Two dimensional mapping of H spin densities in test objects were obtained using a projection reconstruction method. The experiments were carried out on a modified commercial spectrometer. The spatial distorsions of the system are discussed and illust

The measurement of self-diffusion coefficients D by the NMR spin echo pulsed-field gradient G technique can be corrupted for systems having a background magnetic field gradient G(o). The corrupting cross-term G(o)G can be eliminated by the use of alt

In order to understand the role of different aluminum species in the selective catalytic reduction of nitrogen oxides with methane over H-mordenites, solids with varying Si/Al ratios (5.9-16.9) were prepared by acid leaching. They were thoroughly cha

H-mordenites are active for the SCR reaction but they suffer irreversible partial deactivation after being on stream for one hour at 650 degrees C. The reaction orders and activation energies are not significantly affected by deactivation. This indic

Three-dimensional chemical shift imaging has been used to map oil and water in porous rock samples. This method does not rely on differences on relaxation times T1 or T2 and works quite well, provided the components of the fluids give reasonably well

Studies of the selective catalytic reduction (SCR) of nitrogen oxide with methane over H-mordenites were made to develop a basic understanding of the role of acid sites in this reaction and the mechanism of deactivation of these solids. A series of H
