Differences between ZSM-5 and ZSM-11 zeolite catalysts in 1-hexene aromatization and isomerization

Fuel Processing Technology, 2010
ZSM-5 and ZSM-11 zeolites with high crystallinity are synthesized and tested in the aromatization and isomerization reactions of 1-hexene at 370 degrees C in a continuous flow fixed bed. The results indicate that ZSM-5 and ZSM-11 zeolites possess similar

Trimetallic Cu–Ni–Zn/H-ZSM-5 Catalyst for the One-Pot Conversion of Levulinic Acid to High-Yield 1,4-Pentanediol under Mild Conditions in an Aqueous Medium

, 2021
The one-pot direct conversion of levulinic acid (LA) to 1,4-pentanediol (1,4-PDO) was investigated over a trimetallic Zn-promoted Cu–Ni alloy on a H-ZSM-5 (Cu–Ni–Zn/H-ZSM-5) catalyst.

Low-Temperature Methane Combustion over Pd/H-ZSM-5: Active Pd Sites with Specific Electronic Properties Modulated by Acidic Sites of H-ZSM-5

ACS Catalysis, 2016
Pd/H-ZSM-5 catalysts could completely catalyze CH4 to CO2 at as low as 320 °C, while there is no detectable catalytic activity for pure H-ZSM-5 at 320 °C and only a conversion of 40% could be obtained at 500 °C over pure H-ZSM-5. Both the theoretical and

Novel preparation of binder-free Y/ZSM-5 zeolite composites for VOCs adsorption

, 2021
Hydrophobic zeolites have been considered as effective adsorbents for capturing volatile organic compounds (VOCs). In this contribution, a series of binder-free Y/ZSM-5 zeolite composites were prepared through crystallization of shaped precursors by a ...

A review on the catalytic pyrolysis of biomass for the bio-oil production with ZSM-5: Focus on structure

, 2020
A higher amount of oxygenated compounds in bio-oil obstructs its use in the existing petroleum-based infrastructures. In order to convert oxygenates into hydrocarbons and less reactive compounds, a number of catalysts have been studied in the catalytic ...

Nitromethane decomposition over Cu-ZSM-5 and Co-ZSM-5

Physical Chemistry Chemical Physics, 2001
To better understand the nitromethane decomposition mechanism over Cu-ZSM-5 and Co-ZSM-5, CH3NO2 and CO adsorption on Cu-ZSM-5 and Co-ZSM-5 was studied by IR and EPR spectroscopies. After adsorption of nitromethane on H-ZSM-5, Al(III)–NCO forms at 200°C.
