TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The sorbent comprises CaO.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The subjecting the feedstock to fast pyrolysis hydropyrolysis comprises hydropyrolysis. The method further involves regenerating the sorbent by heating through combustion of the char and any coke deposited on the sorbent or catalyst, or regenerating the sorbent by heating with superheated steam. The method further involves regenerating or decoking the catalyst in regeneration step; regenerating or decoking the catalyst in regeneration step. The product hydrocarbon is methane, and where converting at least a portion of the pyrolysis gas includes a methanation step. In the method, the converting at least a portion of the pyrolysis gas occurs at a temperature of 500-650 degrees C, and at a pressure of 1-50 bara. In the method, regenerating the sorbent occurs at temperature of 700-850 degrees C. The separating hydrogen comprises pressure swing adsorption; and membrane permeation. The method further involves providing the catalyst in any of the following reactor configurations so that the catalyst will cycle between distinct reaction zones for hydroconversion and regeneration steps: moving bed with granular catalyst; fixed bed with granular packing or monolithic catalyst, and rotary or directional valve logic for cyclically switching beds between reaction and regeneration steps; bubbling or circulating fluidized bed. The method further involves providing staged reactors for hydropyrolysis and hydroconversion steps; performing. hydropyrolysis and hydroconversion steps in a single bubbling fluidized bed reactor. The hydroconversion is performed to produce liquid hydrocarbons, and a sorption enhanced reaction step is performed to generate hydrogen required for the hydroconversion step. The liquid hydrocarbons are produced as first product of heavier hydrocarbons and second product of gasoline range hydrocarbons. The product methane is also produced in hydroconversion step with sorption enhanced reaction. The method further involves generating electrical power with an internal-reforming solid oxide fuel cell fuelled by methane and hydrogen converted from the biomass feedstock. In the method, the substantially the entire anode exhaust of the solid oxide fuel cell is provided as the source of hydrogen and steam to hydropyrolysis step or hydroconversion step. The method further involves generating power with a gas turbine to recover heat from regenerating the sorbent. Preferred System: In the system, the fast pyrolysis units includes hydrogen sweep gas. The portion of the hydrogen is produced in a steam reforming zone. In the system, the hydrocarbons converted over the catalyst are mainly methane, and the catalyst is in methanation zone. The catalyst used in the steam reforming and methanation zones is the same catalyst. The steam reforming and methanation zones are combined within a hydroconversion reactor. The system further comprises regeneration units for heating and regenerating the catalyst in a regeneration zone; units for cyclically circulating or switching the catalyst between the hydroconversion and regeneration zones. The catalyst is supported in fixed beds with switching valves to establish the hydroconversion and regeneration zones to which each bed is cycled. The fixed beds containing the catalyst are mounted in a rotor with rotary valve ports sealingly engaged with fixed ports to establish the hydroconversion and regeneration zones to which each bed is cycled. All of the hydrogen is produced in the steam reforming zone or hydroconversion reactor. EXAMPLE - No suitable example given.
