Abstract:

A process for producing polypropylene from olefins selectively produced from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0. 7 nanometers at reaction conditions which include temperatures from about 500Â C. to 650Â C. and a hydrocarbon partial pressure from about 10 to 40 psia. The catalyst may be pre-coked with a carbonaceous feed. Alternatively, the carbonaceous feed used to coke the catalyst may be co-fed with the naphtha feed.

US Classification:

502 60, 502 63, 502 64, 502 68, 502 79

Abstract:

This invention relates to a mesoporous catalytic cracking catalyst, a process for the production of such catalysts, and a process utilizing such catalysts in cracking operations. The mesoporous fluidized catalytic cracking catalyst is selective for minimizing the production of coke and light gas. The catalyst comprises an amorphous, porous matrix having pores ranging in diameter from about 1 Å to about 10 Å and ranging in diameter from about 40 Å to about 500 Å, but substantially free of pores ranging in diameter from about 10 Å to about 40 Å.

International Classification:

C10G 11/05

US Classification:

20812001

Abstract:

This invention relates to a FCC process using a mesoporous catalytic cracking catalyst. The mesoporous fluidized catalytic cracking catalyst is selective for minimizing the production of coke and light gas. The catalyst comprises at least one amorphous, porous matrix, each matrix having pores ranging in diameter from about 1 Å to about 10 Å and pores ranging in diameter from about 40 Å to about 500 Å, wherein in the pore range from 50 Å to 250 Å, there is a single maximum in differential pore volume distribution over the 50 Å to 250 Å range.

International Classification:

B01J 35/02

US Classification:

502 60

Abstract:

Catalysts for experimentation are produced having a controlled matrix pore structure. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50 C. to 200 C. for a period of time of about 0. 1 to 1. 0 hour. The dried catalyst particles can be removed from the substrate by several techniques, including scraping, burning, and deforming the substrate material. The resulting catalytic particles can be produced in an amount of about ca. 3 g to 300 g from slurries with volumes between 5 cc to 500 cc, which are suitable for small scale FCC reactors and for high throughput experimentation.

International Classification:

C10G 11/02

US Classification:

20812001

Abstract:

This invention relates to the composition, method of making and use of a fluidized catalytic cracking (“FCC”) catalyst that is comprised of a new Y zeolite which exhibits an exceptionally low small mesoporous peak around the 40 Å (angstrom) range as determined by nitrogen adsorption measurements. FCC catalysts made from this new zeolite exhibit improved rates of heavy oil cracking heavy oil bottoms conversions and gasoline conversions. The fluidized catalytic cracking catalysts herein are particularly useful in fluidized catalytic cracking (“FCC”) processes for conversion of heavy hydrocarbon feedstocks such as gas oils and vacuum tower bottoms.
