    Adsorption performance of hydrophobically modified silica

    In other words, an ordinary silica gel (SG-1) was chosen as the raw material and hydrophobically modified with a composite modifier which contains TMCS especially under microwave exposure, and then the adsorption performance of the modified silica gel to VOCs from the polluted air with high water content was evaluated.

    (PDF) Performance Test of a Silica Gel Dehumidifier

    This article reports the performance test of a silica gel dehumidifier intended to use inside air conditioned spaces. The air velocity was varied at 0.2, 0.4, and 0.6 m/s (corresponding to the air

    Evaluation on performance of solar adsorption cooling

    They concluded that the silica gel was a recommended adsorbent over AQSOA-Z02 in term of higher SCP. The SCP of the silica gel system was as high as 460 W/kg. As the silica gel–water adsorption chiller was integrated with a wet cooling tower, the performance of the adsorption system was able to be improved .

    A CFD Simulation on How the Different Sizes of Silica Gel

    6.3. The Performance of the Silica Gel. The performance of the silica gel systems is commonly illustrated and evaluated on the basis of adsorption of the water vapour molecules in the adsorber bed over time. These simulations reveal the impact of silica gel granule adsorption rates: 1 ? = ? ⋅ ? ? ? ?.

    Interfacial properties of mercaptopropyl-functionalised

    The interfacial properties of the mercaptopropyl-functionalised silica gel (MP–SG) and its performance for the adsorption of gold(I) from a thiosulfate solution were examined. An optimized modification procedure was determined to produce a MP–SG mercapto group content of 1.1 mmol·g −1. Characterisation of the prepared samples revealed

    PHYSICAL AND OPERATING CONDITIONS EFFECTS ON SILICA GEL

    – Silica gel/water adsorption cycle can be powered using low grade heat sources (55-100°C). – Silica gel/water pair has relatively high equilibrium Ads/Des rate. – Water has high latent heat of evaporation. – Water is thermally stable within wide range of operating temperatures. – Water is combatable with wide range of materials

    Adsorption Equilibrium of Water on Silica Gel | Journal

    A new test rig for measuring the adsorption equilibrium of water on silica gel has been developed. The adsorption equilibrium of water on silica gel was then measured using the weight method. The measured temperature ranged from (25 to 90) °C, and the absolute pressure was in the range of (300 to 20 000) Pa. The water uptake of silica gel varied from (0.03 to 0.30) kg·kg−1. Data obtained

    History. Silica gel was in existence as early as the 1640s as a scientific curiosity. It was used in World War I for the adsorption of vapors and gases in gas mask canisters. The synthetic route for producing silica gel was patented by chemistry professor Walter A. Patrick at Johns Hopkins University in 1918.. In World War II, silica gel was indispensable in the war effort for keeping

    What types of desiccants do you use and what are their

    SK-600 silica gel is a clear beaded desiccant with a diameter of 2.36 to 4.75 mm. It has a high surface-area-to-weight ratio and adsorbs more moisture than any other type of desiccant. Silica gel fractures when exposed to mist, and its adsorption performance degrades when regenerated at high temperatures.
