Abstract: Disclosed is a method of continuously preparing N,N-Bis(2,2,6,6-tetramethyl-4-piperidyl)-1,6-hexamethylenediamine, which relates to chemical engineering. The Pt/C catalyst and the quartz sand are mixed uniformly and loaded to the continuous-flow fixed-bed reactor. Then, hydrogen gas and a substrate solution containing 2,2,6,6-tetramethyl-4-piperidinone and 1,6-hexanediamine are simultaneously fed to the micro-mixer and the continuous-flow fixed-bed reactor in sequence to undergo a continuous catalytic reductive amination to obtain the N,N-Bis(2,2,6,6-tetramethyl-4-piperidyl)-1,6-hexamethylenediamine.

Abstract: A system for post-processing carbon powders includes a fluidized-bed reactor having an interior containing a fluidized-bed region. The system may include a gas feed source, a gas inlet value, a gas-solid separator, and an energy source coupled to the fluidized-bed reactor. Carbon nano-particulates may be loaded, in powder form, into the fluidized-bed region prior to operation. The gas feed source may output a gas-phase mixture into the interior of the fluidized-bed reactor, and the energy source may electromagnetically excite the gas-phase mixture and generate a plasma-phase mixture formed in a plasma region positioned adjacent to or within the interior of the fluidized-bed reactor. The energy source may be positioned at one or more positions relative to the gas inlet valve.

Abstract: A chemical solution synthesis device comprises a chemical solution holding unit, a reaction vessel, a first chemical solution feed unit, a chemical solution feed and discharge unit, and a second chemical solution feed unit. The chemical solution holding unit is configured to hold a chemical solution. The chemical solution and carriers are reacted in the reaction vessel. The chemical solution is transferable from the chemical solution holding unit to the reaction vessel without coming into contact with atmosphere. The first chemical solution feed unit is connected to the reaction vessel and configured to supply the chemical solution to the reaction vessel. The chemical solution feed and discharge unit is provided vertically above the first chemical solution feed unit. The second chemical solution feed unit is configured to suppress adhesion of the carriers to the reaction vessel.

Abstract: A continuous falling film reactor includes a reactor body including chambers for a reaction between first and second reagents. The chambers have a respective inner surface, for the sliding of the first reagent in the form of a thin film, or layer, a device for introducing the first reagent, in particular in the liquid phase, especially in the form of an organic raw material, into the respective chamber and a device for inputting the second reagent, in particular in the gaseous phase, especially in the form of sulphuric anhydride, in the respective one of the chambers. A head introduces the first reagent, in the respective chamber, which head—includes a corresponding nozzle so calibrated to cause a predetermined load loss of said first reagent.
