The efforts of the scientific community to tackle the problem around CO2 emissions are intense anddiverse. In this work, the process of CO2 capture and utilization has been implemented in a cyclicway using a lithium silicate (Li/Si=4,1-HW) as a sorbent for CO2 capture at high temperature and ananoparticle Ni (5%) supported on silica mesocellular foam catalyst for CO2 methanation. Threedifferent configurations were employed for the coupling of both materials at 500°C.
