1. A treated sulfided hydroconversion catalyst, wherein the treated sulfided hydroconversion catalyst comprises 2 wt % to 15 wt % carbon produced from carbonation and is prepared by the following steps:
(a) combining an inactive hydroconversion catalyst with a solid hydrocarbon containing material having a melting point of 50° C. or greater to produce an unsulfided hydroconversion catalyst/solid hydrocarbon containing material mixture; and
(b) sulfiding the inactive hydroconversion catalyst by contacting the unsulfided hydroconversion catalyst/solid hydrocarbon containing material mixture with a gaseous stream comprising hydrogen (H2) and a sulfur-containing compound at a temperature sufficient to sulfide the inactive hydroconversion catalyst and carbonize at least a portion of the solid hydrocarbon containing material on the sulfided inactive hydroconversion catalyst, thereby providing a treated sulfided hydroconversion catalyst further comprising the solid hydrocarbon containing material wherein at least a portion of the solid hydrocarbon containing material is carbonized.
