Use of hopcalite derived Cu-Mn mixed oxide as oxygen carrier for Chemical Looping with Oxygen Uncoupling Process

Chemical-Looping with Oxygen Uncoupling (CLOU) is an alternative Chemical Looping process for the combustion of solid fuels with inherent CO2 capture. The CLOU process needs a material as oxygen carrier with the ability to give gaseous O2 at suitable temperatures for solid fuel combustion, e.g. copp...

The CLOU process needs a material as oxygen carrier with the ability to give gaseous O2 at suitable temperatures for solid fuel combustion, e.g. copper oxide and manganese oxide. In this work, treated commercial Carulite 300® was evaluated as oxygen carrier for CLOU. Carulite 300® is a hopcalite material composed of 29.2 wt.% CuO and 67.4 wt.% Mn2O3. Oxygen release rate and the fluidization behavior, regarding agglomeration and attrition rate, were analyzed in a TGA and in a batch fluidized bed respectively. Experiments in a batch fluidized bed reactor were carried out at temperatures ranging from 800 to 930 ºC with a medium volatile bituminous coal from South Africa and its char as fuels.

This material has the capacity to generate gaseous oxygen at lower temperatures than Cu-based oxygen carriers, which suggest this material is suitable to work at lower temperatures in the fuel reactor without the presence of unburnt products; however its low mechanical resistance after redox cycles makes necessary an improvement of its physical properties for being use as an oxygen carrier.This work was partially supported by the Spanish Ministry of Economy and Competitiveness (MINECO Project: ENE2013-45454-R) and the European Union FEDER funds.Peer reviewedAmerican Chemical SocietyMinisterio de Economía y Competitividad (España)European CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201720172016info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/157391reponame:DIGITAL.CSIC.
