NOVELTY - Particulate composition (I) having a particle distribution size suitable for gasification in a fluidized bed zone, comprises an intimate mixture of a petroleum coke, coal and gasification catalyst, in which, in the presence of steam and under suitable temperature and pressure, (I) exhibits gasification activity thus many gases comprising methane and one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other higher hydrocarbons are formed.    USE - (I) is useful for gasification in a fluidized bed zone for forming many gases comprising methane and one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other higher hydrocarbons.    ADVANTAGE - (I) can provide an economical and commercial catalytic gasification of coals, such as lignites or sub-bituminous coal, with high ash and moisture contents to yield methane and other value-added gases as a product. (I) reduces or eliminates some technical challenges associated with the catalytic gasification of petroleum coke.    DETAILED DESCRIPTION - Particulate composition (I) having a particle distribution size suitable for gasification in a fluidized bed zone, comprises an intimate mixture of a petroleum coke, coal and gasification catalyst, in which, in the presence of steam and under suitable temperature and pressure, (I) exhibits gasification activity, thus many gases comprising methane and one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other higher hydrocarbons are formed, where: the petroleum coke and the coal are present at a weight ratio of 5:95-95:5; the gasification catalyst is loaded onto at least the coal; the gasification catalyst comprises a source of at least one alkali metal and a ratio of alkali metal atoms to carbon atoms is 0.01-0.08; and (I) comprises a total ash content of less than 20 wt.%. INDEPENDENT CLAIMS are included for:    (1) a process for converting (I) into many gaseous products, comprising (a) supplying (I) to a gasifying reactor, (b) reacting (I) in the gasifying reactor in the presence of steam and under suitable temperature and pressure to form many gaseous including methane and one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and other higher hydrocarbons and (c) at least partially separating the gaseous products to produce a stream comprising a predominant amount of one of the gaseous products; and    (2) a process for preparing (I), comprising providing petroleum coke particulates, coal particulates and gasification catalyst, contacting the coal particulates with an aqueous solution comprising gasification catalyst to form a slurry, dewatering the slurry to form a catalyst-loaded wet coal cake, and kneading the wet coal cake and the petroleum coke particulates to form (I).
