EFFECT OF ZEOLITE CONTENT ON THE PERFORMANCE OF DIESEL HYDRO-UPGRADING CATALYST FOR MAXIMUM INCREASING ETHYLENE FEEDSTOCK
In order to reduce oil and increase chemical,decrease the diesel/gasoline ratio,broaden the source of ethylene feedstock,and improve the economic benefit of refining and chemical enterprises,the straight-run diesel can be used as ethylene feedstock after hydro-upgrading.The effects of zeolite content in the catalyst on the yield and properties of modified diesel at different reaction temperature were investigated.The results showed that the total acid content and weak acid ratio of the catalyst increased with the increase of zeolite content.The aromatics index(BMCI)of modified diesel decreased with the increase of zeolite content and reaction temperature,but the yield decreased.At the yield of 50％,the BMCI of modified diesel could be reduced to 8.6 which was 25.7 less than that of the raw diesel,making it a high-quality ethylene feedstock.
