Abstract

Abstract: FCC slurry is of low value when it is used as fuel component and its high value application is of interest in recent years. The processes of high value utilizations of FCC slurry were reviewed. Especially,the industrialized processes of FCC blending with coke feed,blending with reduced crude to get more gas oil,blending with vacuum residue as feed of solvent deasphalting and distilling units to get asphaltenes were described. Meanwhile,the research results of processing of slurry with coal,solvent extraction of slurry to get aromatics rich fractions to produce chemical products and thermal cracking of slurry to get asphaltene upgrading component were described. The features of the processes were described also. For high value utilizations of slurry,blending process is reliable and easy to accomplish,but the value added is not obvious and the process is restricted by the existed unit of refinery and the volume of blending. The value increase of other processes is obvious,but additional units and investment are required. Therefore the processing of slurry by collection will be a valuable method in large scale utilization.

Key words: catalytic cracking, slurry, higher value application

摘要： 催化裂化油浆直接作为燃料油的调和组分出售,经济价值较低,近年来其高值化利用技术备受关注。本文介绍了催化裂化油浆高值化利用技术研究现状,重点介绍了已工业化应用的催化裂化油浆掺炼作为延迟焦化原料技术、掺炼入常渣减压装置提高蜡油收率技术、掺炼作为溶剂脱沥青原料技术、蒸馏分离出沥青组分调和生产道路沥青技术及其特点,同时介绍了催化裂化油浆与煤共炼提高附加值、利用溶剂分离出富芳组分生产化工产品、直接热裂化生产沥青改质组分技术研究结果及其特点。从目前油浆高值化利用途径来看,油浆掺炼工艺成熟,易于实现,但价值提升不显著,同时受到炼厂现有生产装置及掺炼数量的限制,其他利用途径高值化效果显著,但需要新增设备投资,因而催化油浆的集中加工处理将是具有规模效应的有效利用途径。
