Abstract
The invention provides a method for the production of a supported nickel catalyst, in which an aqueous mixture comprising an alkali metal salt plus other metal salts is sintered to form a support material. A supported nickel catalyst comprising potassium β-alumina is also provided.
Claims7
A supported nickel catalyst precursor obtained via a method comprising the steps of:
- a. providing a mixture comprising:
- i. magnesium mineral or magnesium salt,
- ii. optionally, a calcium mineral or calcium salt,
- iii. an aluminium mineral or aluminium salt,
- iv. an alkali metal salt comprising at least one of Na and K, and
- v. optionally water;
- b. extruding said mixture to form an extrudate, said extrudate containing integrated reservoirs of said alkali metal salt, and calcining the extrudate at a temperature from 300-600° C.;
- c. sintering said calcined extrudate at a temperature in a range of 1100-1400° C. to form a support material;
- d. impregnating said support material with an aqueous solution comprising a nickel salt to provide the supported nickel catalyst precursor;
- and
- e. optionally repeating step d.
A supported nickel catalyst comprising nickel supported on a support material, characterised in that said support material comprises potassium β-alumina or sodium β-alumina, or mixtures thereof.
A steam reforming process comprising the steps of:
- i. providing a supported nickel catalyst comprising nickel supported on a support material, characterised in that said support material comprises potassium β-alumina or sodium β-alumina, or mixtures thereof;
- ii. passing a hydrocarbon fuel over said supported nickel catalyst in the presence of steam so as to produce syngas.
