Characteristic of MOR-framework zeolites synthesized in fluoride-containing media and related ordered distribution of Al atoms in the framework

Article Abstract:

The MOR type zeolites with Si/Al ratios of 5.19-9.00 were synthesized in the presence of fluoride ion (denoted by MS-F). The solid-state (super 29)Si MAS NMR measurements revealed that the number of Si atoms with a Si(2Al) environment in MS-F is less than that in MS-C of the same Si/Al ratio.

Physisorption and chemisorption of some n-hydrocarbons at the bronsted acid site in zeolites 12-membered ring main channels: ab initio study of the gmelinite structure

Article Abstract:

The physisorption and chemisorption of some n-hydrocarbons are studied. It is shown that the relative stability of protonated hydrocarbons depends on the length of the molecule.
