<p>PROBLEM TO BE SOLVED: To provide a decomposition reactor having improved efficiency with precisely recognizing the inside environment of a high pressure reaction vessel by monitoring the decomposition reaction and controlling the decomposition reaction according to the inside environment. SOLUTION: In the decomposition device 1 provided with a high pressure reaction vessel 2 for decomposing a material to be treated with water and an oxidizing agent as reaction medium under a supercritical condition, the high pressure reaction vessel 2 is provided with a temperature sensor 10 for detecting the temperature of a fluid (a) present inside, a pressure sensor 9 for detecting the pressure of the fluid (a) and a density sensor 12 for detecting the density of the fluid (a) and further provided with an inside state confirming means capable of confirming the decomposition state inside the high pressure reaction vessel 2 based on the signal detected by the temperature sensor 10, the pressure sensor 9 and the density sensor 12.</p> |
