Abstract: Synthesis gas (a mixture of hydrogen gas and carbon monoxide) is converted to hydrocarbons by flowing the gas first over iron-containing Fischer-Tropsch catalyst and then over a zeolite. The Fischer-Tropsch catalyst contains relatively little nitrogen as a result of its preparation by continuous precipitation at a pH ranging from about 6.6 to 6.9 and a temperature ranging from about 80.degree. to about 100.degree. C.

Abstract: A new catalyst and process for synthesis of dimethyl ether from low H.sub.2 /CO ratio syngas are disclosed. The catalyst is a combination of Cu, Zn and Al, co-precipitated in predetermined relative amounts, which is found to be oxidatively regenerable and utilizable with the syngas product of modern coal gasifiers without the need for external water-gas-shift.

Abstract: Process for preparing caprolactam from cyclohexanone oxime by passing the oxime, preferably dissolved in a solvent, over a zeolite having a SiO.sub.2 /Al.sub.2 O.sub.3 of at least 12 and a Constraint Index of from 1 to 12.

Abstract: Fuel for satisfying low, normal and high electric power generation requirements is obtained from coal in the form of syngas and dimethyl ether fired in turbine-compressor arrangements driving electric generators, wherein the storable ether fuel is fired in turbine-generator arrangements to supplement that normally produced by firing and expanding syngas in appropriate turbine-generator arrangements. High pressure steam generated in the process is expanded in steam turbines to also generate power. Steam product of the combination operation is used in the coal gasification step to produce additional syngas.

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: Conversion of lower alcohols or their corresponding ethers or halides alone or in admixture to conjunct mixtures of hydrocarbon products by catalyzing the conversion with a molten salt bath of zinc chloride with or without potassium chloride with cofed hydrogen.
