摘要
采用碱土金属复合改性和固相稀土技术开发了低生焦活性缓释重油裂化催化剂M,在R石化公司重油催化裂化装置进行了工业应用。应用结果表明,在催化原料和操作工况大致相当的情况下,与空白标定相比,新催化剂M占系统藏量达到50%时,液收增加1.64个百分点,油浆收率和焦炭收率分别下降0.44和1.30个百分点,汽油收率增加0.62个百分点,柴油收率增加1.58个百分点,表明该催化剂重油转化能力强,生焦低。
The low-coke activity slow-release heavy oil cracking catalyst M was developed by alkaline earth metal composite modification and solid rare earth technology,and was used in the heavy oil catalytic cracking unit of R Petrochemical Company.The application results show that the catalyst has high conversion capacity of heavy oil and low coke production.Compared with blank calibration,when the new catalyst M accounted for 50%of the system reserve,the liquid yield increased by 1.64 percentage points,the oil slurry yield and coke yield decreased by 0.44 and 1.30 percentage points,the gasoline yield increased by 0.62 percentage points,and the diesel oil yield increased by 1.58 percentage points.
