Crude hydrocarbons with a high sulfur content of up to 1,500 ppm, of which up to 500 ppm are in the form of mercaptans, disulfides or a mixture of both, can be reacted in the presence of a catalyst simultaneously with an alkanol or an alkanediol and hydrogen in such a way that at the same time the etherification of the tertiary olefins, the partial hydrogenation of highly unsaturated compounds and a partial isomerization of the alkenes are carried out if a cation exchanger is used as the catalytic agent which contains SO₃H groups and which, furthermore, is calculated as metal, 0.2- 20 g / l cation exchanger Ni, Pd or a mixture of a metal from a first group of Pd, Ru, Rh and Pt and a metal from a second group of Fe, Co, Ni, Cu, Ag and W, wherein in In the case of a mixture, the metals of the first and second groups are in a weight ratio of 1: 4-4: 1 to one another. |
