摘要:

以对甲苯磺酸和淀粉为原料, 采用一步碳化法制备碳基固体酸催化剂, 并采用正交试验法对碳基固体酸催化餐厨废油酯化反应的最佳工艺条件进行了研究; 在中试规模上以餐厨废油为原料, 以酸碱联用催化的工艺生产制备生物柴油. 结果表明, 酯化反应的最佳工艺条件为反应温度 60 ${^\circ}$C, 反应时间7 h, 催化剂和甲醇用量分别为餐厨废油投入量的4%和30%, 餐厨废油的酸值可降低至1.2 mg KOH/g. 该催化剂具有较好的热稳定性和催化反应活性, 可替代液体酸应用于酸碱联用催化制备生物柴油工艺中, 具有设备成本低、生产效率高、对环境友好的优点.

Abstract:

Optimization of the esterification reaction condition was investigated by orthogonal experiments using carbon-based acid as catalyst prepared by p-toluenesulfonic acid and starch. In a pilot scale study, biodiesels were produced from waste oil in an acid-base cascade process. It was found that the carbon-based solid catalysts displayed high activity under an optimization condition, which was 60 ${^\circ}$C for 7 h, with 30% methanol and 4% catalysts of waste oil. The acid value of waste oil can be reduced to 1.2 mg KOH/g after esterification. It was concluded that the carbon-based solid acid catalysts were proper to be used in biodiesel production from waste oil of acid-base process instead of liquid acid catalysts.

Key words: starch, carbon-based solid acid, catalyst, waste oil, biodiesel
