Abstract: Synthesis gas is converted to valuable hydrocarbon or alcohol products over catalysts comprising metal cyanide complexes which have been activated by treatment with a reducing gas. The metal cyanide catalysts of this invention, when compared to prior art catalysts, demonstrate increased water gas shift activity such that more oxygen is rejected from the process as CO.sub.2 rather than H.sub.2 O, thus improving the economics of the synthesis gas conversion process.

Abstract: A method and sequence of process steps is described for effecting the conversion of lower alcohols comprising methanol, ethanol and propanol to gasoline boiling range component arranged to significantly extract reaction heat and selectively control the restricting of the alcohol feed through the production of ethers and olefins prior to isomerizing and aromatizing the formed olefins. A tubular reactor section is particularly relied upon for the highly exothermic olefin forming step of the combination operation.

Abstract: The conversion of methanol to gasoline boiling hydrocarbons in a thermally balanced operation with a special group of zeolite catalysts having a constraint index of 1 to 12, a silica to alumina ratio of at least about 12 and a crystal density of not substantially lower than about 1.6 grams per cubic centimeter is described. The steady state operation of the process is improved by feeding methanol preheated to a selected temperature proximate to its boiling point so that the heat required thereafter to vaporize the feed and to raise its temperature to conversion temperature is substantially equal to the exothermicity of the conversion itself.
