rotary kiln for molecular sieves activation

process for the production of carbon molecular sieves

Mar 12, 1996 · From German Patent 36 18 426 and German Patent 21 19 829 mentioned therein it is known to produce carbon molecular sieves for the separation of gases with small molecular size, particularly O 2 and N2, in the following manner: finely ground hard coal is oxidized with air in a fluidized bed. After adding coal-tar pitch as a binder and water, the coal is molded and carbonized at temperatures up to 900° C., subsequently activated

activated carbon solutions from carbotech | carbotech group

Compared to activation in a rotary kiln, the carbon particles are activated more effectively because we achieve a more uniform structure with larger pores. As a result, our activated carbon offers optimum adsorption, binding pollutants perfectly

the carbonization process and equipment of activated carbon

May 15, 2020 · The carbonization process of activated carbon. 1) Carbonaceous material flow: the shaped particles (raw material) are directly lifted into the charging chamber of the rotary kiln by the conveyor, and fall into the drum by gravity, and are brought to the board along the spiral movement in the drum. Move in the direction of the burner

Process for producing carbon molecular sieves for separating oxygen and nitrogen, consisting of treating a carbonization product having a content of volatile components of up to 5 % with carbon-separating hydrocarbons, which react in the carbon-containing structure of the carbonization product with narrowing of already existing pores. The carbonization product is fed into a vibrating oven at a

industrial zeolite molecular sieves | intechopen

Aug 24, 2016 · After the shaping process, the molecular sieve has to be dried and activated in a thermal step, for example, in a rotary kiln or belt calciner to remove the water and other adsorbed compounds. The applied temperature is often higher than required for the zeolite activation, since the binder system needs such higher temperatures for setting

pyrolysis of waste tyres: a review (journal article

Aug 15, 2013 · Carbon molecular sieves (CMS) have become an increasingly important class of adsorbents for use in gas separation and recovery processes. The overall objective of this project is to determine whether Illinois Basin coal is a suitable feedstock for the production of CMS and to evaluate the potential application of these products in commercial gas separation processes
