Stability of Zeolites in Hot Liquid Water | The Journal
Zeolites Y and ZSM-5 with varying Si/Al ratios are treated in liquid water at 150 and 200 °C under autogenic pressure to assess their hydrothermal stability. The changes in the structure are characterized by atomic absorption spectroscopy, X-ray diffraction, scanning electron microscopy, argon physisorption, 27Al and 29Si MAS NMR spectroscopy, temperature-programmed desorption of ammonia, and

The Effect of Water on the Adsorption of CO2 and C3H8
The effect of small amounts of water, in regard to inhibiting the adsorption of carbon dioxide (CO2), on several different cationic forms of zeolite X has been investigated using the zero length column (ZLC) technique, coupled with temperature-programmed desorption (TPD) measurements. This is shown to be a very effective way to study the effect of a strongly adsorbed species (water) on the

The effect of water increases the diffusion coefficients of F and Cl by Mafic rocks, dominantly hornblende-gabbros, pyroxene-gabbros, olivine- no more than a factor of 3 compared to the anhydrous melt (DCl= 3.010-11 - pyroxene gabbros, occur as separate bodies, or more commonly, associated with 1.910-10 m2s-1; DF = 4.010-11 - 1.610-10 m2s-1).
US4393082A - Ion exchange materials to increase
In the feeding of non-protein nitrogen (NPN) compounds such as urea to ruminants, the NPN compound is decomposed to ammonia in the rumen. To mitigate against toxic effects of the resulting high ammonium ion content of the ruminal fluid, a zeolite, or crystalline alumino silicate cation exchange material, is introduced into the rumen and maintained therein so that ammonium ions formed by NPN
