In order to reduce the rapeseed oil cracking fuel acid value,increase the stability of the fuel performance,the 1- (4-sulfonic acid) butyl-pyridinium hydrosulfate was applied in cracking fuel esterification reaction.The influence of the dosage of catalyst,reaction time and reaction temperature on the acid value was examined,and under the optimization condition the physical and chemical properties of fuel pyrolysis products was investigated. The results showed that,1-(4-sulfonic acid) butyl-pyridinium hydrosulfate in catalytic esterification reaction had the very high catalytic activity.The optimization of process conditions as follows:1.2%of catalyst,reaction temperature 75 ℃,reaction time 70 min. Under the optimization condition,the acid value reduced to less than 1.0 mgKOH/g.
