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

The investigations on the synthesis of zeolite ZSM‐5 (I)
Crystal Research and Technology, 1989AbstractThe effect of the composition of reacting mixtures on the crystallinity of zeolite ZSM‐5 was investigated. The mixture of ethanol and ammonia was used as a templating agent. The quantitative determination of the phase composition of the obtained preparations was made on the ground of X‐ray diffraction.

Materials Chemistry and Physics, 1993
Abstract The kinetics of the crystallization of the (NH4-TPA)-ZSM-5 zeolite in two different systems have been determined as a function of the molar ratio of SiO 2 Al 2 O 3 and the nature of the silica source. The influence of organic template molecules and the reactivity of silica sources on the rate of crystallization as well

Adsorption of water on ZSM-5 zeolites
Thermochimica Acta, 1995The non-isothermal desorption of water adsorbed on ZSM-5 zeolites at room temperature shows, depending on the cation type (H+, Na+), differently structured desorption curves. A kinetic analysis based on various methods shows that the course of desorption is well described by a first order rate equation considering a distribution function for the ...

Adsorption of Methanol on ZSM-5 Zeolites
Langmuir, 1997The interaction of methanol with a NaZSM-5 and a HZSM-5 zeolite was investigated by means of temperature-programmed desorption (TPD) and adsorption measurements. For both zeolites the desorption curves are structured, indicating different adsorption sites.

Crystallization kinetics of zeolite ZSM-5
Zeolites, 1992Abstract Zeolite ZSM-5 was synthesized from aluminosilicate gels in the presence of organic templates — tetrapropylammonium bromide (TPABr) and pyrrolidine (Py) — at temperatures of 423, 438 and 453 K. Nucleation and crystallization processes were subjected to a detailed kinetic analysis.

Diffusion of cyclohexanes in ZSM-5 zeolites
Journal of Catalysis, 1988Abstract Diffusion coefficients have been measured for the diffusion of cyclohexane and alkylcyclohexanes ranging from methyl- to pentylcyclohexane in ZSM-5-type zeolites using the samples of flat plate-like crystallite. The uptake curves of Cyclohexanes by these samples are considered to represent primarily the diffusion of Cyclohexanes into the ...
