关 键 词：Biodiesel Boettcherisca peregrine Food waste Fermentation residue Swine manure
摘 要：The feedstocks for biodiesel production are predominantly from edible oils and the high cost of the feedstocks prevents its large scale *** this study,we evaluated the oil extracted from Boettcherisca peregrine larvae(BPL) grown on solid organic wastes for biodiesel *** oil contents detected in the BPL converted from swine manure,fermentation residue and the degreased food waste, were 21.7%,19.5%and 31.1%,*** acid value of the oil is 19.02 mg KOH/g requiring a two-step transesteriflcation *** optimized process of 12:1 methanol/oil(mol/mol) with 1.5%H2S04 reacted at 70℃for 120 min resulted in a 90.8%conversion rate of free fatty acid(FFA) by esterification,and a 92.3% conversion rate of triglycerides into esters by alkaline *** of the BPL oil-based biodiesel are within the specifications of ASTM D6751,suggesting that the solid organic waste-grown BPL could be a feasible non-food feedstock for biodiesel production.
