摘要
通过添加一种水热稳定性高、大分子裂化能力强、焦炭选择性好、成本低、易于工业化的无序介孔硅铝材料(JSA),开发出一种新型的催化裂化催化剂CRM-200,并在青岛安邦炼化重油催化裂化装置上进行工业应用。结果表明,CRM-200催化剂具有优异的裂化活性,液体收率增加1.86百分点,油浆及焦炭产率分别降低0.92和1.59百分点,产品分布更加优化,产品性质得到改善;装置的处理能力明显提高,回炼量增加,掺渣率由69.92%提高到83.34%,操作条件更加优化,催化剂单耗大幅降低近1kg/t。
A new FCC catalyst CRM-200 was prepared with a kind of disordered mesoporous silicaalumina material（JSA）and was used on a RFCC unit of Qingdao Anbang Company.The material JSA with low cost and easy to be industrialized possesses high hydrothermal stabilities and cracking activities of heavy oil as well as excellent selectivity of coke.The industrial application results reveal that CRM-200 shows much higher cracking activity,the total liquid yield increases about 1.86 percentage points,the yield of slurry and coke decreases 0.92 percentage point and 1.59 percentage points,respectively.The distribution and properties of cracking products are improved.The processing capacity and recycle oil increases.The resid-ratio increases from 69.92%to 83.34%.The operation condition is optimized,at the same time the catalyst consumption reduces about 1kg/t.
