New selective Mo and NiMo HDS catalysts supported on Al2O3–MgO(x) mixed oxides
107
TL;DR: In this article, the authors showed that even with the incorporation of small amounts of magnesia to the alumina support, the hydrogenation function of the catalyst is substantially reduced and that only the catalysts with low magnesia content ( x =MgO/(mgO+Al 2 O 3 )=0.3 can recover the promotion effect lost by the interaction of NiO with magnesia.

Aromatization over nanosized Ga-containing ZSM-5 zeolites prepared by different methods: Effect of acidity of active Ga species on the catalytic performance
TL;DR: In this article, nanosized Ga isomorphously substituted ZSM-5 zeolite samples (Gax-NZ5) were investigated for the aromatization of 1-hexene and the results indicated that isomorphous substitution promotes the incorporation of Ga heteroatoms into the framework along with the formation of extra-framework GaO+ species.
