Patent number: 10618000Abstract: Articles comprising a catalyst film comprising VOx, MoO3 or WO3, and TiO2 deposited on a substrate are disclosed. The articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases. Methods for producing such articles deposit a catalyst film on the substrate to form a coated substrate, which is then calcined. When used in an SCR process, the coated articles have enhanced activity for NOx conversion, reduced activity for SOx conversion, or both. Light-weight, coated articles having high catalyst loads can be fabricated at the same or reduced dimensions when compared with laminated articles, and increased kNOx/kSOx ratios are available even from coated articles having relatively thin catalyst films. The articles should have particular value for power plant operations, where coal and high-sulfur fuels are commonly used and controlling sulfur trioxide generation is critical.Type: GrantFiled: September 1, 2017Date of Patent: April 14, 2020Assignee: Johnson Matthey Public Limited CompanyInventors: Paul Joseph Andersen, Maria Brandmair, Silvia Alcove Clave, Rodney Foo, Bruce Gomersall, Michael Nash, Alison Mary Wagland

Patent number: 10105677Abstract: A method for preparing a sorbent composition includes the steps of: applying, from a solution or a slurry, a layer of a copper compound on the surface of a support material, and drying the coated support material, wherein the thickness of the copper compound layer on the dried support is in the range 1-200 ?m. The precursor may be converted to a sorbent suitable for removing heavy metals from liquids or gases by applying one or more sulphur compounds to sulphide the copper compound and form CuS.Type: GrantFiled: September 15, 2015Date of Patent: October 23, 2018Assignee: Johnson Matthey PLCInventors: Andrew Fish, Lucy Jane Challis, Matthew John Cousins, Mark Robert Feaviour, Alison Mary Wagland, Stephen David Pollington, Edmund Hugh Stitt
