Definitions
- the basic standard method of calculating exhaust gases is based on the use of a single standard function.
- the mentioned catalytic methods are not universal; they contain active, non-hazardous, and non-hazardous equipment.

- Combustible gases suggest the optional introduction of carbon-containing or termed reactants and solvents and the use of modifier layers is used.
- a well-known complicating factor in calculating combustible gases from 5 is a high concentration of water vapor (6-10%).
- the remaining nitrous gases are formed from acids, from nitrous oxides, it is easily decomposed and 1/3 of 2 is absorbed Particularly lightweight, this runs on 0 refrigerated feed paths for the catalytic converter.
- the proposed method in order to avoid this phenomenon and for a more complete pressure reduction, it is available in the form of a gaseous gas that is inaccessible to Then they neutralize the acidic 5 residues and the absorbed oxides by the consumables that are owned by the owners that are immune to the accidents caused by the accidents.

- the commercial units comprised 20-30 wt.% Of the catalyst (100-150 g / l) introduced into the media of the carrier together with the U binder of the vacuum.
