چکیده

• Validation of optimum operating conditions for a Cu-based oxygen carrier. Very low air excess may be used in chemical looping combustion. Complete CH 4 conversion is achieved. Negligible copper loss due to migration the surface particles. Excellent mechanical performance Chemical combustion (CLC) allows fuel with inherent CO 2 capture by using an carrier transfer from fuel. Previously CLC scale-up, tests should done lab-scale units determine promising carriers, and at same time, evaluate durability these materials. For that, effect on ageing considered, which often disregarded. In this work, were burning simulated biogas stream continuous 500 W th unit (Cu14Al_ICB). Operating carefully selected maximize while complete was These based limiting both variation solids choosing suitable circulation rates oxidation degree particles reactor minimizing excess. Thus, Cu14Al_ICB material exhibited excellent resistance, estimating particle lifetime 20000 hours 900 °C. addition, not relevant. This first time that under certain conditions, can exhibit outstanding properties during operation

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...

Solid waste management of a chemical-looping combustion plant using Cu-based oxygen carriers.

Waste management generated from a Chemical-Looping Combustion (CLC) plant using copper-based materials is analyzed by two ways: the recovery and recycling of the used material and the disposal of the waste. A copper recovery process coupled to the CLC plant is proposed to avoid the loss of active material generated by elutriation from the system. Solid residues obtained from a 10 kWth CLC proto...

Chemical-Looping Combustion and Gasification of Coals and Oxygen Carrier Development: A Brief Review

Chemical-looping technology is one of the promising CO2 capture technologies. It generates a CO2 enriched flue gas, which will greatly benefit CO2 capture, utilization or sequestration. Both chemical-looping combustion (CLC) and chemical-looping gasification (CLG) have the potential to be used to generate power, chemicals, and liquid fuels. Chemical-looping is an oxygen transporting process usi...

Chemical 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)....
