The decoupling reactor solves the problem that an existing high-temperature chemical reactor can not be well used for analyzing a multistage in-situ decoupling reaction of a solid carbon-based fuel. The decoupling reactor comprises a reaction pipe main body, a thermocouple side pipe and an instant feeding side pipe, wherein the reaction pipe main body sequentially comprises a lower pipe section, a lower annular space section, a lower porous plate, a reaction section, and an upper pipe section from bottom to top, the thermocouple side pipe and the instant feeding side pipe are arranged at two sides of the reaction section, one end of the thermocouple side pipe is connected with the outer side wall of the reaction section, and one end of the instant feeding side pipe is connected with the outer side wall of the reaction section. The decoupling reactor is used in the field of analysis and testing of a high-temperature chemical reaction.

The invention belongs to the technical field of phase-change materials and preparation thereof, and discloses a monodisperse high-stability inorganic hydrated salt phase-change nanocapsule as well as a preparation method and application thereof. A wall material of the nanocapsule is an organic polymer material such as polymethyl methacrylate and polystyrene, a core material is an inorganic hydrated salt phase change material, and the mass ratio of the core material in the capsule is 20-95%. According to the invention, an in-situ polymerization preparation technology is adopted, a water-based inorganic hydrated salt core material is dispersed in an alkane solvent for emulsification to form a W / O type emulsion with good dispersion stability, and an oil-soluble nanocapsule shell material is added, so that a polymer is enriched on an oil-water interface and is polymerized to form a compact shell which completely coats the core material; and finally obtaining the hydrated salt nano phase change capsule material with the hydrated salt wrapped by the polymer. The hydrated salt nanocapsule disclosed by the invention is high in coating rate, good in dispersion system and stable in performance, and has a good market application prospect.
