Popis:	Transformation of low molecular weight alkanes to alkenes and aromatics via oxidative and non-oxidative routes presents a major challenge since the implementation of the “Cyclar” process. Catalysts containing ZSM-5 zeolite modified with Ga or Zn species were investigated widely for this purpose [1]. Recently other zeolites (faujasite, ferrierite, Beta) were studied in the title reaction [2,3]. We showed that the already few gallium ions accommodated by the faujasite matrix significantly increase the selectivity to propene [2]. Preliminary results on zeolite Beta modified with Ga- and B-species [3] have also shown that this structure possesses promising activity and selectivity in the oxidative dehydrogenation (ODH) of propane.
