FORERO, Carmen R. et al. CO2 CAPTURE BY CHEMICAL LOOPING COMBUSTION. Rev.Colomb.Quim. [online]. 2010, vol.39, n.2, pp. 271-285. ISSN 0120-2804.
NiO and CuO based oxygen carriers (OCs) supported on Al2O3 prepared by impregnation were selected for its evaluation in a continuous pilot plant of 500 Wth of two interconnected fluidized beds, where both methane and syngas were used as fuel gas. In addition, the effect of possible impurities in the fuel gas such as sulphur compounds and other hydrocarbons in the combustion efficiency of the process and the behaviour of the OCs were studied. Based on these results, it can be concluded that both OCs are suitable for a chemical looping combustion (CLC) process with methane, syngas and methane with impurities such as light hydrocarbons or sulphur.
