Nanoslabs with MFI zeolite framework topology and having aluminosilicate composition were assembled into nanosize crystals and Zeogrid materials. The nanosize MFI zeolite had a particle size of ca. 200nm. Micron sized Zeogrid spheres were assembled by precipitating a nanoslab suspension through cetyltrimethylammonium bromide (CTAB) addition and calcination of the precipitate. Zeogrid is a layered...
A quaternary mixture of hexane, heptane, octane, and nonane was hydroconverted on Pt/H–Y with a Si/Al ratio of 2.7 and two Pt/USY catalysts with Si/Al ratios of 13 and 30, respectively. Although these zeolite catalysts have largely different activities, they show unique yield curves of monobranched isomers, multibranched isomers, and cracked products versus conversion. Intrinsic reaction rate constants...
