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.
Claims7
A method for the conversion of synthesis gas, which comprises a mixture of gaseous carbon oxides and hydrogen, to alcoholic products and hydrocarbons whereby water gas shift activity is increased, which comprises passing said synthesis gas at conversion conditions over a catayst comprising an effective amount of alumina and a metal cyano cuprate having the formula:
- A.sub.x B.sub.y [Cu(CN).sub.4 ]
- where the charge on the [Cu(CN).sub.4 ] anion of said cuprate is -3;
- where A and B are the same or different and are selected from the group consisting of zinc, iron, cobalt, nickel, ruthenium, thorium, rhodium, zirconium, hafnium, chromium, iridium, osmium, copper, rhenium, tungsten, titanium, manganese, molybdenum, lanthanum, cerium, uranium, hydrogen, sodium, potassium, rubidium, cesium, magnesium, calcium, strontium, and barium;
- and where x multiplied by the valence state of A plus y multiplied by the valence state of B equals +3.
