| 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催化剂组合物含有包含非沸石组份及一或多种氧化硼组份之粒子。在实施例中，该FCC催化剂组合物包含沸石组份及视情况选用之稀土组份及过渡型氧化铝。FCC催化组合物可含有包含一或多种氧化硼组份及第一基质组份之第一粒子类型及与其混合之包含第二基质组份及沸石之第二粒子类型。该等FCC催化剂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 particles containing a non-zeolitic component and one or more boron oxide components. In embodiments, the FCC catalyst composition contains a zeolite component and optionally a rare earth component and a transition alumina. FCC catalytic compositions may comprise a first particle type containing one or more boron oxide components and a first matrix component mixed with a second particle type containing a second matrix component, and a zeolite. The FCC catalyst compositions can be used to crack hydrocarbon feeds, particularly resid feeds containing high V and Ni, resulting in lower hydrogen and coke yields. |
