RMMC-1(恒源)催化剂在300kt/a催化裂化装置的工业应用

介绍了RMMC-1(恒源)催化剂在山东恒源石油化工集团有限公司300kt/a催化裂化装置的工业应用情况。针对原料油的特点,RMMC-1(恒源)催化剂的设计强调抑制原料油初次反应中的芳构化和异构化反应,一方面保证长的直链烃全程参与裂解反应,另一方面尽量增加环烷烃的开环几率,降低脱氢缩合比例。催化剂基质具有大比表面积,能有效应对碱氮等污染物的影响、提高重质油的裂化能力,同时实现多产丙烯的目的。工业运行结果表明,与空白标定相比,总液体收率及轻油收率变化不大,液化气和丙烯收率略有增加,汽油收率上升3.4百分点,柴油收率下降4.4百分点,原料的转化率上升4.1百分点,干气收率下降0.4百分点,焦炭选择性明显优化。

APPLICATION OF RMMC-1(HENGYUAN) IN 300 kt/a FCCU

The commercial application of RMMC-1 (Hengyuan) in Shandong Hengyuan Petrochemical Company was introduced. Ltd. Considering the inferior feedstock such as CGO, the emphasis in design of RMMC-1 (Hengyuan) catalyst was put on the inhibition of aromatization and isomerization reactions as much as possible during the initial oil-catalyst contact to ensure long straight-chain hydrocarbon involved in cracking reaction and to increase the ring opening probability of naphthene and reduce the proportion of dehydrocyclization and condensation. The matrix of RMMC-1(Hengyuan) catalyst is characterized by large surface areas, which can effectively deal with the influence of basic nitrogen and other pollutants on the catalyst performance and improve the ability of heavy oil cracking and the yield of propylene. The running results show that the yield of total liquid and of light oil changes little, LPG and propylene yields increase. The conversion rate of feedstock and the gasoline yield increases 4.1 percentage points and 3.4 percentage points, respectively. While the yield of dry gas and diesel reduces 0.4 percentage point and 4.4 percentage points，respectively. The coke selectivity is significantly improved.
