In this study, food waste was mixed with microalgal biomass to regulate the C:N ratio in order to not only promote biodiesel production from lipids through transesterification during the first stage but also bio-crude production from carbohydrates and proteins through hydrothermal liquefaction during the second stage. The cytoplasms of microalgal biomass, which reduces polarity differences between lipids and the methanol reactant, improved transesterification reactions of lipids in food waste, thereby promoting biodiesel production by 13.3%. The optimized Maillard reactions between the carbohydrates and proteins (C:N ratio = 6.2) promoted bio-crude production from the biomass residue by 13.0% after biodiesel extraction The highest weight ratio of biodiesel (with a higher heating value of 41.0 MJ/kg) through the transesterification reaction to dry feedstock (composed of microalgae and food waste with an optimized weight ratio of 1:1) was obtained at 23.2% (weight). GC-MS, FTIR and NMR were applied to analyze the physicochem. properties of bio-crude produced via hydrothermal liquefaction. A high-weight ratio of bio-crude (Higher heating value: 35.1 MJ/kg) to biomass residue after biodiesel extraction was achieved at 15.5% (weight). This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Recommanded Product: Methyl nonadecanoate).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Recommanded Product: Methyl nonadecanoate
