A zone of increased heat and enhanced fluid mobility is established between an injection well and a production well vertically traversing a heavy oil (bitumen, tar) reservoir by (a) first horizontally hydraulically fracturing between the wells, and (b) then injecting hot water and/or steam into the injection well at a very high rate, at a sufficient pressure, and for a sufficient time (holding sufficient back pressure on the production well if needed) to float the formation along the fracture system between the wells, to effect channel flow of fluids through the floated fracture system (with production from the production well), and to effect effective and uniform heating of substantial reservoir volume perpendicular to the channel flow. Thereupon, other thermal methods such as matrix flow steam flooding can be employed to recover additional oil.

Fracture preheat oil recovery process

A method is provided wherein nickel molybdenum and cobalt molybdenum catalysts can be used in large scale sulfur hydrogenation reactors without runaway methanation and resulting exotherms while converting organic sulfur compounds to hydrogen sulfide in gas streams which contain significant quantities of carbon monoxide, carbon dioxide, and hydrogen.

Hydrodesulfurization purification process for coal gasification

A method for activating a hydrodesulfurization catalyst by passing a gaseous stream comprising carbon oxides, hydrogen, and sulfur-containing compounds into contact with the catalyst at a temperature from about 400.degree. to about 700.degree. F. until the outlet gaseous stream from the catalyst has a sulfur content substantially equal to the sulfur content of the inlet gaseous stream and thereafter increasing the temperature incrementally and continuing to contact the catalyst with the inlet gas stream until the sulfur content in the outlet gaseous stream is substantially equal to the sulfur content of the inlet gaseous stream after each incremental temperature increase.
