Thermochemical conversion of biomass volatiles via chemical looping: Comparison of ilmenite and steel converter waste materials as oxygen carriers
نویسندگان
چکیده
Two oxygen carriers were tested with respect to chemical looping combustion (CLC) and gasification (CLG). Ilmenite, a natural ore composed mainly of iron–titanium oxide, LD Slag, an iron-based industrial waste, investigated at 850 900 °C in continuous operation 0.3 kW chemical-looping reactor system using synthetic biomass volatiles as fuel. CLC CLG conditions simulated the fuel by changing flow rates. In case ilmenite syngas yield methane conversion increased rate. Consequently, hydrocarbon ratio was higher for ilmenite. Methane improved both increasing operating temperature. Oxygen release observed Slag. The H2/CO between 0.7 0.8 flows. With CLC, showed gas than slag. Analysis particles revealed that possessed better mechanical properties formed less dust compared Slag during

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...
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 کاملBiomass for thermochemical conversion: targets and challenges
Bioenergy will be one component of a suite of alternatives to fossil fuels. Effective conversion of biomass to energy will require the careful pairing of advanced conversion technologies with biomass feedstocks optimized for the purpose. Lignocellulosic biomass can be converted to useful energy products via two distinct pathways: enzymatic or thermochemical conversion. The thermochemical pathwa...
