Start-up of a hydrorefining process

Patent ·
OSTI ID:5144432
; ;
This patent describes improvement in a hydrorefining process which comprises contacting hydrocarbonaceous oil feed and hydrogen with a catalyst comprising a hydrogenation component selected from the group consisting of Group VIB metal component, Group VIII non-noble metal component and mixtures thereof, and an alumina-containing support, at hydrorefining conditions. The improvement comprises heating the catalyst in substantially non-sulfided form at initial start-up from a temperature below about 450{degrees}F to hydrorefining temperature at an average rate of less than about 10{degrees}F per hour in the presence of hydrogen and a start-up hydrocarbonaceous oil feed having a sulfur content in the form of organosulfides of greater than 0.5 moles (basis elemental sulfur) per kilogram of start-up feed.
