Document Type and Number:
Japanese Patent JP4344458
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for preventing the corrosion of a supercritical apparatus, capable of economically preventing the corrosion of the inner wall surface of a reaction container. SOLUTION: A powdery particulate of inorganic matter containing SiO2, Al2O3, CaO and Fe2O3 is sent in the reaction container 1 for decomposing waste by a supercritical water oxidizing method to be reacted at 200-500 deg.C and to form a coating layer 6 of an inorganic oxide hard to corrode on the wall surface of the reaction container 1. It is unnecessary to disassemble the reaction container 1 and initial cost and running cost are reduced.
