Title:
テレフタル酸工程から発生する廃棄物の処理方法
Document Type and Number:
Japanese Patent JP4763789
Kind Code:
B2
Abstract:
Disclosed herein is a method for treating waste byproducts from terephthalic acid processes, by homogeneously mixing the waste byproducts with water and an anti- corrosion agent to prepare a waste water, decomposing organic compounds of the waste water through oxidation reaction with an oxidant under the condition that the waste water is kept in a liquid state, and recovering catalyst particles from the liquid component. The method is of high industrial applicability as it allows organics to be decomposed with the waste byproducts maintained in a liquid state and can recover catalysts with high yield availability.
