TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: In the process, an exhaust produced from the partial combustion of the biomass feedstock is provided to the gasifier and the gas stream comprises carbon dioxide generated from the partial combustion of the biomass feedstock and the catalytic gasification of the carbonaceous feedstock. The steam is generated within the reactor. In the process, the heat energy is transferred to a heat exchanger in contact with a water source to produce the steam. The process further comprises: dividing the steam into at least a first steam stream and a second steam stream; introducing the first steam stream, a carbonaceous feedstock and an alkali metal gasification catalyst to a gasifier; introducing the second steam stream to a steam turbine to generate electricity; and reacting the carbonaceous feedstock in the gasifier in the presence of the first steam stream and the alkali metal gasification catalyst and under suitable temperature and pressure to form the gas stream. Preferred Components: The gas stream comprises carbon monoxide and hydrogen. The alkali metal gasification catalyst comprises a source of at least one alkali metal and is present in an amount sufficient to provide, in the carbonaceous feedstock, a ratio of alkali metal atoms to carbon atoms of 0.01-0.08. The biomass feedstock: is in a particulate form; and comprises aqueous slurry.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The reactor is a second gasifier or an oxygen combustor. EXAMPLE - Coal (Powder River basin) was stage-crushed to maximize the amount of material (particle sizes of 0.85-1.4 mm). The crushed coal was slurried with an aqueous solution of potassium carbonate, dewatered and dried via fluid bed slurry drier to yield a catalyzed feedstock. Switchgrass was dried and crushed to produce a particulate (particle sizes of 250 microns) to provide a biomass feedstock. The obtained switchgrass particulate was provided to a combustion reactor fed by an enriched oxygen source. The resulting exhaust gas from the combustion reactor contained hot carbon dioxide. The exhaust gas was passed through a heat exchanger in contact with water to produce steam. The generated steam can be superheated and then introduced to a fluidized bed gasification reactor (catalytic gasifier) supplied with a catalyzed feedstock. The catalyzed feedstock was introduced under a positive pressure of nitrogen. Typical conditions for the catalytic gasifier was a total pressure of 500 psi and temperature of 1200 degrees F. The effluent of the catalytic gasifier containing methane, colon dioxide, hydrogen, carbon monoxide, water, hydrogen sulfide, ammonia and nitrogen, which were passed to a scrubber to remove ammonia and to an acid gas removal unit to remove hydrogen sulfide and carbon dioxide. Then the carbon dioxide was recovered.
