Syngas combustion in a 500 Wth Chemical-Looping Combustion system using an impregnated Cu-based oxygen carrier
Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherently to the process and thus no energy is expended for the separation. For its use with coal as fuel in power plants, a process integrated by coal gasification and CLC would have important advantages for CO2 capture. This paper presents the combu...
متن کاملReduction Kinetics of Cu-, Ni-, and Fe-based Oxygen Carriers Using Syngas (CO+H2) for Chemical-Looping Combustion
The reactivity of three Cu-, Fe-, and Ni-based oxygen carriers to be used in a chemical-looping combustion (CLC) system using syngas as fuel has been analyzed. The oxygen carriers exhibited high reactivity during reduction with fuel gases present in syngas (H2 and CO), with average values in the range 8-30 % min. No effect of the gas products (H2O, CO2) on the reduction reaction rate was detect...
متن کاملEffect of support on reactivity and selectivity of Ni- based oxygen carriers for Chemical-Looping Combustion
Different Ni-based oxygen carriers were prepared by dry impregnation using -Al2O3 as support. The reactivity, selectivity during methane combustion, attrition rate and agglomeration behaviour of the oxygen carriers were measured and analyzed in a termogravimetric analyzer and in a batch fluidized bed during multicycle reductionoxidation tests. * Manuscript
متن کاملChemical looping combustion process in fixed - bed reactors using ilmenite as oxygen carrier
A process scheme based on a series of fixed-bed reactors is presented as a possible alternative for carrying out the chemical looping combustion of methane at high pressure with ilmenite as oxygen carrier. The oxygen carrier is stationary and it is alternately exposed to reducing and oxidizing atmospheres by means of the periodic switching of the gas feeds (i.e., methane and air, respectively)....
متن کاملA Polygeneration System Based on Multi-Input Chemical Looping Combustion
This paper proposes a polygeneration system based on a multi-input chemical looping combustion system, which generates methanol and electricity, through the use of natural gas and coal. In this system, the chemical looping hydrogen (CLH) production system and the coal-based methanol production system are integrated. A high quality fuel, natural gas, is used to improve the conversion ratio of co...
