adsorbent

However , in the view of the results of research in application of adsorption refrigeration , the solid adsorption refrigeration technique remains undeveloped , and because of low refrigeration efficiency , the high cost and the low heat utilization ratio and together with some other disadvantages , the adsorption refrigeration has not reached the level of industrialization yet so the author chose the urgent and critical problem in the application technique of adsorption refrigeration as the research target for the - developing the well - performing adsorbent - adsorbate working pairs 然而,從吸附制冷實用化研究成果來看,固體吸附制冷技術還不夠成熟,存在著單位吸附劑的制冷功率低,系統造價高,熱利用率低等問題,尚未達到工業化水平。為此,本文選擇目前在吸附制冷技術應用開發中亟待進一步解決的關鍵技術? “開發性能優良的吸附制冷工質對”作為研究目標。

3 . the mathematical model for heat and mass transfer in the adsorbent bed is established , the porous of adsorbent , the flow of adsorbate in adsorbent , the characteristic of non - equilibrium adsorption are combined in the model , and a more accurate model of fluid flow in porous media - ergun model is adopted 它綜合考慮了吸附劑的多孔介質結構,吸附質氣體在吸附劑內的流動,吸附的非平衡特性等,并且在吸附質氣體流動模型的選擇上,采用了ergun多孔介質流動模型,比常規的數學模型更全面準確地描述了吸附床傳熱傳質的動態特性。

A method to calculate quantitatively the adsorption volume or adsorption space of per mass of adsorbent derived from both the adsorbed molecule volume and the maximum adsorbance of a solute in an adsorption isotherm under a given experimential condition is presented firstly for a solid / liquid adsorption system of the solute in a dilute aqueous solution . this method is suitable for not only mono - layer adsorption , but also mani - layer adsorption and micelle adsorpion of surfactant constructed by hydrophile and lipophile groups . therefore , the surface concentration of the adsorbate , cs , deduced from the adsorption volume is possessed of the meaning of true concentration , and the value of the patition coefficient of the adsorbate between solid and liquid phass , p , attained by the cs and the c , solution concentration of the adsorbate , can be accurate . the foregoing a set of calculations are presented for the solid - liquid adsorption systems consisted of the wool fiber and separately dodecyltrimethyl - ammonium bromide ( dtab ) and hexadecyltrimethyl - ammonium bromide ( ctab ) in this paper . this provides a strong basis for adsorption thermodynamic investigation of adsorbate 對稀溶液中溶質的固/液吸附體系,首次提出了根據吸附分子體積和實驗條件下吸附等溫線中的最大吸附量計算單位質量吸附劑的吸附體積或吸附空間的方法.此法適用于單層吸附,也適用于多層吸附和具有親水親油結構的表面活性劑分子的膠團吸附.由此,吸附質的表面相濃度cs具有真實濃度的含義,相應地,計算得到的溶質的固/液分配系數p就有了準確值.分別計算由溴代十二烷基三甲銨( dtab )和溴代十六烷基三甲銨( ctab )與羊毛纖維構成的液/固體系分配系數等,為溶質吸附的熱力學研究奠定了基礎

The dissertation shows how a series of well - performing composite adsorbents that prepared by author suitable for the features of adsorption refrigeration are gained by using water and ethanol as cryogen ( adsorbate ) , which cause no harm to body and environment . the performance of the working pairs of water or ethanol with the composite adsorbents in the refrigeration through adsorption and desiccant cooling are thoroughly examined by experiments . the dissertation also examines , through energy analysis , the refrigeration efficiency and utilization ratio of the adsorption refrigeration , and analyzes the economic potential of the adsorption air - conditioning 以對人體無傷害、對環境無污染的水和乙醇作為吸附制冷工質,研制出適合于吸附制冷特點的性能優良的一系列復合吸附劑;對水或乙醇與自制復合吸附劑組成的制冷工質對的吸附式制冷和吸附除濕制冷的性能進行了深入的實驗研究;用有效能分析方法討論了吸附制冷循環的制冷效率和能量的利用率;對吸附式空調的經濟性進行了分析。

We infered that this new absorption band was associated with the effect of charge - transfer transition between adsorbates and colloidal silver particles , not the effect of the surface plasma resonance due to the silver particles aggregation which was usually attributed to in previous research work 我們將其歸因于與納米銀顆粒表面間的電荷轉移效應( ct ) ,而非通常所認為的因銀膠凝聚而產生的表面等離子體共振吸收效應。

The former is to gain refrigeration volume through the process of adsorbing adsorbate ( cryogen ) by adsorbents ; while in desiccant cooling , solid adsorbent is used to remove the moisture from the surrounding 吸附式制冷是利用固體吸附劑對吸附質(制冷劑)的吸附過程而獲得冷量的。吸附除濕制冷是用固體吸附劑將空氣中的水蒸汽部分除去,并與蒸發冷卻等技術結合,達到制冷效果的制冷方法。

In a paper published jan . 18 in science express , the scientists describe how they got an adsorbate molecule ( anthraquinone ) to pick up two carbon dioxide atoms and carry them in a specific direction on a flat copper surface 1月18日的“科學快訊”上的一篇文章中的研究者描述了他們將攜帶有二氧化物原子的一種吸附分子(蒽醌)定向進入扁的銅表面。
