1,198,991. Making fuel gas. GAS COUNCIL. 22 Sept., 1967 [22 June, 1966; 22 Feb., 1967], Nos. 27930/66 and 8447/67. Heading C5E. The subject-matter of this specification is substantially the same as that described in Specification 1,196,413, but the second stage reforming catalyst is any suitable material, e.g. one described in Specifications 953,877 and 966,883, except nickel-uranium, which may however be employed for the fist stage reformer.
