1,153,920. Reforming naphtha. ESSO RESEARCH & ENG. CO. 19 Dec., 1967 [3 Jan., 1967], No. 57624/67. Heading C5E. In a process for catalytically reforming a hydrocarbon feed stream boiling in the motor fuel range and comprising paraffins, naphthenes and aromatics, the hydrocarbon is contacted with a reforming catalyst which comprises a refractory support and a metal component of the platinum group in a reforming zone at reforming conditions, the level of naphthenes is reduced to a maximum of 10% by weight of the feed, and the feed is then contacted with a similar catalyst in sulphided form. There may be three stages, the first two containing unsulphided and the third sulphided catalyst. |
