Method for predicting the activity of a catalyst and corresponding purification method

摘要

The method involves carrying three measurements of content of pollutant or group of pollutants in fume in a time period of eighteen months, and carrying three tests of activity of a catalyst with regard to another pollutant or another group of pollutants in a time period of eighteen months. A correction function is determined by combining a composite score and the results of the three measurements. Threshold time (t-s) for which content of the pollutant or the groups of target pollutants attains a predetermined threshold value (S) is determined by utilizing the correction function. An independent claim is also included for a method for purifying fume.
