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 C5-C8-olefins in addition to saturated and olefinically, diolefinically and acetylenically unsaturated hydrocarbons in the same boiling range, simultaneously with one or more C1-C4-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 DEG to 180 DEG 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. |
