Simultaneous observation of alkenyl carbenium ions and alkoxy species on HZSM-5 zeolite by adsorption of 1-methylcyclopentene and 1-methylcyclopentanol

Article Abstract:

The observation of simultaneous formation of alkenyl carbenium ions as well as alkoxy species by adsorption of 1-methylcyclopentene and 1-mentylcyclopentanol on HZSM-5 at 196 K and above is reported. Further, an investigation on the adsorption behavior of various cyclic precursors adsorbed on zeolites using in-situ infrared (IR) spectroscopy, a powerful technique that is widely used for studying zeolites is presented.

Detailed process of adsorption of alkanes and alkenes on zeolites

Article Abstract:

The adsorption of alkanes and alkenes on zeolites is investigated in a study by comparing the adsorption characteristics for three types of zeolite. The structure and process of experimentally observable adsorption is found to differ depending on the type of zeolite and adsorbing molecule, and the elementary adsorption process could be interpreted based on this differing behavior.

Ultra-fine tuning of microporous opening size of zeolite by CVD

Article Abstract:

Transmission electrons microscopy (TEM) studied the porous structure of a chemical vapor deposition (CVD) layer on a silicalite zeolite. The adsorption results show that when the amount of CVD silica increases the size of the opening mouth is decreased.
