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 کاملFabrication and Characterization of Polyetherimide Hollow Fiber Membrane Contactor for Carbon Dioxide Stripping from Monoethanolamine Solution
In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...
متن کاملComplete Wetting of Gluons and Gluinos *
Complete wetting is a universal phenomenon associated with interfaces separating coexisting phases. For example, in the pure gluon theory , at T c an interface separating two distinct high-temperature de-confined phases splits into two confined-deconfined interfaces with a complete wetting layer of confined phase between them. In supersym-metric Yang-Mills theory, distinct confined phases may c...
متن کاملThe Role of Partial Internal Wetting in Hysteresis Behavior of Catalyst Pellet
The phenomenon of capillary condensation is studied through the weight change of condensed phase in an internally wetted porous pd catalyst pellet during the course of exothermic reacation of cyclohexane hydrogenation in a thermogravimetric analyzer (TGA). The direct measurement of condensed phase indicates that evaporation of condensed phase is confined to the macropores of catalyst pellet at ...
متن کاملTriple-point wetting of molecular hydrogen isotopes
Triple-point wetting is a well-known phenomenon of simple adsorbates on solid substrates, which involves, in the liquid phase above the triple-point temperature, T3, complete wetting with the formation of arbitrary thick films being observed, whereas below T3 only a few monolayers of the solid phase are adsorbed at saturated vapour pressure. This effect is usually ascribed to the substrate-indu...
