Abstract
Catalytic activities of synthetic zeolite (SiO2/Al2O3=18) – mordenite, modified by metal cations (Pd2+, Ni2+, Co2+, Nd3+, Mo3+, Zr4+, Nb5+) activated under different air stream conditions in the temperature range of 300–4200C in disproportionation reaction of toluene to benzene and xylenes were studied. It was found that synthetic zeolite – mordenite comprising Pd2+, Ni2+ and Nd3+ cations are more active than the catalysts containing Co2+, Mo3+, Zr4+, Nb5+. It has been established that in conditions under study the samples activated in dry-wet air media (by joint yield of toulene and xylene) display the most activity and selectivity
