摘要： High-octane, low-olefin motor fuels and motor fuel components having a content of alkyl tert.-alkyl ethers can be produced by reacting a crude hydrocarbon stream, which contains tertiary C.sub.5 -C.sub.8 -olefins in addition to saturated and olefinically, diolefinically and acetylenically unsaturated hydrocarbons in the same boiling range, simultaneously with one or more C.sub.1 -C.sub.4 -alkanols in a quantity from 0.5 to 5 mol per mol of the tertiary olefin(s) and with excess hydrogen relative to the total unsaturation under a pressure from 12 to 80 bar and at a temperature from 60.degree. to 180.degree. C. on a catalyst known per se or a mixture of catalysts known per se, which effect(s) both the etherification and the olefin hydrogenation.

摘要： Unsaturated hydrocarbons and mixtures in which the latter are present are treated with anion exchangers prior to hydrogenation and are then hydrogenated catalytically in a known manner. The treatment with anion exchangers is carried out at 0.degree.-120.degree. C. and at a space velocity of 0.1 to 10 l of hydrocarbons to be hydrogenated per l of exchanger, per hour. The process avoids other, energy-intensive pretreatments, for example distillation of the hydrocarbons to be hydrogenated, or washing, and can be carried out in simple equipment. A considerable prolongation of the catalyst operating time is achieved in the subsequent catalytic hydrogenation.
