Indirect CO₂ Methanation: Hydrogenolysis of Cyclic Carbonates Catalyzed by Ru‐Modified Zeolite Produces Methane and Diols

Abstract

We report ar uthenium-modified zeolite which efficiently transforms propylene carbonate to propylene glycol and methane,under solvent-free conditions.The catalyst achieved high product selectivity and no significant ageing effect was observed after multiple cycles.T he resulting liquid product (water-containing glycol) can be directly used as antifreeze solution and the gas phase can directly be used as an energy carrier in the form of H 2 -enriched methane.T his process efficiently bridges energy storage and an important chemical synthesis under sustainable (CO 2 consuming) conditions.
