摘要： A method for spraying starting material particles in a continuous hydrothermal reaction, comprising spraying an aqueous fluid pressurized and heated in excess of the saturated vapor temperature and a starting material slurry pressurized at ordinary temperature. A starting material slurry feed orifice is provided in a central portion of an aqueous fluid spray orifice to spray and mix the aqueous fluid and the staring material slurry. In order to avoid entry of heat into the starting material fluid from the aqueous fluid, a heat-insulating layer is provided between feed paths for the respective two fluids. According to the above method, the starting material slurry is sprayed particularly under subcritical to supercritical conditions beyond the saturated vapor temperature to form fine particles without agglomeration thereof, whereby a hydrothermal reaction can be continuously and efficiently effected.

摘要： A continuous hydrothermal synthesis method which comprises pressurizing and heating a material slurry below a saturated vapor temperature or pressurizing a material slurry at normal temperature, pressurizing and heating an aqueous liquid above the saturated vapor temperature, atomizing and mixing the slurry and the aqueous liquid, effecting hydrothermal synthesis in a reaction section above the saturated vapor temperature, cooling the reaction product and taking out the product while retaining the pressurized state in the system by alternately opening and closing shut-off valves provided above and below a product discharging section or through a thin pipe provided in the product discharging section. The method is performed using an apparatus comprising heating-pressurizing sections respectively connected to a material slurry feeding section and an aqueous liquid feeding section, an atomizing-mixing section and a reaction section provided after these feeding sections, and a product discharging section.
