Recently, PhD student Miss Jing-jing Guo supervised by Prof. Zhen Fang<\/strong> published a research article in Renewable Energy about biodiesel production from high acid value oil with liquid lipase.<\/p>\n

Undeveloped Periplaneta americana<\/em> oil (acid value 38.32 mg KOH\/g) was directly used for one-step production of biodiesel with lipase without acid-pretreatment step for the commercial alkaline process. Biodiesel was produced via<\/em> simultaneous esterification and transesterification of Periplaneta americana<\/em> oil in the presence of lipase Eversa\u00ae Transform 2.0 (ET2) (12 US$\/kg) in solvent-free system. The maximum biodiesel yield of 98.63% was obtained under the optimized conditions of 32 \u00b0C, 8.5 wt.% lipase dosage, 8 h, 6.5\/1 methanol\/oil molar ratio, and 4 wt.% water. Lipase ET2 was recycled 6 times at > 89.52 % biodiesel yield. Biodiesel yield of 93.94 % was further achieved in a 1 L reactor with 15.08 g\/kg lipase\/biodiesel. Biodiesel cost was estimated as 589.3 US$\/ton. Kinetics study gave activation energy of 24.50 kJ\/mol with kinetic Michaelis constant of 1.19 mol\/L. The physicochemical properties of biodiesel met both Chinese national and US ASTM standards that could be blended with petro-diesel to be applied in both countries. This study suggests that lipase could directly catalyze waste oils for the production of biodiesel at low temperature.<\/p>\n
