Abstract
Steam reforming catalyst having good sinter and polymer resistance and which include a Group VIII metal such as nickel and alumina, have in their calcined but unreduced precursor form pore size distributions defined in the following relationships: PA1 (i) at least 55% of the pore volume of pores having a pore radius between 12 and 120 Angstrom Units is in the range 12-30 Angstrom Units, and PA1 (ii) the ratio of the pore volume contained in pores of 10-50 A to the pore volume contained in pores of 50-300 A is at least 5:1. These catalysts are prepared by coprecipitation at temperatures of not greater than 60.degree. C. wherein a solution of an alkali precipitating agent is added to a solution of the catalytic components.
