Horizontal Fluid Bed Retorting Process
US Patent:
4464247, Aug 7, 1984
Filed:
Oct 13, 1983
Appl. No.:
6/541525
Inventors:
Milton B. Thacker - Salt Lake City UT
Assignee:
Standard Oil Company (Indiana) - Chicago IL
International Classification:
C10G 102, C10B 5306
US Classification:
208 11R
Abstract:
A horizontal fluid bed retorting process is provided for preheating, retorting, combusting, and recovering heat from oil shale and other solid hydrocarbon-containing material. In the process, the combustor and heat recovery chambers share a common heat-conductive metal wall with and are positioned in side-by-side relationship to the cellular preheating and retorting chambers. The heat of combustion in the combustor and the heat recovered from the combusted shale or other material in the heat recovery chamber are transferred by conduction into the retorting and preheating chambers, respectively, to provide the process heat requirements for preheating and retorting the oil shale or other feed. The oil shale or other feed is fluidly moved in a generally horizontal S-shaped flow pattern through the preheating and retorting chambers in countercurrent flow to the combusted material in the combustor and heat recovery chambers.
Low Profile Fluid Catalytic Cracking Apparatus
US Patent:
4925632, May 15, 1990
Filed:
Aug 25, 1989
Appl. No.:
7/399433
Inventors:
Milton B. Thacker - Salt Lake City UT
John M. Limburg - Murray UT
Vincent J. Memmott - Centerville UT
John M. Limburg - Murray UT
Vincent J. Memmott - Centerville UT
International Classification:
B01J 818, B01J 826, F27B 1500
US Classification:
422142
Abstract:
A succession of low profile catalyst chambers each housing a reservoir of catalyst are alternately connected in sequence by openings below the levels of the catalyst reservoirs and openings thereabove. The catalyst in all reservoirs is fluidized by a gas moving upwardly therethrough. Separate portions of the sequence of chambers are operated as reactor and regenerator sections according to the gas used to fluidize the catalyst in those sections. Other portions of the sequence of chambers are used to create inert atmospheric seals between the reactor and regenerator sections. The entire apparatus is configured as a low-profile catalytic cracker wherein the fluidized flow of the catalyst moves throughout the apparatus in an alternating lifting and dropping sequence.
