Abstract
Disclosed herein is a fluid catalyst cracking (FCC) catalyst composition that includes a first component and a second component. The first component includes zeolite Y and a first matrix that includes a metal passivating constituent. The second component includes beta zeolite and a second matrix. Also disclosed herein are methods of preparing the FCC catalyst composition and method of using the FCC catalyst composition.
Claims21
A fluid catalytic cracking (FCC) catalyst composition comprising:
- a first component comprising Y zeolite and a first matrix, the first matrix comprising clay, rare-earth-doped alumina, silica-alumina, silica-doped alumina, χ-alumina, δ-alumina, θ-alumina, κ-alumina, boehmite, spinel, mullite, or a combination of any two or more thereof,
- wherein the first matrix further comprises a metal passivating constituent comprising a transitional alumina, the first component comprising 1 wt % to 80 wt % of the transitional alumina based on total weight of the first component;
- and
- a second component comprising beta zeolite and oxidized phosphorus and a second matrix comprising non-zeolitic material;
- wherein a weight ratio of the first component to the second component in the FCC catalyst composition ranges from 1.5:1 to about 20:1.
