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...

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...

Chemical looping combustion (CLC) has unique potential for avoiding the large costs and energy penalties of existing CO2 capture technologies. Oxygen is transferred to fuel using an oxygen carrier, thus contact between air fuel. Consequently, products, H2O, come in a separate stream, more or less pure obtained after condensation H2O. CLC normally conceived as dual fluidized bed process, with hi...

This article reviews the progress made in CO2 separation and capture research and engineering. Various technologies, such as absorption, adsorption, and membrane separation, are thoroughly discussed. New concepts such as chemical-looping combustion and hydrate-based separation are also introduced briefly. Future directions are suggested. Sequestration methods, such as forestation, ocean fertili...
