Catalysts and processes for the direct production of liquid fuels from carbon dioxide and hydrogen

This invention describes a process to convert carbon dioxide and hydrogen into syngas, a mixture of carbon monoxide and hydrogen. It uses two different catalysts in sequence. First, hydrogen and carbon dioxide are fed into a reactor with a specific metal-alumina spinel catalyst to produce syngas, and then a second catalyst further processes the remaining carbon dioxide in that syngas to create even more syngas.
