ethyl laurate sound velocity Rayleigh Brillouin light scattering.

The exptl. speeds of sound combined with Brillouin frequency shifts of Et laurate at temperatures from 294.97 to 572.89 K along six isobaric lines from 0.1 to 10.0 MPa were measured by Rayleigh-Brillouin light-scattering spectroscopy. The expanded relative uncertainty in the reported speeds of sound in Et laurate is estimated to be 1.3% (coverage factor k = 2 with a confidence level of 0.95). Within the temperature limits of 303.15-383.15 K and at pressures up to 10.0 MPa, the derived thermoacoustic properties of Et laurate including d., specific isobaric heat capacity, isentropic compressibility, isobaric thermal expansivity, isothermal compressibility, the difference in isobaric and isochoric heat capacity, internal pressure, and intermol. free length were studied. Because of the heavily updated data of d. and the speed of sound in the literature, a modified Jacobson’s model for biodiesels was proposed over the temperature range from 293.15 to 343.15 K, which is able to calculate the intermol. free length of Et laurate with higher accuracy compared with Jacobson’s model.

Jindapon, Wayu published the artcileContinuous production of fatty acid methyl esters and high-purity glycerol over a dolomite-derived extrudate catalyst in a countercurrent-flow trickle-bed reactor, Name: Methyl decanoate, the main research area is biodiesel fatty acid methyl ester palm oil transesterification catalyst; calcium magnesium oxide catalyst countercurrent flow trickle bed reactor.

In this work, fatty acid Me esters (FAME), as biodiesel components, were continuously produced via the heterogeneously catalyzed transesterification of palm oil with methanol vapor in a countercurrent-flow trickle-bed reactor. Dolomitic rock was used as natural calcium source in the preparation of the calcium oxide-based extrudate catalyst via a phys. mixing method. Effects of operating parameters on the FAME yield and the two-phase flow behavior were investigated. The reaction system was characterized by a high mass diffusion resistance at gas-liquid-solid interfaces due to the low solubility of methanol in triglycerides and the high viscosity of oil. Mixing palm oil with com. grade Me decanoate, a C10 Me ester (C10 CME), at a 1:1 mass ratio during the start-up period promoted FAME production The FAME yield was enhanced by increasing the operating temperature and the methanol flow rate, while operation at a high oil flow rate severely decreased the FAME yield. The concentration of C10 CME, which acted as an emulsifier, in the catalyst bed was crucial to maintain the FAME production stability. In addition to a high FAME yield (ca. 92.3 wt%), the system provided glycerol, obtained without any washing, at a high purity of 93.6 wt%.

This study was conducted to explore the production of magnesium oxide from raw salt solution using electrochem. precipitation, followed by calcination. Electrochem. precipitation was conducted by electrolysis of the salt solution using nickel rods as cathodes and graphite as anodes. Two sets of salt solutions were prepared: one set without pretreatment and another with BaCl2 pretreatment. The solutions were used to study the effect of salt concentration, potential, and electrolysis time. The representatives of the MgO produced were tested as catalysts for transesterification of coconut oil. The results indicate that optimum mass of precipitate was produced from 400 mg/L salt solution electrolyzed using 8 V for 60 min. Elemental anal. using X-Ray Fluorescence (XRF) revealed the presence of Mg as the main component of the precipitate, confirming the electrochem. conversion of Mg2+ into solid Mg(OH)2. The MgO with the purity of 74.23% and 88.87% was produced from non-pretreated and pretreated salt solution, resp. The transesterification experiments indicate that the yield of 90% and 98% was achieved using the MgO produced from non-pretreated and pretreated salt solution, resp.

Balakrishnan, A. published the artcileExperimental correlation of laminar flame pollutant emission indices with methyl ester fuel degree of unsaturation and equivalence ratio, SDS of cas: 110-42-9, the main research area is methyl ester fuel unsaturation equivalence laminar fame pollutant emission.

Fuel unsaturation has been widely cited as a reason for the increased nitric oxide emissions from compression ignition engines when fueled with Me esters (biodiesels) and their blends with petroleum counterparts. In an earlier study, a parameter called degree of unsaturation (DOU) was established to serve as a common platform across different fuel families (esters/alkanes/aromatics) to quantify the effects of fuel unsaturation, particularly with petroleum/biodiesel blends. DOU can be evaluated based on the average mol. formula of the fuel alone without involving complex and expensive exptl. procedures such as those involved in the measurement of iodine number and bromine number In this article, the fuel unsaturation effects on the emission characteristics from the laminar flames of blends of various pre-vaporized Me esters, such as Me oleate, neat biodiesels (from Me esters of soy, canola, palm and rapeseed feedstock) and biodiesel blends were investigated at four burner-exit equivalence ratios of 0.9, 1.0, 1.2 and 1.5. The selection of these fuels for this study was an attempt to isolate the fuel unsaturation effect of biodiesels, and their blending effect with petroleum fuels. Exptl. correlations were developed between DOU (over a range of 1.7-2.5) and global NO and CO emission indexes as a function of equivalence ratio. The effects of DOU on EINO were significantly influenced by the equivalence ratio, with the maximum influence at an equivalence ratio of 1.2.
