Description
  • Transport of reactants in porous polyolefin particles is important both in polymerization reactors and in degassing units where the unreacted volatile species have to be removed from freshly produced powder. Degassing characteristics of polyolefin powders at various conditions were determined gravimetrically and were used for estimation of effective transport properties. We also attempt to use the results of degassing measurements for estimation of geometrical parameters of the model of porous polyolefin particle considering two characteristic diffusion lengths: (i) in the pore phase and (ii) in the polymer phase.

  • Transport reaktantů porézními částicemi polyolefinů je důležitý jak v polymerizačních reaktorech tak i v odplyňovacích procesech, kde je nutno odstranit nezreagované těkavé složky z čerstvě vyrobeného prášku polymeru. Odplyňovací charakteristiky polyolefinových prášků byly získány gravimetricky za různých podmínek a byly použity pro odhad efektivních transportních vlastností porézních částic. Příspěvek se také pokouší využít výsledky odplyňovacích měření pro odhad strukturních parametrů porézních částic polyolefinů a uvažuje dvě charakteristické difúzní délky: (i) v pórech a (ii) v polymeru.
