Abstract: A system for treating non-petroleum or renewable feedstocks containing oxygen and contaminants of one or more of metals, gums, and resins comprises a reactor having a heat source for heating an interior of the reactor. The reactor is configured to receive the feedstock at a flow velocity of from 20 ft/sec to 100 ft/sec within the interior to facilitate heating the feedstock to a temperature of from 700° F. to 1100° F. to form a reactor product. A heat exchanger is configured to cool the reactor product and a separator unit is configured to separate metals, water, and gases comprising C1 or greater hydrocarbons from the cooled reactor product to form a final product. A reformer unit is configured to receive at least a portion of the gases for converting the at least one of C1 or greater hydrocarbons to produce hydrogen gas from the C1 or greater hydrocarbons.

Abstract: A system and method for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor having a pyrolysis conduit and a solids return conduit segment. Each segment is configured with an outlet and an inlet to receive and discharge solid materials that are circulated through the reactor through the different segments. A solids conveyor is disposed within the pyrolysis conduit segment to facilitate conveying solid materials from the solids inlet upward through the pyrolysis conduit segment toward the solids discharge outlet. A pyrolysis feedstock is introduced into the pyrolysis reactor and at least a portion of the feedstock is converted to pyrolysis gases within the pyrolysis conduit segment, which are discharged through a gas outlet. An eductor condenser unit with an eductor assembly having a venturi-restricted flow path for receives a pressurized coolant fluid. A second flow path for receiving the discharged pyrolysis gases intersects the venturi-restricted flow path so that the received pyrolysis gases are combined with the coolant fluid and are discharged together to a mixing chamber that is used to condense pyrolysis gases.

Abstract: A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.

Abstract: A system that includes a feedstock of a non-petroleum or renewable feedstock containing oxygen and contaminants of one or more of metals, gums, and resins that is introduced into the 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 one or more of gums and resins in the fats and/or oils of the feedstock. The system further includes a reactor product that is formed in the reactor from the feedstock that has the one or more of gums and resins in the fats and/or oils of the feedstock removed and/or reduced and a heat exchanger to cool the reactor product. A separator unit separates and removes non-condensable gases, metals and water from the cooled reactor product. A final product of the system is separated from the non-condensable gases, metals and water from the cooled reactor 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 of any triglycerides, monoglycerides, diglycerides, free fatty acids, phosphatides, sterols, tocopherols, tocotrienols, and 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 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.

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 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.
