  • oxygen-containing gas mixture should be understood in particular to mean air and air enriched or depleted with oxygen
  • Such carburizing and hardening processes of metallic material usually run at high temperatures - preferably in the range from 800 to 1100 ° C. But other heat treatment processes with temperatures above 500 ° C. are also carried out in atmospheres containing CO and H 2 Basis of the catalytic conversion of a hydrocarbon gas (gem ⁇ sch) it with carbon dioxide formed the required treatment gas
  • This reaction is usually accomplished with a gas generator which is arranged next to the one or more heat treatment furnaces or is mounted directly on the furnace housing and consists of a catalyst in the core.

  • the known gas generators for generating reaction or protective gas atmospheres for the heat treatment of metals consist of a highly heat-resistant metallic retort shell into which the catalytically active material is poured in the form of bulk material.
  • the catalyst retort filled in this way is filled from the outside and / or inside by means of appropriate heating devices. or heated and kept at the desired operating temperature with continuous energy supply
  • Such gas generators generate between 8 and 300 Nm 3 / h of reaction gas in industrial heat treatment
  • a disadvantage of the known gas generator designs is that the supply of energy or heat to the catalyst retort is not selective. This leads to certain areas of the catalyst retort being "supplied” with too little energy, while other areas of the catalyst retort may be supplied with too much heat Too little heat, for example, demands the sooting of the catalyst bed - which should be avoided as far as possible - because this at least requires regeneration of the catalyst retort or the entire retort has to be replaced.On the other hand, too much heat increases the wear considerably and reduces the lifespan of the retort and catalytic material

  • At least the first retort area in the flow direction is preferably designed to be removable from the gas generator
  • the catalyst retort or the gas generator can be particularly with strongly endothermic reaction processes with hydrocarbon gases, for. B in the reaction of carbon dioxide and methane to predominantly carbon monoxide and hydrogen, to a faster sooting, so that it is often advantageous if only this area of the catalyst retort is replaced (more frequently)
  • An advantageous embodiment of the gas generator according to the invention is characterized in that at least the first retort area in the flow direction is at least partially filled with a catalytic neutral and / or an at least catalytically reduced effective material
  • Oxide ceramics e.g. aluminum oxide and zirconium oxide

  • the heat is supplied selectively over the length of the catalyst retort and adapted to the needs of the local reaction sequences.
  • the energy or heat supply can thus be adapted to the energy requirements within the catalyst retort - which are based on the composition of the gases to be converted.
  • the means for heating are therefore designed to be variable with regard to the heating power.

  • the gas generator according to the invention consists of a housing 3, which is preferably cylinder-symmetrical, which is divided into four areas 1, 2a, 2b and 2c, as well as a heating device 7, which is not shown in detail in the figure for the sake of clarity.

  • the heating device 3 is delimited from the upper and lower housing edges of the gas generator by insulation 10a and 10b. Furthermore, spacers 5a and 5b between individual retort areas - in the case of the embodiment shown in the figure, these are areas 2b and 2c - and the heating device 7 are to be provided

  • the container 6 which can be removed from the gas generator can consist of a temperature-resistant, purely metallic, ceramic-coated metallic or a purely ceramic material. Both the choice of material for the container 6 and the material 1 arranged in it takes into account a high temperature resistance, a high thermal conductivity and a low one catalytic effect at low temperatures, so that soot formation is inhibited as far as possible
  • the input gas mixture should be supplied via line 9 by suitable insulation in the water-cooled deck ice system 8 such that the cold gas mixture supplied - in which no soot formation occurs - enters a comparatively hot retort area with temperatures above 800 ° C., so that the gas mixture is subjected to heating as quickly as possible area 2a can in turn be built up from a stratification which prevents the formation of very high temperatures above 1100 ° C.
  • Such high temperatures occur in particular in the production of endogas from air and methane (natural gas) in a ratio of about 2.5 to 3.0 by an exothermic partial reaction taking place when the heated starting gas mixture comes into contact with the catalytically active composition. It is therefore advantageous to use a material similar to that in the first retort area 1 directly behind the first catalytically active layer used, built, k build up an inactive or less effective layer with high temperature resistance
  • the composition of the equilibrium of the protective gas which is dependent on the temperature and the mixing ratios of the starting components, is mainly due to the reaction
  • the carbon dioxide content which is important for carbon-active heat treatment atmospheres, it can therefore be advantageous to set the temperature in this last area independently of the previous areas It is therefore expedient to selectively supply the heat over the length of the catalyst retort and in a manner adapted to the needs of the local reaction processes.
  • the retort areas 2a, 2b and 2c can of course also be designed to be removable from the gas generator.
  • soot is significantly reduced due to the provision of catalytically neutral and / or an at least catalytically reduced effective material in the first retort area in the direction of flow.
