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 the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor for producing pyrolysis products from the pyrolysis feedstock to be pyrolyzed. An eductor condenser unit in fluid communication with the pyrolysis reactor is used to condense pyrolysis gases. The eductor condenser unit has an eductor assembly having an eductor body that defines a first flow path with a venturi restriction disposed therein for receiving a pressurized coolant fluid and a second flow path for receiving pyrolysis gases from the pyrolysis reactor. The second flow path intersects the first flow path so that the received pyrolysis gases are combined with the coolant fluid. The eductor body has a discharge to allow the combined coolant fluid and pyrolysis gases to be discharged together from the eductor. A mixing chamber in fluid communication with the discharge of the eductor to facilitates mixing of the combined coolant fluid and pyrolysis gases, wherein at least a portion of the pyrolysis gases are condensed within the mixing chamber.

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 at least 20 ft/sec. The feedstock is heated within the reactor and cooled to form a reduced-temperature reactor product. At least a portion of the reduced-temperature reactor product is feed into a hydroprocessing reactor containing a hydroprocessing catalyst to form a hydroprocessed product. The hydroprocessed product is cooled and non-condensable gases, metals and water are separated and removed 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 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 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.

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.
