Sb. Derouane-abd Hamid et al., Effect of the activation procedure on the performance of Mo/H-MFI catalysts for the non-oxidative conversion of methane to aromatics, CATAL TODAY, 63(2-4), 2000, pp. 461-469
The effect of pre-treatment on the performance of Mo/H-MFI zeolite catalyst
s applied to the non-oxidative conversion of methane to aromatics has been
investigated. It is demonstrated that catalyst performance depends on activ
ation conditions. Activation of the Mo-oxide/H-MFI precursor with an n-buta
ne/hydrogen mixture results in higher catalyst stability and benzene select
ivity which are tentatively attributed to the formation of the alpha -MoC1-
x carbide, with f.c.c. structure as revealed by XRD. (C) 2000 Published by
