光皮树是一种主要分布于我国黄河流域以南的木本能源植物，其果实油可以作为催化裂解的重要原料。本文对光皮树油催化脱羧裂解制备生物基富烃燃料进行了研究，通过实验发现自制的负载型催化剂CaO/KF具有较好的催化效果，气相副产物产率低于12.00wt%，釜底残留物控制在5.00wt%以下，液相生物基富烃燃料油得率大于82.00wt%。裂解所得生物基富烃燃料酸值较高，无法直接应用于发动机。本研究采用对甲苯磺酸为催化剂进行醇酯化，优化条件下燃料酸值低于1.00 mg KOH/g。生物基富烃燃料经酯化降酸后性质接近传统0# 柴油，满足替代车用柴油要求，实现节能减排。

Swida wilsoniana tree is a kind of main woody energy plants distributed in the south of the Yellow River basin in China. Its fruit oil can be used as important raw materials in catalytic cracking. This paper studies the catalytic cracking decarboxylation reaction of Swida wilsoniana oil. Experiments show that CaO/KF made by ourselves has good catalytic effect, gas byproduct is lower than 12.00wt%, kettle residue is controlled less than 5.00wt%, the yield of liquid fuel oil products is higher than 82.00wt%. Because of high acid value, pyrolysis oil can’t be directly burned. This research adopts p-toluene sulfonic acid as catalyst for the esterification reaction. Under the optimization condition, acid value is lower than 1.00 mg KOH/g. The acid value of rich hydrocarbon fuels before esterification is too high for the engine to apply directly. After reduced acid value by esterification, the properties of rich hydrocarbon fuels are much closer to the traditional 0# diesel, meet the demand of alternative automotive diesel, achieve the purpose of energy conservation and emissions reduction.
