Method for ozone decomposition.

摘要

The invention provides a method of deozonizing a waste gas containing ozone as well as nitrogen oxides and/or sulfur oxides, which comprises contacting the waste gas with a filter strucure for nitrogen oxides and sulfur oxides, and then with a deozonizing catalyst structure. In the deozonizing a waste gas containing nitrogen oxides, it is particularly useful to use a filter structure for nitrogen oxides which contains activated carbon as a first adsorbent and at least one of oxides, hydroxides and carbonates of alkali metal or alkaline earth metal. <IMAGE>
