TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In process (P1), the stream comprises a predominant amount of methane. A char is formed in step (b), and the char is removed from the gasifying reactor and sent to a catalyst recovery and recycle process. The gasification catalyst comprises gasification catalyst recycled from the catalyst recovery and recycle process. In process (P2), (F1) and (F2) are contacted with an aqueous solution comprising the gasification catalyst to form a slurry; the slurry is dewatered to form a catalyst-loaded wet cake in the form of a mixture, which is thermally treated to form the particulate composition (preferably F1 and F2 are contacted separately with an aqueous solution comprising the gasification catalyst to form a first and a second slurry, the first and second slurries are dewatered separately to form a first and a second catalyst-loaded wet cake, which are combined to form the mixture which is then thermally treated to form the particulate composition or the first and second catalyst-loaded wet cakes are thermally treated to form first and second dry particulates; and the first and second dry particulates are combined to form the mixture which is the particulate composition) or F1/F2 is contacted with an aqueous solution comprising the gasification catalyst to form a slurry; the slurry is dewatered to form a catalyst-loaded wet cake; and the catalyst-loaded wet cake is mixed with the F2/F1 carbonaceous feedstock respectively to form the mixture. Preferred Components: The alkali metal comprises potassium and/or sodium (preferably potassium). The particulate composition (C1) has a particle size of 25 to 2500 microns. The non-biomass comprises the gasification catalyst. EXAMPLE - Coal was stage-crushed to maximize the amount of material having particle sizes ranging from 0.85 to 1.4 mm. Fines (less than 0.85 mm) were separated from the crushed materials by vibratory screening and directed to the steam generating combustion reactor. The crushed coal was slurried with an aqueous solution of potassium carbonate, dewatered, and dried via a fluid bed slurry drier to yield a catalyzed feedstock typically containing coal (185 lb, 88 wt.%); catalyst (14.9 lb, 7 wt.%) and moisture (10.5 lb, 5 wt.%). The coal fines separated at the crushing stage were subsequently used as the feedstock for combustion reactor for the preparation of steam. Switchgrass was dried and crushed to produce a particulate having an average size of about 250 microns was blended with the coal fines in a twin screw mixer to produce a biomass feedstock having a 9:1 wt./wt. ratio of the switchgrass to coal fines. The biomass feedstock was provided to a combustion reactor fed by an enriched oxygen source. The resulting exhaust gas from the combustion reactor contained hot CO2. The exhaust gas was passed through a heat exchanger in contact with a water source to produce steam. The generated steam and the exhaust gas from the combustion reactor were superheated and then introduced to a fluidized bed gasification reactor (catalytic gasifier) supplied with the catalyzed feedstock introduced under a positive pressure of nitrogen (i.e. total pressure, 500 psi and temperature, 1200 degrees F). The effluent of the catalytic gasifier contained methane, hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide (H2S), ammonia, water, and nitrogen, which was passed to a scrubber to remove ammonia, and an acid gas removal unit to remove H2S and CO2 and cover CO2.
