Description
  • Toluene alkylation with propylene and 1-octene was investigated over a number of different zeolites (ZSM-5, ZSM-11, ZSM-12, Beta, Mordenite, zeolite Y), mesoporous molecular sieves (Al)MCM-41, and micro/mesoporous composites. It was shown that the acid strength of acid sites plays an important role in the activation of olefin for the alkylation reaction. The highest conversion in all alkylation reactions were obtained over zeolites exhibiting a high concentration of Broensted acid sites. However, in the case of toluene alkylation with propylene tha structure of some zeolites induced the formation of undesired n-propyltoluene as a side product. (Al)MCM-41 exhibited lower toluene conversions due to the absence of strong acid Broensted sites, however, the formation of di-alkyl toluenes was substantially limited due to a lower activity of this catalyst.

  • Alkylace toluenu propylenem a 1-oktenem byla studována na různých typech zeolitů, mesoporézních molekulových sít a kompozitních materiálů. Byla prokázána klíčová role silně kyselých aktivních center pro aktivaci olefinu. Nejvyšší aktivity byly dosaženy u zeolitů s nejvyšší koncentrací Broenstedovských kyselých center. V případě některých zeolitů dochází také k tvorbě nežádoucího n-propyltoluenu. Nízká kyselost mesoporézních sít (Al)MCM-41 zapříčinila jejich malou katalytickou aktivitu a také nízkou selektivitu na více alkylované tolueny. (cs)
