Sulfiding of hydrogel derived catalysts
Patent
·
OSTI ID:5117973
This patent describes a process for increasing the desulfurization activity of a hydrotreating catalyst used for hydrotreating sulfur-containing feedstocks at a temperature in the range of from about 440{degrees}F to about 850{degrees}F prepared by incorporating an element selected from the group consisting of nickel, cobalt and mixtures thereof, and a heavy metal selected form the group consisting of molybdenum, tungsten and mixtures thereof, into an alumina hydrogel. It comprises sulfiding the catalyst with a gaseous sulfur compound at a temperature of at least about 900{degrees}F for at least about one hour.
