Abstract:
     At least one decomposable compound selected form compourds of group IVB metals is mixed with the feed stream containing hydro carbons. The mixture is then contacted with the hydrofining catalyst. Support of the catalyst is selected from aluminuim oxide, SiO2 and silicone oxide-aluminium oxide. A cocatalyst which contains at least one metal selected from group VIB, VIIB and VIII metals should be added. It is always efficient no matter when the decomposable compound is added to the fresh, partly or wholly deactivated catalyst.
