Abstract: To reduce diesel yield and increase the yield of heavy naphtha as reforming feedstock, unconverted diesel oil as raw material of ethylene cracking unit, PetroChina Petrochemical Research Institute has developed diesel oil hydrocracking catalyst(PHU-211) for high yield chemical material production, and its first industrial application was carried out in 1.2 Mt/a diesel hydrogenation cracking unit of Fushun petrochemical company. By the diesel oil hydrocracking catalyst(PHU-211), heavy naphtha with aromatic potential of more than 46% and the yield of 30%~38% has been produced, and it is high-quality reforming feedstock, its BMCI value is less than 7; The diesel with the yield of 25%~ 30% has also been produced, and it is better raw material for ethylene cracking unit; The yield of chemical raw materials can reach 70%, so the efficient conversion of catalytic diesel and coking diesel has been realized.
Key words: Chemical raw material; Hydrocracking; Catalyst; First industrial application
1 概述
近年来,我国油品市场呈现出柴油消费量降低、柴汽比不断下降的趋势,另一方面,炼油厂内部还存在重整装置原料不足、重石脑油短缺的问题,解决上述问题的较好方法是采用柴油加氢裂化技术,依托现有的柴油加氢精制、加氢改质装置进行改造,并更换性能优异的柴油加氢裂化催化剂来降低柴汽比、实现炼化一体化高度融合发展[1-5]。
针对降低柴油产量,增产重石脑油作重整原料、未转化柴油作乙烯裂解原料的市场需求,中国石油石油化工研究院开发了多产化工原料的柴油加氢裂化催化剂(PHU-211),并在抚顺石化公司120万t·a-1柴油加氢裂化装置进行了首次工业应用,本文介绍了催化剂应用的相关情况。
抚顺石化公司120万t·a-1柴油加氢裂化装置,主要对重油催化柴油、焦化柴油的混合油进行加氢裂化,多产重石脑油,其具有较高的芳烃潜含量,可作为优质的重整原料,生产的柴油作为国VI柴油调和组分。……
