Carbon Dioxide Hydrogenation to Produce Fuels Using Petroleum Refinery Facilities

Abstract

A process for direct or indirect hydrogenation of CO2 to produce fuels and fuel components utilizing existing downstream facilities used to produce oil and gas, for example petroleum refineries, is provided. The hydrogenation process typically uses CO2 separated from a source at the petroleum refinery and also low carbon intensity (CI) hydrogen. The process is able to produce low carbon-intensity gasoline, diesel, sustainable aviation fuel, and/or other low carbon intensity fuel components. Gases generated from the hydrogenation step can be recycled and re-used in the hydrogenation process. An aqueous phase produced from the hydrogenation step can be disposed of using an existing water treatment plant at the refinery.
