Abstract:
Liquid hydrocarbons are converted to a methane rich gas stream by contact with a non-molten particulate alkali metal composition in a two-stage process wherein each stage is operated at pressures above 200 psig and temperatures above 1,000*F. Solid hydrocarbon material deposits on the particulate composition in the 1st stage and is converted to a gaseous product by reaction with steam in the 2nd stage.
Abstract:
Heavy mineral oils are upgraded by reaction with hydrogen in the presence of a catalyst comprising a solid carbon-containing material and an alkali metal component. The spent solids are reactivated in a catalytic gasification process.
Abstract:
Cesium salts derived from acids having an ionization constant below 1 X 10 3 and carried on a support having high-surface area are used to catalyze the reaction
Abstract:
A METHOD FOR REMOVING METALS AND SULFUR FROM PETROLEUM COKE BY PARTIAL GASSIFICATION OF THE COKE WITH STEAM AT ELEVATED PRESSURES AND TEMPERATURS. GASIFICATION OF LESS THAN APPROXIMATELY FIFTY PERCENT OF THE COKE WITH STEAM AT PRESSURES RANGING FROM ABOUT 100 TO 3,000 P.S.I.G. RESULTS IN SELECTIVE DISULFURIZATION OF THE UNCONVERTEDD COKE. TEMPERATURES RANGE FROM ABOUT 800 UP TO ABOUT 2500*F. THE EXTENT OF GASIFICATION RANGES FROM ABOUT 5 TO 50% OF THE COKE.
