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

Publication number: 20120136191Abstract: The invention is a method of dehydrogenating a hydrocarbon, especially an alkane, to form an unsaturated compound, especially an alkene, by contacting the alkane with a catalyst comprising a form of carbon which is catalytically active for the dehydrogenation reaction. The catalyst may be formed by passing a hydrocarbon over a metal compound at a temperature greater than 650° C.Type: ApplicationFiled: June 4, 2010Publication date: May 31, 2012Applicants: CAMBRIDGE ENTERPRISE LTD., JOHNSON MATTHEY PLCInventors: Edmund Hugh Stitt, Michael John Watson, Lynn Gladden, James McGregor

Patent number: 6409981Abstract: A process for the scrubbing of chlorine is scrubbed from a chlorine-containing gas using an aqueous feed liquor containing an excess of alkali to give an effluent liquor containing chloride and hypochlorite ions is disclosed. The effluent liquor is recycled as part or all of the aqueous feed liquor. For at least part of the time, at least part of the effluent liquor is passed through a fixed bed of a catalyst for the decomposition of hypochlorite ions whereby hypochlorite ions are decomposed to oxygen gas and chloride ions. The resultant catalyst-treated liquor is mixed with the remainder, if any, of the effluent liquor and recycled, optionally together with added fresh alkali solution, as the aqueous feed liquor. Part of the effluent liquor is optionally discharged as a purge stream before or after passage through catalyst bed.Type: GrantFiled: June 10, 1999Date of Patent: June 25, 2002Assignee: Imperial Chemical Industries PLCInventors: Edmund Hugh Stitt, Frederick Ernest Hancock

Patent number: 6291686Abstract: An exothermic oxidation process wherein a rotating bed containing a variable oxidation state material is cycled through a succession of stages including an oxidative regeneration stage including a step wherein an oxidising fluid is passed through the bed, and a reaction stage wherein feedstock is passed through the bed, whereby said feedstock is oxidised to give products stream with the concurrent reduction of the convertible material to its lower oxidation state. The process can further include a stage wherein cooling fluid is passed through the bed.Type: GrantFiled: March 22, 2000Date of Patent: September 18, 2001Assignee: Imperial Chemical Industries PLCInventors: Samuel David Jackson, Frank King, David Graham Shipley, Edmund Hugh Stitt
