The ammoxidation of ethane over the conventional metal oxide and Co/zeolite catalysts faces challenge inadequate selectivity owing to formation CO2, N2, NOx. Here we report that Sn modified ZSM-5 catalyst is highly selective for ammoxidation. C- N-based acetonitrile selectivities are up 80 % 70 Sn/HZSM-5, but they below 60 20 %, Co/HZSM-5. We suggested (IV) cations critical active sites formati...

ZSM-11 zeolite was synthesized by hydrothermal treatment and cerium ion was incorporated by the ion exchange method.  The catalytic activity of cerium modified ZSM-11 zeolite was tested for the one-pot synthesis of 4H-pyran derivatives by cyclocondensation of aromatic aldehyde, malononitrile, and ethyl acetoacetate. The synthesized catalyst was characterized by Po...

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. ...

Ex-situ catalytic pyrolysis of pure glycerol to bio-aromatics over an un-modified H-ZSM-5 zeolite. • The conversion aromatics (BTX) with zeolite was investigated. An ex-situ approach used a separate and upgrading unit. A BTX peak carbon yield 28.1 ± 0.2% obtained. Catalyst performance for 5 reaction/regeneration cycles determined. Irreversible catalyst deactivation observed due dealumination th...
