US Patent:

20120261310, Oct 18, 2012

Filed:

Oct 4, 2011

Appl. No.:

13/252836

Inventors:

George A. HADJIGEORGE - Sugar Land TX, US
Easwar Santhosh RANGANATHAN - Houston TX, US

Assignee:

SHELL OIL COMPANY - Houston TX

International Classification:

C10G 11/05

US Classification:

20812001

Abstract:

A catalytic cracking process that processes a Fischer-Tropsch derived waxy feedstock and which is operated in a heat balanced mode without the use of additional heat sources or heavy feedstock. Heat is provided by the coke yielded from cracking of the Fischer-Tropsch derived waxy feedstock. A combination of the use of a high rare earth oxide large pore zeolite cracking catalyst with the operation of the riser reactor under suitable cracking conditions provide a spent cracking catalyst having a coke content sufficient to provide for the heat balance in the operation of the catalytic cracking system.

International Classification:

C10G 69/04

US Classification:

208 61

Abstract:

A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a non-acidic metal-containing catalyst at a temperature of 375 C. to 500 C. to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal at a temperature of 260 C.-425 C. to produce a second hydrocarbon-containing product. The second hydrocarbon-containing product is separated into fractions, one of the fractions being a heavy hydrocarbon fraction comprised of hydrocarbons having a boiling point of at least 343 C. The heavy hydrocarbon fraction is then contacted with a fluidizable cracking catalyst at a temperature of at least 500 C.

International Classification:

C10G 1/06

US Classification:

44307

Abstract:

A process for converting a solid biomass material, comprising contacting the solid biomass material and a hydrocarbon co-feed with a catalytic cracking catalyst at a temperature of more than 400 C. in a riser reactor to produce one or more cracked products, wherein the solid biomass material is introduced to the riser reactor at a location downstream of the location where the hydrocarbon co-feed is introduced to the riser reactor.

International Classification:

C07C 27/06
C10G 57/00

US Classification:

518702, 208 67

Abstract:

A process for the preparation of alkylate and middle distillate, the process comprising: (a) catalytically cracking a first hydrocarbon feedstock by contacting the feedstock with a cracking catalyst comprising a shape-selective additive at a temperature in the range of from 450 to 650 C. within a riser or downcomer reaction zone to yield a first cracked product comprising middle distillate and a spent cracking catalyst; (b) regenerating the spent cracking catalyst to yield a regenerated cracking catalyst; (c) contacting, within a second reaction zone, at least part of the regenerated cracking catalyst obtained in step (b) with a second hydrocarbon feedstock at a temperature in the range of from 500 to 800 C. to yield a second cracked product and a used regenerated catalyst, the second feedstock comprising at least 70 wt % C hydrocarbons obtained in a Fischer-Tropsch hydrocarbon synthesis process; (d) using the used regenerated catalyst as at least part of the cracking catalyst in step (a); and (e) alkylating at least a portion of the second cracked product in an alkylation unit to obtain alkylate.
