Kinetics of Water Vapor Adsorption on Activated Carbon Langmuir2 Apr 1997 The adsorption of water vapor on a highly microporous carbon derived from the carbonization of coconut shell has been studied. This material was characterized by the adsorption of nitrogen at 77 K and carbon dioxide at 273 K. The micropore size distribution was determined using probe molecule vapors

The adsorption of water vapor by porous carbon ScienceDirectWater vapor adsorption isotherms on active carbon and graphite have been measured and analyzed by means of the two Dubinin-Serpinski equations and a third similar equation, based on the same principles. Surface oxide content and enthalpy of immersion measurements are shown to give support to the validity of these
Adsorption of water vapor and carbon dioxide at carboxylicCareful consideration should be given to the adsorption of water vapor and carbon dioxide on the surface of coal with regard to not only of how coal is handled, such as drying, transportation, but also to reactions related to gasification and liquefaction. Coal–water-mixtures (CWM) were examined in this study in related to the
Adsorption of Water Vapour on Solid Surfaces NatureIN their recent communication1, Dr. F. P. Bowden and Mr. W. R. Throssell reported conclusive quantitative evidence against the view at one time widely held that metal surfaces invariably adsorb water vapour strongly from air at high relative humidities. In my work of some years ago on the gravimetric determination of thin
Adsorption of water vapor by untanned hide and NIST PageAdsOJ'ption of water vapor by untanned hide and variou tannages oJ leather was determined at relative humidities ranging from 0 to 96 percent at 100° F. The Brunauer,. Emmett, and Teller equations for adsorption of gases in multimolecular layers were applied to the data. Adsorp1ion for all of the samples below a relative
Influence of temperature on the adsorption of water vapor byThe adsorption of water vapor by collagen, commercial hide powder, and several leathers was determined at various relative humidities ranging from about 0 to 96 percent, at 28°,. 50°, and 70° C. Determinations were also made on chestnut and quebracho tannins at. 28° C at various relative humidities. The results indicate

Isotherm Equation for Water Vapor Adsorption Semantic ScholarA simple isotherm model has been developed for the type-5 equilibrium adsorption systems by considering the effects of both primary and secondary adsorptive sites. The model was applied to interpret experimental data describing water vapor adsorption capacities of four activated carbon adsorbents for relative.
Water Vapor Adsorption and Soil Wetting InTechOpenConsequently, measurements and detailed information about soil water sorption, water content, behavior, and potential are required. In that concern, water vapor adsorption is an important phenomenon in arid and semi-arid regions, as well as in dry periods of tropical soils. Therefore, quantifying adsorption is important for

Adsorption of Water Vapor by Bare Soil in an Olive Grove inData for water vapor adsorption and evaporation are presented for a bare soil (sandy loam, clay content 15%) in a southern Spanish olive grove. Water losses and gains were measured using eight high-precision minilysimeters, placed around an olive tree, which had been irrigated until the soil reached field capacity
Measurement and Modeling of Water Vapor Adsorption on ZeoliteThe adsorption of water vapor on Zeolite 4A has been analyzed. Both equilibrium and kinetics are examined. The equilibrium is measured with a static-volumetric method in a wide range of partial pressure and temperature and is modeled by several conventional approaches and a new type isotherm model, which fitted the
