The growing concern about global warming and climatechange has driven many countries to take action and generate new policies for environmental protection. Among human activities which generate greenhouse gases (GHG), energy production accounts for around 75% of the total shares[1]. As 90% of the energy-related emissions derived from theoxidation of carbon, CO2 is considered the largest source ofGHG in this category. Strategies like low carbon-energy production have been raised. Between these technologies, hydrogen production through reforming of bioethanol is an interesting alternative due to the low cost and high disponibility of bioethanol, their easy handling and storage, etc. In thiscontext, Ni and Co based-catalysts have been proposed ascost-effective catalysts. The ethanol reforming process canbe intensified by in situ CO2 secuestration in the Sorption Enhanced Steam Reforming of Ethanol (SESRE), which couldyield higher concentrations of H2 [2]. For this purpose, combinations of catalysts+CO2 sorbents as well as bifunctionalcatalysts have been proposed. Therefore, this contributionpresents a preliminary study of the SESRE reaction using acombination of a Ni-ZrO2 catalyst and a Li2ZrO3-basedsorbent. The solids were preparated by wet impregnationand characterized by XRD and Raman Spectroscoy. CO2 capture tests were performed for the sorbent, while for theevaluation of the SESRE reaction, a mixutre of catalyst+sorbent was employed
