| 摘 要： | 采用固体酸催化酯交换方法，研究了由麻疯树油制备脂肪酸甲酯(生物柴油)过程中催化剂类型及工艺条件对生物柴油产率和产品组成的影响. 采用沉淀法制得两种固体酸催化剂ZrO2-SO42-和K4Zn4[Fe(CN)6]3，利用XRD, FT-IR, BET和元素分析仪表征了固体酸结构和性质. 以麻疯树油为原料油，分别比较了原料油的酸值及反应温度对2种催化剂的影响，利用气相色谱-质谱联用分析仪分析了产物的组成. 结果表明，ZrO2-SO42-和K4Zn4[Fe(CN)6]3催化高酸值麻疯树油时，ZrO2-SO42-容易失活，甲酯收率降为84%；以Fe-Zn为催化剂，甲酯收率达到93%，使用5次后甲酯收率仍达90%.

| Abstract: | Transesterification of Jatropha curcas oil was carried out in the presence of solid acid, the effects of types of catalysts and reaction conditions on the bio-diesel yields and the components in the process of the preparation of methyl esters (bio-diesel) were examined. Solid acid catalysts ZrO2-SO42- and K4Zn4[Fe(CN)6]3 were prepared with precipitation. Their structures and characteristics identified by XRD, FT-IR, BET and elemental analysis were compared. Their catalytic activities changed with acid value... |
