1. A method of hydroprocessing comprising:
(a) introducing a non-petroleum feed to be treated along with a diluent and hydrogen, wherein the type and amount of diluent added is set so that all of the hydrogen is available in solution, into a first reaction zone containing a hydroprocessing catalyst, and optionally performing at least one of (A) and (B) wherein:
(A) is adjusting the amount of diluent combined with the non-petroleum feed to maintain the temperature within the reactor below a preselected temperature and
(B) is adjusting the amount of diluent combined with the non-petroleum feed to adjust the capacity of the liquid phase to dissolve or carry water and/or hydrogen;
(b) 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 remaining in the liquid phase;
(c) separating any gases from the liquid phase reaction products; and
(d) reforming at least a portion of the separated gases from (c) comprising at least one of C1 or greater hydrocarbons to form hydrogen gas.
