日本石油公司开发的用于高苛刻度流化催化裂化工艺(HS-FCC)的催化剂,目前将实现工业化应用。该催化剂是Y型沸石含量最大化的催化剂,以限制二级氢转移反应,避免生成烷烃,同时也改善了反应效果。另外,通过在专有催化剂内添加ZSM-5沸石,可使丙烯产量增加4倍。近年来,丙烯的巨大需求迫使炼油厂朝着不断提高丙烯收率的方向努力。日本石油公司于2003—2005年在 Catalysts developed by Nippon Oil for HS-FCC are currently being commercialized. The catalyst is a Y-type zeolite to maximize the catalyst to limit the secondary hydrogen transfer reaction to avoid the formation of alkanes, but also improve the reaction effect. In addition, propylene production can be increased by a factor of four by adding ZSM-5 zeolite in a proprietary catalyst. In recent years, the huge demand for propylene has forced refineries to work toward increasing propylene yields. Nippon Oil Company in 2003-2005 at
