Patent number: 10851312Abstract: Flash chemical ionizing pyrolysis (FCIP) process. The FCIP includes mixing an iron source material, an alkali or alkaline earth metal chloride source material, an aqueous phase, and an oil component to form a feed emulsion; introducing the feed emulsion into an FCIP reactor at a temperature greater than about 400° C. up to about 600° C., a pressure from 10 to 50 psia and a residence time of 0.1 to 10 seconds, to form an FCIP effluent; and condensing a liquid ionizing pyrolyzate (LIP) from the effluent. The feed emulsion can be free of added solids other than the iron source material, the alkali or alkaline earth metal chloride source material, and any sediment in the oil component.Type: GrantFiled: April 6, 2020Date of Patent: December 1, 2020Assignee: Racional Energy & Environment CompanyInventor: Ramon Perez-Cordova

Patent number: 10611969Abstract: Flash chemical ionizing pyrolysis (FCIP) at 450° C.-600° C. forms liquid ionizing pyrolyzate (LIP) that can be blended in oil feedstock for thermal processes to promote conversion of heavier hydrocarbons to reduce resid/coke yields and/or increase yields of liquid hydrocarbons and isomerates. A front-end refinery process modifies crude oil with LIP for distillation to reduce resid/coke yields and/or increase liquid oil yields. A downstream process modifies a heavy oil stream such as resid with LIP and the LIP-modified stream can be thermally processed to reduce resid/coke yields and/or increase liquid oil yields. FCIP of the LIP blends also improves quality and/or yields of the liquid pyrolyzate product. Finely divided FCIP solids can contain FeCl3 supported on NaCl-treated calcium bentonite. A process for preparing the FCIP solids treats iron with HCl and HNO3 to form acidified FeCl3 of limited solubility, loads the FeCl3 on NaCl-treated bentonite, and heat-treats the material at 400° C.-425° C.Type: GrantFiled: October 25, 2019Date of Patent: April 7, 2020Assignee: Racional Energy & Environment CompanyInventor: Ramon Perez-Cordova
