METHOD FOR PREPARING IRON-BASED CATALYST AND IRON-BASED CATALYST PREPARED THEREBY

摘要

The present invention relates to a method for preparing an iron-based catalyst, comprising: a precipitate formation step of forming a precipitate by mixing a first solution comprising an aqueous solution containing at least one of iron ore microparticles, copper, cobalt, manganese, nickel, ruthenium, rhodium, rhenium, iridium, platinum or gold nitrate, and an iron nitrate aqueous solution, and a second solution comprising an oxide of at least one of silicon oxide, aluminum oxide, zirconium oxide or chromium oxide, or a precursor thereof, and at least one of an alkali metal carbonate aqueous solution, an alkaline earth metal carbonate aqueous solution or an ammonium aqueous solution; and a sintering step of drying and sintering the precipitate.
