Nitrogen-containing metal oxide pre-catalyst for the direct conversion of co2 to fuel range hydrocarbons

Abstract

A method of making a catalyst comprises dissolving one or more metal salts in water to form a solution, wherein the metal salts comprise one or more of copper, potassium, iron, manganese, cobalt, palladium, silver, lanthanum, vanadium, chromium, gadolinium, gallium, zinc, nickel, or niobium; adding a nitrogen-containing precipitating reagent to the solution until the solution has a pH of about 6.5; separating solids from the solution to obtain the pre-catalyst; calcining the solids at a temperature between 350° C. and 900° C. to obtain calcined solids; and exposing the calcined solids to CO2 and H2 under reaction conditions, to form the catalyst. The catalyst can be used in a method to convert CO2 to hydrocarbons by reacting CO2 and H2 at a reaction temperature, a reaction pressure, and a reaction gas hourly space velocity (GHSV); thereby obtaining hydrocarbons.
