초록

Disclosed is a process which comprises calcining an intimate mixture of elemental sulfur and compounds of the other elements in the following empirical atomic formula and further treating the resulting mass to obtain the new catalyst: XYaZbScOd wherein: X is a transition element or a mixture thereof selected from the group V, Mo, W; Y is a stability enhancing element or a mixture thereof selected from the group C, Si, B, Ce, Th, Nb, Zr, Ta, U, where “a”can vary from 0 to 2; Z is a promoter element or a mixture thereof selected from the group Co, Ni, Fe, ...

대표
청구항

A method of making a catalyst comprising forming an intimate mixture of one or more sulfides of one or more of the elements selected from the group consisting of vanadium, molybdenum and tungsten with elemental sulfur, heating the mixture to a temperature in excess of 200°C., contacting the mixture with hydrogen and hydrogen sulfide to produce an exotherm, cooling the resulting mixture and forming it into a catalyst.
