Abstract
Desulfurization catalyst comprising an iron group metal and a Group VIB metal is modified by refluxing with an aqueous solution of an alkali or alkaline earth metal, or a transition metal. The pore size distribution of the catalyst is improved.
Claims1
A method for preparing a catalyst, suitable for the hydrodesulphurisation of hydrocarbons, comprising from 1-10% weight of an iron group metal and from 5-25% weight of a Group VIB metal on a refractory support, the method comprising the step of refluxing the catalyst with an aqueous solution of a salt selected from the group consisting of alkali metals salts, alkaline earth metal salts, rare earth metal salts and transition metal salts, and drying and calcining the treated catalyst.
