| 简介 |
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. |
