Effect of support on reactivity and selectivity of Ni- based oxygen carriers for Chemical-Looping Combustion
نویسندگان
چکیده
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

Reduction 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 کاملChemical-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...
متن کاملEffect of Fuel Gas Composition in Chemical-Looping Combustion with Ni-Based Oxygen Carriers. Part 1. Fate of Sulfur
Chemical-Looping Combustion (CLC) has been suggested among the best alternatives to reduce the economic cost of CO2 capture using fuel gas because CO2 is inherently separated in the process. As gaseous fuels it can be used natural gas, refinery gas or syngas from coal gasification, which may 2 contain different amounts of sulfur compounds, such as H2S and COS. An experimental investigation of t...
متن کاملMapping of the Range of Operational Conditions for Cu-, Fe-, and Ni- based Oxygen Carriers in Chemical-Looping Combustion
Chemical-Looping Combustion (CLC) is a two-step combustion process that produces a pure CO2 stream, ready for compression and sequestration. A CLC system is composed by two reactors, an air and a fuel reactor, and an oxygen carrier circulating between the reactors, which transfers the oxygen necessary for the fuel combustion from the air to the fuel. This system can be designed similar to a cir...
