Start-up of a hydrorefining process
Patent
·
OSTI ID:5144480
This paper 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 condition. The improvement comprises: heating the catalyst at initial start-up from a temperature below about 450{degrees}F to hydrorefining temperature at an average rate of less than 10{degrees}F per hour in the presence of hydrogen and the oil feed.
