The hydrocarbon-type content of petroleum fractions has traditionally been determined by using different techniques but often with poor agreement among the various results for a given sample. In this study, three different fractions were analyzed by

The 29Si MAS n.m.r. spectra of highly dealuminated zeolites are shown to exhibit separate Si(OAl) resonances due to crystallographically inequivalent lattice sites. The chemical shift dispersion due to crystallographic inequivalence is of the same or

The study of 29Si MAS NMR spectra of zeolites of both low and high Si/Al ratios has provided insight on the factors affecting the residual 29Si line-widths of these materials. It is found that the ...

The 29Si MAS NMR spectra of dealuminated zeolites have been studied, where the chemical shift dispersion due to structurally distinct SiO4, tetrahedra is comparable (or greater) in magnitude to first coordination sphere effects. The results 29Si sugg

The application of solid state NMR techniques to the study of zeolite catalysts has contributed, greatly to our understanding of zeolite structures. The background to the experimental techniques needed to obtain high resolution 29Si and 27Al spectra
