Abstract
Hydrocarbons and especially as gasoline are prepared by the catalytic conversion in two subsequent reactors of a synthesis gas containing hydrogen and carbon oxides and having a mole ratio CO/H.sub.2 above 1 and when the conversion commences a mole ratio CO/CO.sub.2 of 5 to 20. In the first reactor, which is preferably a cooled reactor, the synthesis gas is converted into a methane-containing first intermediate and this at least partly further into a second intermediate containing dimethyl ether, at 5-100 bar and 150.degree.-400.degree. C., in the presence of catalyst(s), the effluent from this reactor is combined with a recycle stream containing low boiling components of the effluent from the second reactor, and then passed to the second reactor, which is adiabatic, where the conversion of the second intermediate is carried out at substantially the same pressure as in the first reactor and 150.degree.-600.degree. C. in the presence of a catalyst, preferably a zeolite catalyst, converting said intermediate partly into hydrocarbons, preferably hydrocarbons that are liquid at NTP conditions.
