متن کاملSimulation and validation of chemical-looping combustion using ASPEN plus
Laboratory-scale experimental studies have demonstrated that Chemical-Looping Combustion (CLC) is an advanced technology which holds great potential for high-efficiency low-cost carbon capture. The generated syngas in CLC is subsequently oxidized to CO2 and H2O by reaction with an oxygen carrier. In this paper, process-level models of CLC are established in ASPEN Plus code for detailed simulati...
متن کاملChemical Looping Reforming – an Efficient Process for the Production of Hydrogen from Coal
A novel Chemical Looping Reforming (CLR) process is proposed in which a highly recyclable iron oxide composite particle is reduced with coal and then oxidized back with steam to generate hydrogen. The reduction of iron oxide with coal results in a mixture of CO2 and H2O in the exhaust stream which after water condensation provides a ready to sequester relatively pure CO2 stream. This eliminates...
متن کاملEnergy analysis of two stage packed-bed chemical looping combustion configurations for integrated gasification combined cycles
Chemical looping combustion is a promising technology for power production with integrated CO2 capture. High overall efficiencies can be reached, if the CLC reactors are operated at elevated pressures and high temperature, which can be accommodated in packed bed reactors. More possible oxygen carriers can be selected if the desired temperature rise for power production is achieved in a two stag...
متن کاملDynamic Model of Single-reactor Chemical Looping Combustion
The paper presents a simplified model of chemical looping combustion in a fixed bed reactor under isothermal condition. Both reduction and regeneration phases of the oxygen carrier are modeled in the single reactor model under the hypothesis of discontinuous feed and simplified reaction kinetics. This model is meant to be the simplest possible formulation for a description that incorporates all...
