20200377802 · 2020-12-03 ·

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.
