## Abstract

A method of hydroprocessing is performed wherein non-petroleum feedstocks are treated in a first reaction zone to provide reaction products. The process involves introducing the feedstock along with diluents or a recycle and hydrogen in a first reaction zone and allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products, at least some of the reaction products being in a liquid phase. Gases are separated from the liquid phase reaction products. At least a portion of the gases comprising at least one of C1 or greater hydrocarbons are reformed to form hydrogen gas, which may be used as hydrogen gas for the hydroprocessing process or elsewhere.
