CATALYST PREPARATION METHOD

摘要

A method is described for preparing a catalyst comprising the steps of: (i)impregnating a calcined support comprising a metal aluminate with a solution comprising nickel acetate at a temperature = 40°C and drying the impregnated support, (ii)calcining the dried impregnated support, to form nickel oxide on the surface of the support and (iii)optionally repeating steps (i) and (ii) on the nickel oxide coated support. The method provides an eggshell catalyst in which the metal oxide is concentrated in an outer layer on the support.
