Latest Patents

Wei Liu's latest patents include a "Composite catalyst for carbon monoxide and hydrocarbon oxidation" and a "Catalyst for elemental sulfur recovery process." The first patent describes a method and composition for the complete oxidation of carbon monoxide and/or hydrocarbon compounds. This method involves reacting carbon monoxide and/or hydrocarbons with an oxidizing agent in the presence of a metal oxide composite catalyst. The catalyst is prepared by combining fluorite-type oxygen ion conductors with active transition metals. The fluorite oxide is selected from a group that includes cerium oxide, zirconium oxide, thorium oxide, hafnium oxide, and uranium oxide, and may be doped with alkaline earth and rare earth oxides. The transition metals, which serve as additives, include molybdenum, copper, cobalt, manganese, nickel, and silver, with an atomic ratio of transition metal to fluorite oxide being less than one.

The second patent focuses on a catalytic reduction process for the direct recovery of elemental sulfur from various SO₂-containing industrial gas streams. This catalytic process provides high activity and selectivity, as well as stability in the reaction atmosphere, for the reduction of SO₂ to elemental sulfur product using carbon monoxide or other reducing gases. The reaction occurs over a metal oxide composite catalyst characterized by specific empirical formulas.
