Richard A. Flinn - Pittsburgh PA, US

International Classification:

E21B 43/24

US Classification:

166369, 166302

Abstract:

A method for producing synthesis gas from underground hydrocarbon deposits is described. Oxygen and water are reacted with the hydrocarbon deposit under conditions conducive to the production of carbon monoxide and hydrogen. The method is applicable to oil reservoirs from which conventional production means are unable to recover additional oil practically, to viscous oil deposits from which production is limited, and to shale oil deposits.

International Classification:

C10G 9/00

US Classification:

208106

Abstract:

The present invention relates to a method of forming a paraffinic product that involves providing a paraffinic feed having an initial average carbon chain length of greater than 20. The paraffinic feed is a product of a gas-to-liquids process, such as a Fischer-Tropsch process. The paraffinic feed is subjected to thermal cracking at elevated temperature and elevated pressure, which results in the formation of a paraffinic product. The paraffinic product has a final average carbon chain length of less than or equal to 20. The paraffinic product is typically liquid at ambient temperature, such as at 25 C.

Abstract:

A catalytic amount of ammonia or ammonium compounds are utilized to prevent deterioration of alkanolamines employed in gas sweetening processes. The ammonia is added either to the sour gas or the absorbing solution and acts to suppress thiocyanate. [. formation. ]. . Iadd. accumulation. Iaddend. during absorption. BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to gas purification and more particularly to gas purification by the removal of acid gases from industrial gas in an absorption/desorption process. 2. Prior Art The term "gas sweetening" pertains to gas purification processes in which acid gases, particularly sulfurous gases are removed from industrial gases. Gas sweetening processes commonly utilize aqueous absorbing solutions into which the acid gases are scrubbed (absorbed) to be later stripped (desorbed) for possible further treatment. Desorbing is accomplished by heating the spent solution to expel the acid gases.

Abstract:

A method for reducing catalyst attrition losses in hydrocarbon synthesis processes conducted in high agitation reaction systems; a method of producing an attrition-resistant catalyst; a catalyst produced by such method; a method of producing an attrition-resistant catalyst support; and a catalyst support produced by such method. The inventive method of reducing catalyst attrition losses comprises the step of reacting a synthesis gas in a high agitation reaction system in the presence of a catalyst. In one aspect, the catalyst preferably comprises a. gamma. -alumina support including an amount of titanium effective for increasing the attrition resistance of the catalyst. In another aspect, the catalyst preferably comprises a. gamma. -alumina support which has been treated, after calcination, with an acidic, aqueous solution. The acidic aqueous solution preferably has a pH of not more than about 5.
