Hydrothermal reaction treatment apparatus and hydrothermal reaction treatment method

摘要

PROBLEM TO BE SOLVED: To improve the efficiency of hydrothermal reaction treatment in a hydrothermal reaction treatment device. A hydrothermal reaction treatment device (10) covers a pressure vessel (12) as a reaction vessel for performing a hydrothermal reaction by heating and pressurizing a liquid to be treated containing a reaction target and water, and covering the pressure vessel with a molten salt. The molten salt layer 24 to be formed and the heating unit 26 for heating the molten salt layer 24 to melt the molten salt are provided. [Selection diagram] Figure 1
