加氢裂化催化剂级配工艺研究

Research on grading process of hydrocracking catalysts

介绍了抚顺石油化工研究院(FRIPP)开发的加氢裂化催化剂级配技术。通过不同类型加氢裂化催化剂(C/A-B)级配实验后发现,与单一类型催化剂相比,采用级配装填工艺可以在提供优质、清洁油品的同时,降低装置冷氢用量,生产芳潜较高的重石脑油、高烟点喷气燃料、低凝柴油及BMCI值较低的加氢裂化尾油等,满足炼厂不同时期对石化原料和燃料油的需求。此外,该技术相对提高了反应器出口温度,提高了后续换热器的热源温度,为炼厂节能降耗提供新的途径。

This paper introduced hydrocracking catalysts grading technology developed by Fushun Research Institute of Petroleum and Petrochemicals （FRIPP） .Test results of hydrocrac-king catalysts grading （C/A-B） showed that using grading loading technology could not only pro-vide qualified clean fuel ,but also reduce the cooled hydrogen consumption of refinery ,and it could produce heavy naphtha with high aromatic potential ,jet fuel with high smoking point , diesel with low solidifying point and hydrocracking residue with low BMCI value ,which could meet demands of petrochemical feedstock and fuel for refinery at different stages .Moreover ,this technology could relatively raise the outlet temperature of hydrocracker along with increase of heat source temperature of heat-exchanger .
