Direct biodiesel production from wet microalgae biomass of Chlorella pyrenoidosa through in situ transesterification.

摘要: A one-step process was applied to directly converting wet oil-bearing microalgae biomass of Chlorella pyrenoidosa containing about 90% water into biodiesel. In order investigate the effects content on biodiesel production, distilled added dried form used produce The results showed that at lower temperature 90°C, had a negative effect production. yield decreased from 91.4% 10.3% as increased 0% 90%. Higher could compensate effect. When reached 150°C, there no effect, and over 100%. Based above research, optimal conditions were investigated. Under 100 mg dry weight equivalent biomass, 4 mL methanol, 8 mL n-hexane, 0.5 M H2SO4, 120°C, 180 min reaction time, high 92.5% FAME 93.2%. suggested be effectively produced this effort may offer benefits energy requirements for
