摘　　要：以四水硫酸锆改性HY-SBA-15(ZS/HY-SBA-15)为催化剂,催化大豆油和甲醇制备生物柴油,考察最佳制备条件。实验结果表明,四水硫酸锆负载量为30%,n(甲醇)∶n(大豆油)=12∶1,m(催化剂)∶m(大豆油)=3%,m(溶剂)∶m(大豆油)=30%,120℃下反应6h,生物柴油的收率可达96.78%。对合成出的生物柴油性能指标进行检测,结果表明其主要性能指标与我国0#柴油相接近。Biodiesel is synthesized using soybean oil and anhydrous methanol as raw materials via ZS/ HY-SBA-15 （zirconium sulfate modified micro-mesoporous composite zeolite） made by impregnation method as catalyst through transesterification. The optimal conditions were found to be a molar ratio of methanol to oil of 12, a catalyst dosage of 3 %, a solvent dosage of 30 %, a reaction temperature of 120 ~C and a reaction time of 6h employing （30%）ZS/（10%）HY-SBA-15 as the catalyst. Under the conditions,the yield of biodiesel may reach 96.78%. The performance of biodiesel obtained was in accordance with that of 0^# diesel.
