Abstract: A method of treating a contaminated oil comprising preparing a brine solution, adding ozone to the brine solution to produce ozonated brine solution, adding a volume of ozonated brine solution to a volume of the contaminated oil, mixing the volumes of contaminated oil and ozonated brine solution with coagulant and surfactant at a shear rate sufficiently high so as to cause formation of an emulsion of the contaminated oil and the brine solution, stopping the mixing, thereby causing the emulsion to separate into an aqueous brine liquid phase and an oil liquid phase, separating the brine liquid phase from the oil liquid phase, and separating at least one contaminant from the oil liquid phase to produce a volume of purified oil.

Abstract: Chemical recycling facilities for processing mixed waste plastic are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy recovery facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

Abstract: The invention relates to a method for preparing core-shell structured particle precursor under a co-precipitation reaction. In this method, by controlling the feeding of different types of anion compositions and/or cation compositions, and adjusting the pH to match with the species, precipitated particles are deposited to form a precipitated particle slurry, filtering, and drying the precipitated particle slurry to yield the particle precursor. The invention also provides a particle precursor which includes a core-shell structure. The shell is made of gradient anions and/or cations. Such particle precursor can be used to prepare cathode of lithium-ion battery.

Abstract: One or more reactants are flowed into thermal contact with a heating element in a reactor for a first time period. During a first part of a heating cycle, the one or more reactants are provided with a first temperature by heating with the heating element, such that one or more thermochemical reactions is initiated. The one or more thermochemical reactions includes pyrolysis, thermolysis, synthesis, hydrogenation, dehydrogenation, hydrogenolysis, or any combination thereof. The first heating element operates by Joule heating and has a porous construction that allows gas to flow therethrough. During a second part of the heating cycle, the one or more reactants are provided with a second temperature less than the first temperature, for example, by de-energizing the heating element. A duration of the first time period is equal to or greater than a duration of the heating cycle, which is less than five seconds.

Abstract: A process includes periodically or continuously introducing an olefin monomer and periodically or continuously introducing a catalyst system or catalyst system components into a reaction mixture within a reaction system, oligomerizing the olefin monomer within the reaction mixture to form an oligomer product, and periodically or continuously discharging a reaction system effluent comprising the oligomer product from the reaction system. The reaction system includes a total reaction mixture volume and a heat exchanged portion of the reaction system comprising a heat exchanged reaction mixture volume and a total heat exchanged surface area providing indirect contact between the reaction mixture and a heat exchange medium. A ratio of the total heat exchanged surface area to the total reaction mixture volume within the reaction system is in a range from 0.75 in−1 to 5 in−1, and an oligomer product discharge rate from the reaction system is between 1.0 (lb)(hr−1)(gal−1) to 6.0 (lb)(hr−1)(gal−1).
