Abstract
The invention relates to an improved method of presulfurizing a sulfidable metal oxide(s)-containing catalyst which minimizes sulfur stripping upon start-up of a reactor and improves catalyst activity. The method consists of contacting a sulfidable metal oxide(s)-containing catalyst with elemental sulfur at a temperature such that said elemental sulfur is substantially incorporated in the pores of said catalyst by sublimation and/or melting and heating the sulfur-incorporated catalyst in the presence of a liquid olefinic hydrocarbon at a temperature greater than about 150.degree. C.
