Abstract The activity and selectivity of a mechanical Ga2O3/HZSM5 mixture in four model reactions (propane aromatization at 803 K,n-heptane cracking and meta-xylene isomerization at 623 K, methylcyclohexane transformation at 773 K) were compared after pretreatment at 873 K under nitrogen and under hydrogen flow. It was thus demonstrated that the hydrogen treatment provoked a significant increase in the dehydrogenating activity of the gallium species but only a small decrease in the protonic acidity. Moreover this hydrogen treatment created a significant hydrogenolysis activity.
