LTAG工艺专用催化剂SLG-1的研发与应用

针对加氢催化裂化轻循环油（LCO）的性质特点，开发了具有丰富中孔结构和强B酸活性的高可接近性Y型分子筛，具有更高的开环裂化反应能力。在此基础上，匹配重油预裂化能力和容炭能力强的基质，开发了加氢LCO回炼专用催化裂化催化剂SLG-1。工业应用结果表明：液化气收率降低了1.58百分点，汽油收率增加了4.00百分点，总液体收率增加2.17百分点。

DEVELOPMENT AND APPLICATION OF SLG-1 CATALYST FOR LTAG TECHNOLOGY

The high accessibility Y zeolite with an abundant mesoporous structure and strong B acid activity were designed according to the reaction features of hydrotreated light circulating oil (LCO). The resulting Y zeolite has an improved ring-opening ability. Combined with the matrix with heavy oil pre cracking capacity and strong carbon tolerance, a special catalytic cracking catalyst SLG-1 for processing hydrotreated LCO was developed. The industrial application results showed that the yield of LPG is reduced by 1.58 percentage points, the gasoline yield increases by 4 percentage points, and the total liquid yield improves by 2.17 percentage points.
