STEAM REFORMING CATALYST AND METHOD OF MAKING THEREOF

摘要

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.

1. A method for the production of a supported nickel catalyst precursor, said method comprising the steps of:
i. providing a mixture comprising:
i. a 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, andv. optionally water; ii. extruding said mixture and calcining the extrudate at a temperature from 300-600° C. iii. sintering said calcined mixture at a temperature of between 1100-1400° C. to form a support material; iv. impregnation of said support material with an aqueous solution comprising a nickel salt to provide a supported nickel catalyst precursor; v. optionally repeating step iv.
