Production of activated charcoal beads for producing adsorbent, especially filter or protective material, comprising continuous carbonization of modified styrene-divinylbenzene polymer beads, batch pyrolysis and activation
Production of activated charcoal beads for producing adsorbent, especially filter or protective material, comprising continuous carbonization of modified styrene-divinylbenzene polymer beads, batch pyrolysis and activation
In the production of activated charcoal beads (I) by low temperature carbonization and activation of polymer beads based on styrene and divinyl benzene containing groups, which form free radicals on thermal decomposition and hence induce cross-linking, especially sulfonic acid (SO3H) groups, low temperature carbonization is started continuously, then pyrolyzed and activated discontinuously. Independent claims are also included for (a) (I) produced as above, especially with an intrinsic surface area of 800-1500, preferably 900-1200 m2/g, diameter of 0.2-1.0, preferably 0.3-0.8 mm, with a root mean square value of 0.4-0.6 mm, a bursting pressure of 5-20 N/bead and/or a jarred density of 400-800, preferably 500-750 g/l; (b) adsorbent materials containing (I), especially filters and protective materials, for the specified uses.
