Ethylbenzene hydroisomerization over bifunctional zeolite based catalysts: The influence of framework and extraframework composition and zeolite structure

Transformation of ethylbenzene–m-xylene mixture on zeolites with different structures

“…The comparison of the products distribution shows that the intensity of the side reactions such as methyl and ethyl transfer are extremely high over both BEA samples in accordance with their large pore structure as other authors have observed [21,29]. The vigorous participation of the xylene reactant in these side reactions leads to very high, inadmissible loss of xylene products over both BEA materials.…”

Sorption behaviour of nanocrystalline MOR type zeolite for Th(IV) and Eu(III) removal from aqueous waste by batch treatment

“…The synthetic zeolites can of course be manufactured in a uniform phase-pure state. MOR is of great interest as it plays an important role in catalysis, sorption, electrochemistry [8,9] and also in other applications because of its ion exchange capacity which is related to its specific crystalline structure consisting of channels and cages. A sorbent to have good sorption potential, it should possess high surface area and for this it is desired to synthesize nanocrystallites [10].…”

Catalytic ring-attachment isomerization and dealkylation of diethylbenzenes over halide clusters of group 5 and group 6 transition metals

“…One of the main effects of platinum in bifunctional Pt/Al 2 O 3 -ZSM-5 catalyst in the transformation of ethylbenzene is to increase the rate of dealkylation [36]. A similar effect has been reported for Pt/Al 2 O 3 -zeolite catalysts in ethylbenzene hydroisomerization [37]. Rhenium is located in a neighboring position to the platinum group metals in the Periodic Table, and is similar to the platinum group metals in some of its properties.…”
