    Abstract: Exemplary chemical looping systems include at least one type of active solid particles and inert solid particles that may be provided between various reactors in exemplary systems. Certain chemical looping systems may include a reducer reactor in fluid communication with a combustor reactor. Some chemical looping systems may additionally include an oxidizer reactor in fluid communication with the combustor reactor and the reducer reactor. Generally, active solid particles are capable of cycling between a reduction reaction and an oxidation reaction. Generally, inert solid particles are not reactants in either the reduction reaction or the oxidation reaction.

    Abstract: It is the aim of the present invention to provide a process and a system for the gasification and/or combustion of biomass and/or coal with an at least partial carbon dioxide separation enabling an effective gasification as well as an un-expensive and effective separation of carbon dioxide thereby achieving a long-term stability of the materials used in the process. These objectives are achieved by a process for the gasification and/or combustion of biomass and/or coal with an at least partial carbon dioxide separation using a combined combustion/gasification reactor (2) having a combustion part (6) and a gasification part (4), comprising the steps of: a) feeding the coal and/or feeding biomass into the gasification part (4) of the combustion/gasification reactor (2); b) in the gasification part (4), optionally under a feed of water or water vapour, heating and optionally pressuring the coal and/or the biomass at an elevated temperature and at an optionally elevated pressure in order to generate a product gas (8); c) filtering the product gas (8) to separate ash, soot and other solid particles from the product gas (8); d) feeding the filtered product gas (8')and an oxidized bed material (20) into the combustion part (6) of the combustion/gasification reactor (2); e) in the combustion part (6), at least partially reducing the oxidized bed material (20) in order to generate heat that is being transferred partially into the gasification part (4); f) leading the exhaust gas (16) of the combustion part (6) to a turbine or a heat exchanger or into a further combustion reactor (18) or a catalytic conversion and leading the at least partially reduced bed material (22) into an oxidation reactor (24) fed with air (26) in order to re-oxidize the bed material prior to its recirculation into the combustion part (6).

    Abstract: Various aspects provide for a multistage fluidized bed reactor, particularly comprising a volatilization stage and a combustion stage. The gas phases above the bed solids in the respective stages are separated by a wall. An opening (e.g., in the wall) provides for transport of the bed solids from the volatilization stage to the combustion stage. Active control of the gas pressure in the two stages may be used to control residence time. Various aspects provide for a fuel stream processing system having a pretreatment reactor, a combustion reactor, and optionally a condensation reactor. The condensation reactor receives a volatiles stream volatilized by the volatilization reactor. The combustion reactor receives a char stream resulting from the removal of the volatiles by the volatilization reactor.
