Cornus wisonian is a woody energy plant unique to the southern region, the fruit oil can be used as the important raw materials in catalytic cracking. This experiment studied the catalytic cracking decarboxylation reaction of Cornus wisoniana oil. Through experiments, CaO / KF made by ourselves was proved to have good catalytic effect, gas production rate is lower than 12.0%, the by-product of the bottom of the kettle residue is controled under 5.0%, the yield of liquid fuel oil products is at 83.0% or more. Because of high acid value, pyrolysis oil can’t be directly burned. In this study, p-toluenesulfonic acid was used as a catalyst for alcohol esterification. Under the Optimization condition, acid value is lower than 1.0 mg KOH/g. Then alcohol esterification was used to reducing acid of cracking bio-fuel products and p-Methylbenzene sulfonic acid as catalyst. After reducing the acid, this kind of fuel is closer than traditional fossil fuels, able to alternative to diesel, and to achieve energy conservation.
