摘要：
A naphtha hydrorefining process is initiated by contacting an olefinic naphtha feed at hydrorefining conditions including a pressure below about 200 psig, with hydrogen and a catalyst that has been partially deactivated by treating a fresh or a regenerated catalyst with a substantially non-metals containing hydrocarbonaceous oil in the presence of hydrogen under conditions sufficient to decrease the hydrogenation activity of the catalyst.
