Abstract
The present invention relates generally to ultradispersed catalyst compositions and methods for preparing such catalysts. In particular, the invention provides catalyst composition of the general formula: BxMyS[(1.1 to 4.6)y+(0.5 to 4)x] where B is a group VIIIB non-noble metal and M is a group VI B metal and 0.05≦y/x≦15.
Claims7
A catalyst composition of the general formula:
- BxM1yM2zO(2 to 3)zS[(0.3 to 2)y+(0.5 to 4)x]
- where B is a group VIIIB non-noble metal and M1 and M2 are group VI B metals and 0.05≦y/x≦15 and 1≦z/x≦14
- and wherein the catalyst composition is an ultradispersed suspension in a hydrocarbon solvent with a median particle diameter from 30 nm to 6000 nm.
