  • Patent number: 11673123
    Abstract: Pyrochlore-based solid mixed oxide materials suitable for use in catalysing a hydrocarbon reforming reaction are disclosed, as well as methods of preparing the materials, and their uses in hydrocarbon reforming processes. The materials contain a catalytic quantity of inexpensive nickel and exhibit catalytic properties in dry reforming reactions that are comparable—if not better—than those observed using expensive noble metal-containing catalysts. Moreover, the Pyrochlore-based solid mixed oxide materials can be used in low temperature dry reforming reactions, where other catalysts would become deactivated due to coking. Accordingly, the catalytic materials represent a sizeable development in the industrial-scale reforming of hydrocarbons.

  • Publication number: 20210261407
    Abstract: The disclosure provides a method of producing hydrogen. The method comprises conducting a thermochemical reaction by contacting a metal, or an alloy thereof, with steam to produce a metal oxide and/or a metal hydroxide and hydrogen. The method then comprises contacting the metal oxide and/or the metal hydroxide produced in the thermochemical reaction with water or a basic aqueous solution to produce a solution comprising a metal ion. Finally, the method comprises conducting an electrochemical reaction by applying a voltage across an anode and a cathode, whereby at least a portion of the cathode contacts the solution comprising the metal ion, to produce hydrogen, oxygen and the metal, or the alloy thereof.

  • Patent number: 9834844
    Abstract: A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The streams of heated gases exit through a pair of linear exhausts which are located on either side of an aerospike. The streams converge outside the nozzle and powdered coating material is introduced into the converging streams immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.

  • Publication number: 20170335441
    Abstract: A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The stream of heated gases exits through an annular exhaust which is located around an aerospike. The stream converges outside the nozzle and powdered coating material is introduced into the converging stream immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.
