Title:

METHOD OF REMOVING ORGANIC HALIDE

Document Type and Number:

WIPO Patent Application WO/1992/011920

Kind Code:

A1

Abstract:

A method of removing a halogenated organic compound such as carbon tetrachloride contained in an amount of about 10 to 10,000 ppm in a waste gas by decomposing the halide through contact with an acidic zeolite, optionally either subjected to ion exchange with metals of the second to sixth periods of the periodic table or supporting these metals thereon. It is possible to remove an organic halide even at a relatively low temperature of 100 to 400 �C and to dispose of also a hydrogen-free organic halide.
