<p>1. A method for the catalytic gas purification of industrial waste gases in stationary devices by means of catalytic conversion of undesired components on a solid metallic or oxidic catalyst having a source of heat which is arranged in the center part of the catalyst body, characterized in that the flow of gas to be purified passes the catalyst bed periodically in two different directions, the gas flow direction being changed at a frequency of from 1 to 120 times per hour, preferably 10 to 20 times per hour, and the source of heat necessary for the start and for the maintenance of the catalytic conversion reaction is located directly in the catalyst bed, layers of ceramic or metallic profiles being mounted in front of and behind the catalyst bed which accumulate the heat in the time intervals between the successive changes of direction of the gas flow through the reactor.</p> |
