摘要：研究了活性炭负载对甲苯磺酸催化剂的制备方法及其在酸化油制备生物柴油中的应用。运用不同负载方法制得负载量不同的催化剂TsOH/C-A、TsOH/C-B和TsOH/C-C,比较了3种不同的负载方法对5种不同种类活性炭(煤质1#炭、煤质2#炭、煤质3#炭、柠檬酸炭和椰壳炭)催化活性的影响,筛选出活性最高的活性炭类型为柠檬酸炭及最佳负载催化剂为TsOH/C-C。通过正交试验考察了影响酯化率的各种因素,确定了最佳反应条件为:催化剂用量10%,反应温度70℃,醇油物质的量比28∶1,反应时间2h,酯化得率达88.8%。
Preparation and application of biodiesel by esterification of oils of high acid value catalyzed by p-toluenesulfonic acid supported on activated carbon were studied. Catalysts of TsOH/C-A, TsOI-LZC-B and TsOH/C-C of different loading amounts were prepared by different methods. Comparing 3 kinds of supporting method and 5 kinds of activated carbon （ coal-activated carbon 1^#, coal-activated carbon 2^#, coal-activated carbon 3^#, citric-acid-ctivated carbon and coconut-activated carbon）, the best activa- ted carbon was citric-acid-activated carbon and the optimum kind of supported catalyst was TsOH/C-C. Through orthogonal experiment, effects of influencing factors on esterification yield were studied. Under the optimal conditions： amount of catalyst 10 %, reaction temperature 70 ℃, molar ratio of methanol to acidified oil 28 ： 1, reaction time 2 h, yield of the product could reach 88.8 %.
