以GaNO₃为改性剂，采用浸渍法对ZSM-5催化剂进行改性。利用XRD、FT-IR、SEM等手段对改性前后催化剂进行表征，并进行催化性能评价。结果表明，使用2-Ga-ZSM-5催化剂进行反应，小桐子油的转化率为37.22%，液体产物酸值为1.67 mg（KOH）/g，皂化值为8.94 mg（KOH）/g；液体产物主要成分为芳香族化合物，质量分数为96.03%。

ZSM-5 catalyst is modified by impregnation method using GaNO₃ as a modifier.Before and after modification,the catalysts are respectively characterized by XRD,FT-IR and SEM,and their catalytic performances are evaluated.The results show that 2-Ga-ZSM-5 catalyst is the best one,over which the conversion of Jatropha curcas oil can reach 37.22%,the acid value of liquid product is 1.67 mgKOH·g^-1 and the saponification value is 8.94 mgKOH·g^-1.The main components of liquid product is an aromatic compound,with a content of 96.03%.
