The organic matter super criticality hydrothermal reaction treatment manner and the reaction process which

摘要

PROBLEM TO BE SOLVED: To improve separability of solid liq. and gas content by a method wherein hydrothermal reaction of a substance to be treated is perform and reaction treated substances formed are separated into an inorg. content and a liq. content by means of separator and the liq. content is continuously discharged by a discharging means under connected condition with the separator while the inorg. content is removed. ;SOLUTION: In a hydrothermal reaction treatment plant X, after a liq. org. substance (a) to be treated is heated by a preheater 2 to a temp. before supercritical condition, supercritical hydrothermal reaction is generated by a supercritical hydrothermal reaction treating means 3A. Reaction treated substances formed by the supercritical hydrothermal reaction are subjected to evacuation in separators 4B and 4C and inorg. substances in the supercritical water are deposited and accumulated on the inner bottom parts of the separators 4B and 4C. By passing a supercritical product through a particle filling layer, the inorg. content is absorbed on the particle filling layer and only the filtrate is discharged from the separators 4B and 4C. Inorg. substances separated and deposited or accumulated by the separators 4A-4C are transferred into a discharging means 5 by opening a control valve (c) between the discharging means 5.;COPYRIGHT: (C)1999,JPO
