NOVELTY - Particulate composition having a particle distribution size suitable for gasification in a fluidized bed zone comprises an intimate mixture of a biomass char leachate comprising one or more soluble alkali metal compounds, and a carbonaceous feedstock, where: the biomass char leachate comprises an aqueous extract of a biomass char and gasification catalyst comprising the soluble alkali metal compounds from the biomass char leachate; and the gasification catalyst exhibits gasification activity in the presence of steam and under suitable temperature and pressure.    USE - The particulate composition is useful to form gaseous products, preferably methane (claimed).    ADVANTAGE - The particulate composition increases the overall utilization and conversion of the feedstocks, hence the gasification process is inexpensive.    DETAILED DESCRIPTION - Particulate composition having a particle distribution size suitable for gasification in a fluidized bed zone, comprises an intimate mixture of a biomass char leachate comprising one or more soluble alkali metal compounds, and a carbonaceous feedstock, where: the biomass char leachate comprises an aqueous extract of a biomass char and gasification catalyst comprising the soluble alkali metal compounds from the biomass char leachate; the gasification catalyst exhibits gasification activity in the presence of steam and under suitable temperature and pressure and where many gases comprising methane and one or more of hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia or other higher hydrocarbons are formed; and the gasification catalyst comprises a source of alkali metal and is present in an amount sufficient to provide a ratio of alkali metal atoms to carbon atoms of 0.01-0.10, in the particulate composition. INDEPENDENT CLAIMS are included for:    (1) a process for preparing the particulate composition comprising (a) providing particulates of the biomass char and a particulate carbonaceous feedstock other than the biomass char, (b) contacting the biomass char with water under suitable temperature and pressure to substantially extract the alkali metal compounds from the biomass char and form a leachate comprising soluble alkali metal compounds, (c) contacting the carbonaceous feedstock with the leachate to form a slurry, (d) dewatering the slurry to form a wet cake, and (e) thermally treating the wet cake with an inert dry gas to provide particulate composition; and    (2) a process for converting the particulate composition into a many gaseous products, comprising supplying the particulate composition to a gasifying reactor, reacting the particulate composition 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 monoxide, carbon dioxide, hydrogen sulfide, ammonia or other higher hydrocarbons, and at least partially separating many gaseous products to produce a stream comprising a predominant amount of one of the gaseous products.
