One of the most important current objectives of the Chemical Looping Combustion (CLC) technology for gaseous fuels lies in scaling-up the aforementioned technology in the short term from 100 kW(th) to 10 MWth scale. In order to meet this challenge, the commercial availability of suitable multi ton-scale oxygen carrier materials at competitive price is needed. In this work, a Cu-based oxygen carrier prepared by the impregnation method using a commercial alumina as support, referred as Cu14 gamma Al_Commercial, has been developed and evaluated in a 500 W-th CLC pilot plant during the combustion of CH4 at two different temperatures, i.e., 800 degrees C and 900 degrees C. The outstanding results obtained in terms of both combustion efficiency and mechanical stability have shown that the Cu14 gamma Al_Commercial impregnated oxygen carrier can be selected to upscale CLC technology for gaseous fuels.
