| Abstract: | Supported solid acid catalyst TSOH/HY-SBA-15(TSOH-modified mesoporous molecular sieve) prepared by impregnation method was used in the transesterification of soybean oil with methanol to prepare biodiesel fuel.The influence factors were investigated.And the optimal conditions were found: a molar ratio of methanol to oil of 25∶1,a catalyst dosage of 5 %,solvent dosage of 30 %,reaction temperature of 180 ℃ and reaction time of 7 h employing(0.5 mol·L-1)TSOH/(10 %)HY-SBA-15 as the catalyst.Under this condition,the yield of biodiesel can reach 94.6%. |
