Zusammenfassung:	1471589 Hydrodesulphurization of oils BRITISH PETROLEUM CO Ltd 9 Oct 1975 [24 Oct 1974] 45995/74 Heading C5E [Also in Division B1] Hydrocarbon feedstocks are desulphurized with H 2 in the presence of a catalyst comprising 1-50 wt. per cent of a hexagonal disulphide of a Group VIA metal (e.g. molybdenum disulphide) and a graphite-containing carbon having a basal plane surface area of at least 100 m.2/g., a ratio of BET surface area to basal plane surface area of at most 5 : 1 and a ratio of basal plane surface area to edge surface area of at least 5 : 1. The catalysts may also contain an iron-group (e.g. cobalt) component. The conversion conditions may be 150-500 C., 5-250 bars g., LHSV of 1-20, and H 2 flow rate 20- 2000 m.3/m.3 Examples describe the formation of a mixture of butane and butene by the hydrodesulphurization of thiophen.
