Abstract:
1. A method of hydroprocessing comprising: (a) introducing a non-petroleum feed to be treated containing from about 10% or more by total weight of feed of at least one of olefinic compounds and heteroatom contaminants along with hydrogen into a first reaction zone containing a hydroprocessing catalyst; (b) allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products; (c) removing the reaction products from the first reaction zone; (d) cooling the removed reaction products; (e) introducing at least a portion of the cooled reaction products as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst; (f) allowing the introduced reaction products and hydrogen to react in a liquid phase within the second reaction zone to produce reaction products; (g) removing the reaction products produced in (f) from the second reaction zone; (h) cooling the removed reaction products from (g); (i) combining at least one of (1) a further portion of the cooled reaction product of step (d) and (2) at least a portion of the cooled reaction products of step (h) with at least one of the feeds of step (a) and step (e); and (j) repeating steps (e) through (h) and optionally (i) for any additional reaction zones, as necessary, to provide a final reaction product.
