The realization of biofuels and chemicals requires the development highly active selective catalysts, which are resistant to deactivation. A conventional ZSM-5 (SiO2/Al2O3 = 30) was modified with 0.2 M NaOH generate a mesoporous zeolite support. parent zeolite, mic-ZSM-5, hie-ZSM-5, silica support, SiO2, were impregnated 5% nickel characterized using X-ray powder diffraction (XRD), Brunauer–Emm...

Medium-pore (diameter ~ 6A) zeolites such as ZSM-5 and silicalite impregnated with Group VIII metals provide selective catalytic pathways for the conversion of synthesis gas to gasoline or olefins. Mössbauer and magnetic studies on these catalysts containing iron or iron plus cobalt are reported. The zeolites were impregnated with metal nitrate solutions, reduced, and carbided to yield showed F...

Catalytic pyrolysis behavior of synthesized microporous catalysts (conventional Zeolite Socony Mobil–5 (C-ZSM-5), highly uniform nanocrystalline ZSM-5 (HUN-ZSM-5) and β-zeolite), Mesoporous catalysts (highly hydrothermally stable Al-MCM-41 with accessible void defects (Al-MCM-41(hhs)), Kanemite-derived folded silica (KFS-16B) and well-ordered Al-SBA-15 (Al-SBA-15(wo)) were studied with waste po...

Zeolite ZSM-5 presents a great source of interest in catalysis because of its shape selective properties. The absence of a relationship between the template size and shape of the structure generated during the synthesis of zeolites is illustrated by the case of ZSM-5. In this study, we have investigated the role of ethanol, methyltriphenylphosphonium bromide (MTPBr) and cetyltrimethylammonium b...

The use of H-ZSM-5 with various binders (Al 2 O 3 , SiO and kaolinite, 10 wt% on catalyst formulation) for the catalytic conversion glycerol to bio-based aromatics (GTA) was investigated in a continuous bench-scale unit at pyrolysis temperature 450 °C, upgrading 500 WHSV pure 1 h ?1 atmospheric pressure, their performance compared (SiO /Al molar ratio 28). latter gave peak BTX carbon yield ca. ...
