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:n nB x M y S [(1.1 to 4.6)y+(0.5 to 4)x] n nwhere B is a group VIIIB non-noble metal and M is a group VI B metal and 0.05≦y/x≦15. |
