Abstract
Official abstract text for this publication.
The invention relates to a catalyst useful in the steam reforming of hydrocarbons and oxygenated hydrocarbons. The invention provides a method for preparing a catalyst comprising heating a spinel of formula ANixFe(1-X)CrO4 where A is Mn or Mg and x is from 0 to 0.75 under reducing conditions at a temperature of from 800 to 1500° C., and catalysts obtainable by said method.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing a catalyst comprising heating a spinel of formula ANi x Fe( 1−x) CrO 4 where A is Mn or Mg and x is from >0 to 0.75 under reducing conditions at a temperature of from 800 to 1500° C. so as to cause a restructuring of the spinel to form a catalyst comprising a porous spinel phase supporting metal particles of Ni, Fe, mixtures thereof and/or alloys thereof; wherein the porous spinel phase has the formula ANi x Fe (1−x) CrO 4 where A is Mn or Mg and x is 0 to 0.75 or ACr 2 O 4 , where A is Mn or Mg. 2. The method according to claim 1 , wherein the spinel of formula ANi x Fe (1−x) CrO 4 is single phase. 3. The method according to claim 1 , wherein when A is Mn, x is less than or equal to 0.55. 4. The method according to claim 1 , wherein the metal particles have a particle size of 10 nm to 5 μm. 5. A catalyst prepared by the method of claim 1 . 6. A method of steam reforming a hydrocarbon or an oxygenated hydrocarbon comprising contacting said hydrocarbon or oxygenated hydrocarbon with steam and the catalyst according to claim 5 . 7. A method according to claim 6 , wherein said oxygenated hydrocarbon is steam reformed. 8. A method according to claim 6 , wherein said oxygenated hydrocarbon is glycerol.
