    Abstract: A non-petroleum or renewable feedstock containing oxygen and contaminants of metals, gums, and resins is treated by introducing the feedstock into a reactor at a flow velocity of from 20 ft/sec to 100 ft/sec. The feedstock is heated within the reactor to a temperature of from 700° F. to 1100° F. to remove and/or reduce the content of the contaminants to form a reactor product. The reactor product is cooled to form a cooled reactor product. Non-condensable gases, metals and water are separated and removed from the cooled reactor product to form a final product. The final product has an oxygen content that is 60% or less of that of the feedstock, and wherein the final product comprises 25 wt % or less any triglycerides, monoglycerides, diglycerides, free fatty acids, phosphatides, sterols, tocopherols, tocotrienols, or fatty alcohols, from 5 wt % to 30 wt % naphtha, and 50 wt % or more diesel.

    Abstract: A method of hydroprocessing is performed wherein non-petroleum feedstocks, such as those containing from about 10% or more olefinic compounds or heteroatom contaminants by weight, 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. The reaction products are cooled and/or water is removed from the reaction products. At least a portion of the cooled and/or separated reaction product are introduced as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst. The feed and hydrogen are allowed to react in a liquid phase within the second reaction zone to produce a second-reaction-zone reaction product.

    Abstract: A system for treating non-petroleum or renewable feedstocks comprises a reactor having a heat source for heating an interior of the reactor. The reactor receives a feedstock of a non-petroleum or renewable feedstock containing oxygen or contaminants at certain conditions to form a reactor product having gums and resins of the feedstock removed and/or reduced. A first heat exchanger cools at least a portion of the reactor product to a reduced temperature to form a reduced-temperature reactor product. A hydroprocessing reactor receives at least a portion of the reduced-temperature reactor product to form a hydroprocessed product. A second heat exchanger receives the hydroprocessed product to cool the hydroprocessed product to a temperature of 250° F. or less to form a cooled hydroprocessed product. A separator is configured to separate and remove non-condensable gases, metals and water from the cooled hydroprocessed product to form liquid hydrocarbons that form a final product.

    Abstract: In a method of hydroprocessing, hydrogen gas for the hydroprocessing reaction is combined with a liquid feed composition comprising a feedstock to be treated and a diluent to form a feed stream, at least a portion of the hydrogen gas being dissolved in the liquid feed composition of the feed stream, with non-dissolved hydrogen gas being present in the feed stream in an amount of from 1 to 70 SCF/bbl of the liquid feed composition. The feed stream is contacted with a hydroprocessing catalyst, within a reactor while maintaining a liquid mass flux within the reactor of at least 5000 lb/hr·ft2 to form a hydroprocessed product.

    Abstract: A method of treating non-petroleum or renewable feedstock is carried out by introducing a non-petroleum or renewable feedstock containing gums and/or resins into a reactor at a flow velocity of from 20 ft/sec to 100 ft/sec. The feedstock is heated within the reactor to a temperature of from 700° F. to 1100° F. to convert the feedstock to a reactor product. The reactor product is cooled to form a cooled reactor product. Gases, metals, and water from the cooled reactor product are separated and removed to form a final product. The final product has a gum or resin content that is reduced by 10 wt % to 100 wt % by weight of the initial gum and resin content of the feedstock.
