A Combination Process for Improved Hydrotreating and Catalytic Cracking of Hydrocarbon oils

摘要

Abstract: the present invention relates to an improved joint treatment with hydrogen and catalytic cracking of hydrocarbon oils, which comprises: contact with oil, residual oil, smashing recycling Catalytic distillation, an oil output to tPA treatment of hydrogen under the conditions of treatment of hydrogen in the presence of hydrogen interaction in turn separate products for the gas, naphtha and pain Hydrogenated diesel oil hydrogenation, and caudal hydrogenated oil; oil in contact with the hydrogenated tail oil are xOptional TPA or plain feed catalytic cracking cracking under conditions of catalytic cracking reaction products in turn separated to obtain hydrogenated Nftha dry gas, liquefied petroleum gas, a broken gas catalysis. Hey, crushed catalytic diesel oil, recycling oil catalytic smashing; where the hydrogenated tail oil are separated and / or normal feedstock oil catalytic cracking at least two parts, the parts are hidden. Selection and heavy or regular heavy feedstock oil catalytic cracking crude oil effective organisational culturalThe average light Dhyt catalytic cracking, prior to contact with the hydrogenated tail oil are and / or normal feedstock oil catalytic cracking cracking TPA. The process according to the present invention is specially suitable for conversion of hydrocarbon oils to produce more products, gasoline and diesel oil. Form (1).
