RT Conference Proceedings T1 Composition-activity relationship for Ni-Alkali/Alkaline earth metal unsupported catalysts in the CO2–SR technology. A1 Essounani-Mérida, Sofía A1 Molina-Ramírez, Sergio A1 Cortés-Reyes, Marina A1 Herrera-Delgado, María Concepción A1 Larrubia-Vargas, María Ángeles A1 Alemany-Arrebola, Luis José K1 Catalizadores AB onCO2-SR technology is a cyclic process that combines the capture and storage of CO2with its conversion to high-value compounds through catalyst regeneration with CH4 [1]. Thisprocess involves the use of a dual function catalyst that contains components for CO2adsorption based on alkali and alkaline earth metals, as well as redox metal components forCO2 conversion. This contribution presents the experimental results of the incorporation ofBa, Ca, Sr and K to Ni as unsupported bimetallic catalytic systems, to analyze the structuraland physicochemical properties and the effect on the CO2 storage and regeneration capacity.
