A promising approach for chemical energy storage from fluctuating renewable electricity is methanol synthesis from CO2 and hydrogen in a slurry reactor concept, due to efficient heat storage and easy reactor control. In combination with a promising In2O3/ZrO2 catalyst and mineral oil as carrier liquid, efficient methanol production under a wide range of changing process conditions is shown for the first time. A maximum methanol productivity of 2.1 gMeOHgIn−1h−1 and multiple recycling stability of the catalyst and the carrier liquid was achieved, showing no significant decrease in methanol yields.

“…The concept of sorption enhanced catalysis makes use of the fact that the reaction kinetics are controlled by the concentration of reactants and products at the reaction centres, which is modified by active removal of the product. This may be achieved with the help of selective membranes or ionic liquids [9]. Alternatively, the support of the catalyst is replaced by a material being able to adsorb the product(s) to a large extent, e.g., by a zeolite [4,6].…”

Sorption enhanced methanol production makes use of the equilibrium shift of the $$\hbox {CO}_2$$ CO 2 hydrogenation reaction towards the desired products. However, the increased complexity of the catalyst system leads to additional reactions and thus side products such as dimethyl ether, and complicates the analysis of the reaction mechanism. On the other hand, the unusually high concentration of intermediates and products in the sorbent facilitates the use of inelastic neutron scattering (INS) spectroscopy. Despite being a post-mortem method, the INS data revealed the change of the reaction path during sorption catalysis. Concretely, the experiments indicate that the varying water partial pressure due to the adsorption saturation of the zeolite sorbent influences the progress of the reaction steps in which water is involved. Experiments with model catalysts support the INS findings.
