Abstract

Methane-containing gases are produced by the catalytic-stream-reforming of hydrocarbon feedstocks using a catalyst which includes a Group VIII metal such as nickel and alumina, and which in its calcined but unreduced precursor form has a pore size distribution defined as follows: 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 of 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 50-300 A is at least 5:1.
