Combined oxides of iron, manganese and silica as oxygen carriers for chemical-looping combustion

Copper-manganese mixed oxides: CO2-selectivity, stable, and cyclic performance for chemical looping combustion of methane.

Chemical looping combustion (CLC) is a key technology for oxy-fuel combustion with inherent separation of CO2 from a flue gas, in which oxygen is derived from a solid oxygen carrier. Multi-cycle CLC performance and the product selectivity towards CO2 formation were achieved using mixed oxide of Cu and Mn (CuMn2O4) (Fd3[combining macron]m, a = b = c = 0.83 nm) as an oxygen carrier. CuMn2O4 was p...

Effect 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

Effect of pressure on the behavior of Copper-, Iron-and Nickel-based Oxygen Carriers for Chemical-Looping Combustion

Effect of gas composition in Chemical-Looping Combustion with copper based oxygen carriers: Fate of sulphur

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
