Abstract: [cze] [eng]
V příspěvku jsou shrnuty poznatky z katalytické transformace více-alkylovaných benzenů, katalyzované zeolitickými katalyzátory. Jsou disktovány výsledky kinetického studia přeměny 1,2,4-trimethylbenzenu, toluenu a složek, obsažených v hydrogenačně rafinované C9 pyrolýzní frakci. Dále je posuzována role niklové hydrogenační složky na stabilizaci aktivity daných katalyzátorů. Experiences from catalytic transformation of trialkylbenzenes in reaction with toluene catalyzed by zeolite catalysts were summarized in the study. Kinetic investigation of 1,2,4-trimethylbenzene and tri- and tetramethylbenzenes in hydrorafinated C9 pyrolysis fraction transalkylation by toluene at temperature 350 - 450 oC and hydrogen pressure 3 MPa in bench scale tubular reactor was made. A positive effect of nickel component in catalyst pellet on its stability has been demonstrated. Activity of catalyst prepared in the study was compared with that of commercial sample.
