Partial wetting in porous catalysts: wettability and wetting e&ciency
Qualitative changes in the local (pore level) wetting e&ciency of a porous catalyst as a function of catalyst wettability are proposed based on monitoring the 1-D motion of the solid-liquid-gas contact line. As catalyst wettability is increased, the resulting wetting e&ciency is likely to show two distinct transitions viz., (1) a sudden decrease that is inspired by coalescence of neighboring ri...
متن کاملExperimental Study of Wettability Alteration to Preferential Gas-Wetting in Porous Media and Its Effects
In a recent theoretical study, Li and Firoozabadi showed that if the wettability of porous media can be altered from preferential liquid-wetting to preferential gas-wetting, then gas well deliverability in gas condensate reservoirs can be increased. In this paper, we present the results that the wettability of porous media may indeed be altered from preferential liquid-wetting to preferential g...
متن کاملMolecular dynamics of wetting layer formation and forced water invasion in angular nanopores with mixed wettability.
The depletion of conventional hydrocarbon reservoirs has prompted the oil and gas industry to search for unconventional resources such as shale gas/oil reservoirs. In shale rocks, considerable amounts of hydrocarbon reside in nanoscale pore spaces. As a result, understanding the multiphase flow of wetting and non-wetting phases in nanopores is important to improve oil and gas recovery from thes...
متن کاملThe Effect of Disinfectants and a Surface Wetting Agent on the Wettability of Elastomeric Impression Materials: An In Vitro Study
BACKGROUND This study was carried out to evaluate the effect of two commercially available chemical disinfectants namely sodium hypochlorite and glutaraldehyde and a surface wetting agent on the wettability of three high precision elastomeric impression materials, addition silicone, condensation silicone and polyether. MATERIALS AND METHODS Three different types of elastomeric impression mate...

microfabrication applications, it is widely used to transfer the designed patterns from an etching mask to the substrate. When the sample is immersed into the etching bath, the etchant only contacts and reacts with the substrate surfaces where are uncovered by the etching mask. The suitable materials for the mask can be polymers or other materials such as photoresist, SU-8,SiO2 andSi3N4, which ...
