ZSM-5 Zeolite Membrane

2014
ZSM-5 (Zeolite Socony Mobil-5, patented by Mobil oil company in 1975) is a high silica zeolite with a MFI framework structure (Mobil Five) characterized by the formula |(Na x(H 2O) 16|[Al xSi 96−xO 192], where x

Catalytic pyrolysis of pinewood over ZSM-5 and CaO for aromatic hydrocarbon: Analytical Py-GC/MS study

, 2020
A higher amount of oxygenates is the main constraint for higher yield and quality of aromatics in catalytic pyrolysis while a study of hydrocarbon production with a balance of reactive species lies importance in the catalytic upgrading of pyrolytic vapor.

Adsorption of hydrocarbons and water on ZSM 5 and on ZSM 5 converted by dealumination into silicalite

Journal of Inclusion Phenomena, 1987
Adsorption measurements of hydrocarbons and water have been performed on ZSM 5 (Si/Al=30) and on two samples prepared from this by dealumination. The properties of the highly dealuminated sample agree essentially with those of silicalite obtained by direct synthesis.

Effect of ZSM-5 waste dosage on the properties of autoclaved aerated concrete

, 2021
ZSM-5 (Zeolite Socony Mobil-5) waste, the spent product of ZSM-5, was directly dumped into ponds in the past which causes both environmental degradation and resource loss.

Adsorption and Desorption Behavior of NO on H-ZSM-5, Na-ZSM-5, and Na-A as Studied by EPR

Journal of Magnetic Resonance, 2002
Nitric monoxide probe molecules are used to characterize the Lewis acid properties of sodium cations and aluminum defect centers in various zeolite materials. The adsorption-desorption behavior of NO probe molecules is studied at different temperatures for Na-A, Na-ZSM-5, H-ZSM-5, and silicalite.

Hollow ZSM-5 zeolite encapsulated Ag nanoparticles for SO2-resistant selective catalytic oxidation of ammonia to nitrogen

Separation and Purification Technology, 2019
Hollow ZSM-5 encapsulating Ag particles (Ag/ZSM-5-OH) have been successfully synthesized, characterized and tested in NH3-SCO reaction. In comparison with Ag/Al2O3 and Ag/ZSM-5-OH, Ag/ZSM-5 catalyst displayed the lowest T100 (110 °C), much higher TOF and

Ozone-Assisted Catalysis of Toluene with Layered ZSM-5 and Ag/ZSM-5 Zeolites

Plasma Chemistry and Plasma Processing, 2013
This paper presents a new type of ozone-assisted catalysis for toluene decomposition. The different catalytic activities of ZSM-5 and Ag/ZSM-5 were incorporated into a layered catalyst with a tandem configuration. Instead of increasing the amount of metal catalyst, the layered catalyst was formed, which had an equal amount of bare ZSM-5 and Ag/ZSM-5 ...

Aromatics production with metal oxides and ZSM-5 as catalysts in catalytic pyrolysis of wood sawdust

Fuel processing technology, 2019
Dual catalysts are proposed in this study to convert biomass pyrolysis vapors into aromatics. Metal oxides (CaO, Al2O3, and ZnO) and ZSM-5 were introduced into the catalytic upgrading process.

Nitrosylic complexes in Ag(I)–ZSM-5: a comparison with Cu(I)–ZSM-5

Microporous and Mesoporous Materials, 1999
Abstract Starting from (NH4)+–ZSM-5, we have prepared Ag(I)–ZSM-5 and Cu(I)–ZSM-5. In both cases a nearly total cation exchange has been achieved. The local environment of Ag(I) and Cu(I) cations, as determined by an EXAFS study, is very similar in both cases: Cu(I) is surrounded by 2.5±0.3 oxygen atoms at 2.00±0.02 A and Ag(I) is surrounded by 2.5±0.
