Title:
液体または固体のハロゲン化炭化水素を還元的脱ハロゲン化するための方法
Document Type and Number:
Japanese Patent JP5138838
Kind Code:
B2
Abstract:
1. Process for the reductive dehalogenation of liquid or solid halogenated hydrocarbons.2.1 Toxic liquid or solid halogenated hydrocarbons such as DDT, HCH, in particular halogenated aromatics such as TCB, PCB, PCP and PCDD/PCDF as such or as contaminants in waste oil or contaminated soil or soil like materials can, in most cases, not at all be dehalogenated or, at best, on a very lavish scale. According to the present invention said halogenated hydrocarbons can be dehalogenated without any problems.2.2 This can be achieved according to the present invention through transforming the halogenated hydrocarbons as such and the contaminated material respectively into a finely dispersed solid formulation and heating said formulation for a short time with finely dispersed reducing metals.2.3 Hence, it is for the first time that practice-relevant problems with toxic halogenated hydrocarbons can be solved, in particular with respect to the dehalogenation and thus detoxification of halogenated hydrocarbons in heterogeneous systems, for instance in wet oil, sludge and soil.
