<p>PROBLEM TO BE SOLVED: To provide an easy-to-operate and practicable batchwise supercritical water reaction apparatus. SOLUTION: This batchwise supercritical water reaction apparatus 10 is the apparatus for treating a hardly pulverizable organic solid by a supercritical water reaction and has a first reactor 12 of a batch type, a continuous second reactor 14 connected in series to the first reactor 12, a water feeding means 16 for feeding the supercritical water to the first reactor 12, an air compressor 18 for feeding air as an oxidizing agent to the first and second reactors, a reaction product outflow system for subjecting the reaction product fluid flowing out of the second reactor 14 to a separation of gas from the liquid and first and second temperature controllers 38 and 40 for controlling the temperatures in the first and second reactors by regulating the feeding flow rate of the air. The first reaction product fluid containing undecomposed matter is further subjected to a supercritical water treatment in the second reactor, by which the complete supercritical water treatment of the hardly pulverizable organic solid is made possible.</p> |
