Patent number: 4873214Abstract: A process for the catalytic production of hydrogen, from a wide variety of low heating value fuel gases containing carbon monoxide, comprises circulating a carbonaceous material between two reactors--a carbon deposition reactor and a steaming reactor. In the carbon deposition reactor, carbon monoxide is removed from a fuel gas and is deposited on the carbonaceous material as an active carbon. In the steaming reactor, the reactive carbon reacts with steam to give hydrogen and carbon dioxide. The carbonaceous material contains a metal component comprising from about 75% to about 95% cobalt, from about 5% to about 15% iron, and up to about 10% chromium, and is effective in suppressing the production of methane in the steaming reactor.Type: GrantFiled: June 30, 1987Date of Patent: October 10, 1989Assignee: TRW Inc.Inventor: Elias P.

Patent number: 4519894Abstract: A carbon-containing solid (such as oil shale or tar sand) is treated with air in a six-stage vertical shaft to make producer gas, oil and a pure carbon as products. The top and bottom stages of the vertical shaft are fed to pre-heat incoming solid and to scavenge sensible heat from the processed solid. One stage is a direct retort and makes a gas stream which is a mixture of producer gas and oil. Another stage is a gas producer which converts fixed carbon on the solid to carbon monoxide by reaction with air and carbon dioxide. A fifth stage preheats incoming air. The sixth stage cools and purifies hot carbon monoxide-rich producer gas.The oil and producer gas products are made by direct retorting of the solid with air followed by a separation step. The pure carbon product is made by separating pure carbon monoxide from the carbon monoxide-rich producer gas followed by reacting the carbon monoxide to carbon dioxide and the pure carbon product.Type: GrantFiled: August 17, 1984Date of Patent: May 28, 1985Inventor: David G.
