摘要

Abstract

Biodiesel produced from crude

Jatropha curcas

L.oil with trace sulfuric acid catalyst(0.02%-0.08% oil) was investigated at 135-184℃.Both esterification and transesterification can be well carried out simultane-ously.Factors affecting the process were investigated

which included the reaction temperature

reaction time

the molar ratio of alcohol to oil

catalyst amount

water content

free fatty acid(FFA) and fatty acid methyl ester(FAME) content.Under the conditions at 165℃

0.06%(by mass) H

of the oil mass

1.6 MPa and 20:1 methanol/oil ratio

the yield of glycerol reached 84.8% in 2 hours.FFA and FAME showed positive effect on the transesterification in certain extent.The water mass content below 1.0% did not show a noticeable effect on trans-esterification.Reaction kinetics in the range of 155℃ to 175℃ was also measured.
