| 简介 |
本发明阐述流体催化裂解(FCC)组合物、制造及使用方法。FCC触媒组合物含有包含沸石、非沸石组份及稀土组份之催化微球。该等微球经磷改质。该FCC触媒组合物可用於裂解烃进料，尤指包含高V及Ni之残油进料，从而降低氢及焦炭产率。 Described are fluid catalytic cracking (FCC) compositions, methods of manufacture and use. FCC catalyst compositions comprise catalytic microspheres containing a zeolite, a non-zeolitie component, and a rare earth component. The microspheres are modified with phosphorus. The FCC catalyst composition can be used to crack hydrocarbon feeds, particularly resid feeds containing high V and Ni, resulting in lower hydrogen and coke yields. |
