摘要: 开发了一种石脑油加氢精制催化剂LY-2010,以中国石油兰州石化公司直馏石脑油为原料,在360 mL绝热评价装置上对LY-2010与国内参比剂进行了对比评价,结果表明LY-2010催化剂在重整预加氢反应器入口温度较使用参比剂时低10 ℃的条件下,加氢性能依然略优于参比剂。LY-2010催化剂在中国石油辽阳石化公司1.4 Mt/a连续重整装置首次工业应用,一次开车成功,在入口温度274 ℃、反应压力2.2 MPa、体积空速5.0 h-1的条件下,加氢石脑油产品硫、氮质量分数均小于0.5 μg/g,完全满足重整装置进料指标的要求。

Abstract: A pre-hydrofining catalyst LY-2010 for catalytic reforming feed was developed by Petrochemical Research Institute of CNPC and evaluated using SR naphtha from Lanzhou Petrochemical Company in a 360ml hydrogenation reactor. The results were compared with that of a domestic reference catalyst. The results showed that the hydrogenation performance of LY-2010 is better than that of the reference catalyst though the inlet temperature of LY-2010 is 10℃lower. The catalyst was successfully applied in the 1.4 Mt/a CCR unit of Liaoyang Petrochemical Company. Both sulfur and nitrogen content of the hydrofined product are less than 0.5 μg/g under reaction conditions of 274 ℃, 2.2 MPa and LHSV of 5.0 h-1,in compliance with the demand of reformer feed.
