This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/Chemical Looping Combustion (CLC) with solid fuels has been widely developed by using two interconnected fluidized beds, the fuel reactor and the air reactor, with an oxygen carrier continuously circulating between them. Experience gained in this process shows that high CO2 capture values can be reached. However, complete combustion of the fuel is not achieved, with some H2, CO and CH4 as the main unconverted compounds in the combustion products from the fuel reactor. It is believed that the combustion efficiency can be increased by improving the gas-solid contact in the fuel reactor. In this work, the solids distribution in the fuel reactor was modified by using ring-type internals with the objective of enhancing the gas-solid contact. Two experimental campaigns were carried out in a 50 kWth CLC unit burning a bituminous coal with ilmenite particles in the temperature interval of 900–1000 °C. The first campaign was conducted with the original riser of the fuel reactor, which was characterized by a smooth section from bottom to top. For the second campaign, three ring-type internals were implemented in the riser in order to modify the solids distribution in the fuel reactor. The presence of the internals had a beneficial effect on the coal combustion. The major benefit was an improved oxidation of volatile matter in the form of CH4 and the full conversion of H2. As a result, the total oxygen demand decreased by 20%, from 12.2% to 9.8%, with the implementation of the internals.This work was supported by the Ministerio de Economía, Industria y Competitividad (projects ENE2014-56857-R and ENE2016-77982-R), the Spanish National Research Council (CSIC project: 2017-80E035), the Research Fund for Coal and Steel (RFCS project ACCLAIM: RFCP-CT-2012-00006) and the European Regional Development Fund (ERDF).Peer reviewedElsevierConsejo Superior de Investigaciones Científicas (España)European CommissionMinisterio de Economía, Industria y Competitividad (España)Pérez-Vega, Raúl [0000-0001-7600-9704]Abad Secades, Alberto [0000-0002-4995-3473]García Labiano, Francisco [0000-0002-5857-0976]Gayán Sanz, Pilar [0000-0002-6584-5878]Diego Poza, Luis F. de [0000-0002-4106-3441]Adánez Elorza, Juan [0000-0002-6287-098X]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]201920192019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/181418reponame:DIGITAL.CSIC.
