Abstract: A continuous reaction system (CRS) allows a method to prepare quantum dots (QDs) in a continuous manner with high precision. The CRS pumps a plurality of reagent fluids into one or more mixing sites to form a reaction fluid that is carried through a heating chamber at elevated pressures to carry out hydrothermal growth of the QDs. The pumps and heating chamber are controlled with a high precision by employing a detector downstream of the heating chamber to provide a signal that is dependent on the composition and size of the QDs. The signal is provided to a signal processor that provides a signal that control the flow rates and temperature parameters in the system. The QDs produced in this manner are consistent in size and composition and can be of a single semiconductor composition or can be core-shell QDs with a shell semiconductor formed on a core semiconductor.

Abstract: Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. The reactor system may include a reactor vessel configured to receive a reactor fluid through a reactor fluid inlet and a product source fluid corrosive to portions of the reactor system through a product source fluid inlet. The product source fluid may react with the reactor fluid to produce one or more reaction products, such as a fuel gas. The product source fluid inlet may be arranged within the reactor fluid inlet such that the product source fluid entering the reactor vessel is encased by a fluid conduit formed by the flow of reactor fluid entering the reactor vessel. The layer may operate to reduce corrosion by forming a barrier between the product source fluid and the surface of the reactor fluid inlet and/or the reactor vessel.

Abstract: The present invention provides a production method of polyvinyl chloride by suspension polymerization and a feeding apparatus. This method comprises: Step 1: injecting a vinyl chloride monomer and water at 25-98° C. into a reaction vessel to obtain a water suspension, closing the reaction kettle, repeatedly and cyclically performing vacuum-pumping and cleansing with nitrogen, stirring and evacuating oxygen in the reaction kettle; Step 2: adding a first suspension agent and a second suspension agent into the reaction kettle, and then adding a nanopowder and an initiator composite, to carry out the polymerization reaction; Step 3: adding cold water to terminate the polymerization reaction upon the pressure in the reaction kettle is reduced to 3.5 bar or less; Step 4: evacuating and vacuumizing the reaction kettle, and then filtering, washing and drying the resulted polymer, to obtain polyvinyl chloride. The present invention also provides a feeding apparatus used for the above production method. Polyvinyl chloride produced by the method of this invention has good performance and can meet the requirements of physical and chemical properties and applicability for most applications.

Abstract: Disclosed is a process for the integrated production of urea and melamine. A urea production zone produces a urea synthesis stream comprising urea, water and ammonium carbamate. This stream is subjected to processing, preferably involving stripping, so as to separate an aqueous urea stream from residual dissociated carbamate vapor comprising ammonia, carbon dioxide, and water. The urea is fed to a melamine synthesis zone and subjected to melamine forming conditions so as to form melamine and off-gas comprising carbon dioxide and ammonia. The dissociated carbamate vapor and the melamine off-gas are subjected to combined condensation so as to form a dilute melamine off-gas condensate.
