CO2 hydrogenation to methanol at pressures up to 950bar

Abstract The methanol synthesis from CO 2 hydrogenation is of great interest because it offers a way to mitigate the anthropogenic CO 2 emissions and gives the opportunity to produce methanol from renewable and recyclable feedstock. Methanol is a key component in the chemical industry and can serve as fuel. In this work the high pressure approach of the transformation of CO 2 to methanol is investigated based on the energy balance for the production of 1 Mt methanol per year from air-captured CO 2 and hydrogen from water electrolysis. The energy efficiency is almost pressure independent and is comparable to literature values. The energy consumption for the compression of CO 2 and H 2 accounts only for 26% of the total energy consumption. Experimental investigations of the CO 2 hydrogenation at 950 bar show up to 15 times larger methanol space time yields (STY methanol ) compared to literature values where CO 2 was hydrogenated to methanol at 30 bar.
