In a device for preparing process gases () for heat treatments of metallic materials/workpieces, the respective process gas () is to be fed into at least one treatment chamber () in an industrial furnace () having been practically fully prepared, homogenised and heated, and the method is to be carried out both with newly built and particularly with already existing installations of industrial furnaces () with the aid of the device, wherein the process gas () is prepared with compression at temperatures uncoupled from the temperature in the treatment chamber (), in a process separate from the heat treatment process in the treatment chamber (), and in a temperature range up to about 1250° C., and is rendered usable for economical and low-emission heat treatment (FIG. ). 1. A device for carrying out a method for preparing process gases , including{'b': 2', '2', '2', '2', '1', '2', '2', '2', '3, 'a) a closable preparation chamber (.) with catalyst (..) and temperature adjustment device (..) for preparing the process gases (),'}{'b': 1', '4', '2', '3, 'b) a functionally integrated process gas compressor (., .),'}{'b': 2', '4', '3', '1', '3', '2', '3', '1', '1', '2', '2', '1', '4', '2', '3, 'c) equipment (.) for measuring the inflow of treatment media (., .) of the process gas (), the equipment being connected functionally to the treatment chamber (.) of the industrial furnace, to the preparation chamber (.), and to the process gas compressor (., .),'}{'b': 2', '5', '2', '2', '3', '1', '3', '2', '3', '1', '1', '1', '3', '1', '3', '2, 'd) a switching unit (.) for controlling and adjusting at least one of the parameters of the process gas to be prepared in preparation chamber (.) for the purpose of feeding the treatment media (., .), feeding the prepared process gas () into treatment chamber (.) of the industrial furnace (), and the C level, as well as extracting at least one of the treatment media (., .).'}2. The device as recited in claim 1 , characterized by{'b': 2', '2 ...
