Abstract:
The aromatization of a wide range of model aliphatic and cycloaliphatic hydrocarbons (ethene, ethane, propene, n-hexane, 1-hexene, methylcyclopentane, cyclohexane, cyclohexene) on copper-containing NaZSM-5 and HZSM-5 zeolites has been investigated. It was established that the degree of aromatization is related to carbenium ion formation and depends on the acid strength and copper content of zeolite. Experiments with copper-containing samples reduced prior to use indicated the possibility to enhance the selectivity to aromatization. The change of the state of Cu2+ ions during catalytic experiments confirmed the assumption about participation of Cu0 simultaneously with the Bronsted acid centers in the dehydrogenation/hydrogenation steps.

Abstract:
The Methanol to olefins (MTO) and ethanol to olefins (ETO) reactions were compared under the similar operation conditions, and it was proved that both follow the different reaction mechanism over H-ZSM-5 catalysts. In MTO reaction, dimethyl ether (DME) acts as the initial intermediate, which then follows two different reaction pathways depending on the acidity of H-ZSM-5 catalysts, namely, the dehydration of DME into ethene over higher acidity of H-ZSM-5 catalysts and the merization of DME through hydrogen bonds into (DME)n (n = 2-4) complexes over lower acidity of H-ZSM-5 catalysts. Further, over higher acidity of H-ZSM-5 catalysts, ethene converts into propene and butene, and thereafter undergoes the oligomerization-craking-aromatization route to form other olefins, paraffins and aromatics. But over lower acidity of H-ZSM-5 catalysts, (DME)n complexes tend to transform into high even number of olefins that are easily cracked into small olefins. In the case of ETO reaction, ethene acts as the main reaction intermediate, which then transforms into propene and butene, and further proceeds through the oligomerization-craking-aromatization route to form other olefins, paraffins and aromatics products over H-ZSM-5 catalysts.

Abstract:
Mélanger un oxyde de gallium avec une zéolithe H-ZSM-5 donne les mêmes résultats catalytiques en craquage du n-hexane, déshydrogénation du cyclohexane et en aromatisation du propane qu'un catalyseur préparer par échange cationique avec un sel de gallium. En fait, le véritable catalyseur est synthétisé lors du prétraitement sous hydrogène pendant lequel le suboxyde de gallium (Ga2O) issu de la réduction de Ga2O3 réagit avec les sites de Brønsted de la zéolithe pour donner des hydrures de gallium. La réaction de déshydrogénation des alcanes fait intervenir un site catalytique bifonctionnel composé d'un site de Lewis du Ga et d'un site basique généré par l'oxygène de la charpente zéolithique. L'activation du propane se produit sur un hydrure de gallium via un mécanisme de type alkyle. Les aluminosilicates dopés avec Ga sont plus performants que les gallosilicates, ce qui signifie que les espèces de gallium sont plus actives en extra-réseau que dans le réseau de la zéolithe.Le coke généré lors de l'aromatisation du propane est très polyaromatique avec plus de quinze noyaux benzéniques, localisé dans les micropores il s'avère très toxique. La création de mésopores intracristallins sans modifier les propriétés acides de la zéolithe (nombre et force des sites acides) est possible par un traitement alcalin. Leur présence permet de limiter les réactions de transfert d'hydrogène mais est peu efficace pour contrôler la croissance du coke, les mésopores sont mêmes négatifs pour la réaction de déshydrogénation rendant les catalyseurs bifonctionnels hiérarchisés inefficaces en aromatisation du propane ; l'étape cinétiquement limitante pour cette réaction étant la déshydrogénation
The mixing Ga2O3 with the H-ZSM-5 zeolite yields to the same catalytic performance in n-hexane cracking, cyclohexane dehydrogenation and propane aromatization than a bifunctional catalyst prepared by cationic exchange. The real catalyst appears upon hydrogen pretreatment in which gallium (Ga2O) suboxide that results from Ga2O3 reduction, reacts with the zeolite Brønsted sites to yield to gallium hydrides.The dehydrogenation reaction of alkanes involves a bifunctional catalytic site constituted of a Lewis site (Ga species) and basic site (an oxygen of the zeolite framework). The aluminosilicate catalysts loaded with Ga are more efficient than the gallosilicate catalysts, therefore extraframework gallium species is more active than the framework gallium species.The coke formed during the propane aromatization is very polyaromatic with more than fifteen benzenic rings, is very toxic. The creation of intracrystalline mesopores by alkaline treatment.preserves the acidic properties of the zeolite (number and strength of acidic sites). The mesopores allow limiting the hydrogen transfer reactions but is not very effective for impeding the growth of the coke, the presence of mesopores are even negative for the dehydrogenation reaction making inefficient the hierarchical bifunctional catalysts in propane aromatization; the kinetically limiting step for this reaction being dehydrogenation
