摘要

A startup method for a process designed to effect the conversion of hydrocarbonaceous black oils. Applicable to a fixed-bed catalytic system, the method involves (1) prewetting the catalyst with a hydrocarbon mixture and (2) low-temperature reduction and sulfiding using circulating (recycle) hydrogen and a sulfurous hydrocarbon mixture.
