Abstract
Disclosed herein is a catalyst component suitable for petroleum refining applications (e.g., fluid catalytic cracking and hydrocracking) that includes a MSB zeolite structure (e.g., MCM-68) and a non-zeolitic matrix. The first component may be combined with additional components into a catalyst composition. Also disclosed herein are methods of preparing the catalyst component and/or catalyst compositions as well as method of using the catalyst component and/or catalyst composition.
Claims17
A process for fluidized catalytic cracking (FCC) of a hydrocarbon feedstock, the process comprising:
- contacting, under FCC process conditions, a feedstock comprising at least petroleum crude oil fractions with a first catalyst component comprising a phosphorus stabilized MCM-68 zeolite and a first non-zeolitic matrix, to produce products comprising at least gasoline and olefinic gases.
A catalyst component comprising microspheres including:
- phosphorus stabilized MCM-68 zeolite having from about 0.5 wt % to about 10 wt % phosphorus, based on total weight of the phosphorus stabilized MCM-68 zeolite in the catalyst component;
- and
- a non-zeolitic matrix comprising one or more of clay, spinel, mullite, kaolin, metakaolin, halloysite, kaolinite, dickite, nacrite, anauxite, silica-thoria, silica-beryllia, and silica-alumina-thoria;
- wherein the phosphorus stabilized MCM-68 zeolite is present in the catalyst component from about 1 wt % to about 90 wt %.
A catalyst composition comprising:
- first catalyst component microspheres comprising a phosphorus stabilized MCM-68 zeolite having from about 0.5 wt % to about 10 wt % phosphorus, based on total weight of the phosphorus stabilized MCM-68 zeolite in the first catalyst component, and a first non-zeolitic matrix;
- and
- second catalyst component microspheres comprising a second zeolite having a pore size greater than 7 angstroms, and a second non-zeolitic matrix;
- where the first catalyst component microspheres are present in the catalyst composition in an amount ranging from about 1 wt. % to about 25 wt. %, based on the total weight of the catalyst composition.
