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.

Nahar, Sharifun published the artcileNoninvasive, label-free, and quantitative monitoring of lipase kinetics using terahertz emission technology, Recommanded Product: Methyl octanoate, the main research area is noninvasive quant monitoring lipase kinetics terahertz emission technol; Candida antarctica lipase B; enzyme assay; esterase; horseradish peroxidase; milk; terahertz emission.

Enzymes catalyze chem. transformations of great importance in many fields, and anal. of the rate of these transformations is equally important. The latter are typically monitored using surrogate substrates that produce quantifiable optical signals, owing to limitations associated with “”label-free”” techniques that could be used to monitor the transformation of original substrate mols. In this study, terahertz (THz) emission technol. is used as a noninvasive and label-free technique to monitor the kinetics of lipase-induced hydrolysis of several substrate mols. (including the complex substrate whole cow’s milk) and horseradish peroxidase-catalyzed oxidation of o-phenylenediamine in the presence of H2O2. This technique was found to be quant., and kinetic parameters are compared to those obtained by proton NMR spectroscopy or UV/Vis spectroscopy. This study sets the stage for investigating THz emission technol. as a tool for research and development involving enzymes, and for monitoring industrial processes in the food, cosmetic, detergent, pharmaceutical, and biodiesel sectors.

Naser, Jamil published the artcileRegeneration of spent bleaching earth and conversion of recovered oil to biodiesel, HPLC of Formula: 111-11-5, the main research area is oil biodiesel conversion spent bleaching; Biodiesel; Bleaching; Pyrolysis; Regenerated bleaching earth (RBE); Spent bleaching earth (SBE); Vegetable oil.

A large amount of spent bleaching earth (SBE) solid waste is generated by the vegetable oil refining industry. This spent bleaching earth contains entrapped crude oil and in most cases, it is disposed of in its pristine state, which is considered an environmental hazard. In this work, the regeneration of SBE by pyrolysis or solvent extraction, and the conversion of the recovered entrapped vegetable oil to biodiesel are investigated. The entrapped oil was extracted using n-hexane, methanol or steam as solvents, and the SBE was regenerated by pyrolysis under inert environment of Nitrogen at 450°C, 550°C and 650°C. After oil extraction, the regenerated bleaching earth (RBE) was activated and employed in virgin vegetable oil bleaching. Peroxide activated samples of methanol-extracted and pyrolyzed regenerated bleaching earth at 450°C and 650°C exhibit superior bleaching property; demonstrating that the SBE could be regenerated to have superior bleaching capacity over fresh bleaching earth. Thermogravimetric anal. (TGA) and Fourier transform IR (FTIR) anal. of the SBE show that methanol extracted 23.5% out of the 35% residual oil (i.e. 67% efficiency) compared to 15.7% (i.e. 45% efficiency) by n-hexane, while pyrolysis extracted 33% out of the 35% residual oil (i.e. 95% efficiency). GC-MS anal. of the produced biodiesel shows that the n-hexane extracted oil produces more fatty acid Me esters (FAME). Therefore, the choice of solvent depends on the intended application; as methanol regenerates the SBE better while retaining its adsorptive properties, while n-hexane gives a better biodiesel yield.

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.
