Fibrous silica zinc oxide-supported nickel catalyst for dry reforming of methane and methods of preparation thereof

Abstract

A method for dry reformation of methane (DRM) includes introducing a H2-containing feed gas stream into a reactor, including a nickel-containing fibrous silica zinc oxide (Ni/FSZ) catalyst, passing the H2-containing feed gas stream through the reactor to contact the H2-containing feed gas stream with particles of the Ni/FSZ catalyst at a temperature of from 500 to 900 degrees Celsius (° C.) to form a reduced catalyst; terminating the introduction of the H2-containing feed gas stream and introducing and passing a mixed feed gas stream including CH4 and CO2 through the reactor to contact the mixed feed gas stream with the reduced catalyst at a temperature of from 500 to 1000° C. thereby converting at least a portion of the CH4 and CO2 to H2 and CO; and regenerating the Ni/FSZ catalyst particles to form a regenerated catalyst and producing a residue gas stream leaving the reactor.
