摘要

•The existence of K2CO3 improved the Ru dispersion in Ru/KMg catal-sorbents.•CO2 capture and methanation temperatures were confirmed.•CO2 capture was conducted in the presence of 10 vol% CO2 and 10 vol% H2O.•The catal-sorbent exhibited a high CH4 yield in integrated CO2 capture and methanation.•Ru/KMg catal-sorbent exhibited stable CO2 capture capacity and CH4 productivity.
