为适应炼油厂重油催化加工的需要,该项成果开发成功了主要用于加工大庆类常压渣油或掺炼减压渣油的催化剂DOCR-1和Orbit系列渣油裂化催化剂.DOCR-1催化剂用骨架富硅Y型分子筛作为主要活性组元,以活性、稳定性优异的择型分子筛作为提高汽油辛烷值的活性组元,用REVSY或REHY作为辅助活性组 In order to meet the needs of heavy oil catalytic processing in refinery, this project succeeded in developing the DOCR-1 and Orbit series of residuum cracking catalysts which are mainly used for the processing of Daqing atmospheric residue or vacuum distillation residue. The silicon-rich Y zeolite was used as the main active component, the zeolite with excellent activity and stability as the active component to improve the octane number of gasoline, the REVSY or REHY as the auxiliary activity group
