Catalytic and adsorptive desulphurization of gases

摘要: Abstract The present paper considers some very important problems: problems which are in the area of environmental protection, as well technical and technological desulphurization gases. Here we have selected only those ‘dry’ technologies adsorption catalytic processes occur. presents basics methods for removing sulphur dioxide hydrogen sulphide from what called acid gases, equipment this purpose, together with a discussion advantages disadvantages particular processes. introduction to includes sources emission dioxide, their toxicity, by atmospheric air can be environmentally protected. writer realizes that does not include all but major directions, make removal contamination caused compounds tail gases possible. typical dry conversion represent new direction, is likely undergo intensive development if able solve problem preparation appropriate catalysts operating under difficult unstable conditions.
