Eta phase materials, methods of producting the same, and use thereof as catalysts for alcohol synthesis, hydrocarbon synthesis, hydrocarbon hydrogenation and hydrocarbon conversion reactions
This patent describes an eta phase composition in powder form, prepared in the absence of sulfur or sulfur bearing compounds, the powder having a surface area greater than about 2m{sup 2}/g and the eta phase consisting essentially of X{sub 6}Y{sub 6}Z{sub a}. It comprises carbides, nitrides, or carbonitrides wherein X is at least one element selected from the group consisting of Mo and W, Y is at least one element selected from the group consisting of Fe, Co, Ni, Mo and W, Z is at least one element selected from the group consisting of C, N and combinations thereof such that when Z is N, a is greater than or equal to 1 but less than or equal to 2 and when Z is C, a is greater than 1 but less than or equal to 2 except when Z is C and Y is Fe, then a is greater than or equal to 1 but less than or equal to 2.
