Abstract: A supercritical hydrocyclotron for transforming one or more selected polymeric materials into a plurality of reaction products via supercritical or near-supercritical water reaction that enable the rapid and economic conversion of solid biomass and/or waste plastic materials (i.e., organic materials) into smaller liquid and gaseous hydrocarbon molecules—smaller hydrocarbon molecules that, in turn, are useful as chemical feedstock materials including, for example, liquid transportation fuels and bio-adhesives. The innovative supercritical hydrocyclonic systems and related mobile units disclosed herein comprise, in combination, (1) a supercritical water (or near-supercritical water) treatment system for converting organic materials into smaller hydrocarbon molecules, and (2) a hydrocyclonic separation system for recovering the smaller hydrocarbon molecules from the combined water/hydrocarbon effluent.

Abstract: A process to produce a light hydrocarbon fraction from a heavy residue feed, the process comprising the steps of operating the first supercritical reactor such that the heavy residue feed and the supercritical water stream undergo conversion reactions to produce a reactor effluent, introducing the reactor effluent to a top inlet in a top portion of a second supercritical reactor, introducing a supercritical water stream to a bottom inlet in a bottom portion of the second supercritical reactor, operating the second supercritical reactor such that the bottom of the barrel fraction is configured to settle in the bottom portion of the second supercritical reactor, withdrawing an upgraded product stream from a top outlet in the top portion of the second supercritical reactor, and withdrawing a heavy product stream from a bottom outlet in the bottom portion of the second supercritical reactor.

Abstract: A process for the preparation of ethylene homopolymers or copolymers in a facility having a high-pressure tubular reactor and a preheater, wherein a reaction fluid introduced into the reactor at a reactor inlet is heated in the preheater and the average velocity of the reaction fluid in the preheater is lower than the average velocity of the reaction fluid in the tubular reactor and the ratio of the average velocity in the tubular reactor to the average velocity of the reaction fluid in the preheater is in the range from 1.5 to 5.

Abstract: Compositions, methods, devices, and systems for purifying a source liquid from a replenishment stock solution that includes stabilizing agents, such as metal ions, prior to vaporization. Certain embodiments effect the purification with a solid perfluoronated ionomer, such as a perfluoronated ionomer membrane. Advantageously, source liquids purified in this manner provide feed stocks for production of ultra-pure gaseous reagents. As well, performance characteristics of membrane-based vaporizers relying on transport processes are improved.
