Study on preparation of fuel oil from waste cooking oil and process of catalytic reforming

摘要

Fuel oil was prepared from waste cooking oil by catalytic cracking and catalytic reforming processes. The preparation of reforming catalyst and the process of catalytic reforming have been investigated. The conditions of the preparation of reforming catalyst were as follow: ZSM-5/H38 zeolite was using as the catalytic carrier, calcination temperature was 550°C and lanthanum oxide content was 6%. Reforming catalyst was used to catalyze the catalytic reforming reaction at 360°C. The results showed that the alkene in fuel oil decreased with the light components increased, the total yield of fuel oil was 84.41%. The proportion of gasoline, diesel oil, heavy oil, non-condensable gas and residue in the product were 9.76%, 69.84%, 4.81%, 11.74% and 3.85%, respectively.
