ABSTRACT:
This invention relates to a method and apparatus for detecting changes in the composition of a stream of gas. In particular the method comprises the step of disposing a thermometer in the gas stream, in contact with or downstream of a catalyst so as to detect changes in the temperature of the catalyst or of the gas shortly after it leaves the catalyst, such changes being a function of the amount of gas which reacts under the influence of the catalyst.
