<p><P>PROBLEM TO BE SOLVED: To provide a method for a hydrothermal reaction which can start the reaction in a short time and minimize the amount of wastewater produced by the reaction, and an apparatus for the reaction. <P>SOLUTION: A three-way valve V8 is adjusted, and kerosene 26 is circulated through a combustible circulating passage 25 and pressurized to a pressure higher than that of a reactor 2. Water is pressurized similarly. Kerosene and air are introduced from a fuel introduction passage 13 into a high temperature, high pressure fluid producing apparatus 3 and burned, the produced high temperature, high pressure fluid is supplied to the reactor 2 to heat the reactor 2 preliminarily. Next, three-way valves V8 and V5 are adjusted, and the pressurized kerosene 26 and the pressurized water 27 are supplied to a supply apparatus 11 and then supplied from the supply apparatus 11 to the reactor 2 to be subjected to the hydrothermal reaction of the kerosene. The reactor 2 is further preheated by the reaction heat. When the reactor 2 is heated to a prescribed temperature, a pressurized treatment substance 28 is supplied into the reactor 2 to be subjected to the hydrothermal reaction with water kept in a supercritical or subcritical state. <P>COPYRIGHT: (C)2004,JPO</p> |
