“…CO 2 adsorption on A [8,9], X [10], Y [11], mordenites [12], ZSM-20 [13], chabazites [14], and mesoporous molecular sieves [15] has been studied extensively to determine the effect of ion type on the adsorption equilibrium and energetics. However, in these papers, the degree of exchange was not studied as a pertinent parameter.…”

“…On the other hand, CO oxidization performance declines at the higher initial concentration of O 2 . Since H 2 O that is a byproduct in this reaction is adsorbed by mesoporous silica more easily than CO, O 2 and CO 2 [24], the CO adsorption by mesoporous silica might be dropped under the higher initial concentration of O 2 . Therefore, the CO oxidization performance of mesoporous silica loaded with TiO 2 also declines.…”

Hydrogen (H2) is normally used as the fuel to power polymer electrolyte fuel cell (PEFC). However, the power generation performance of PEFC is harmed by the carbon monoxide (CO) in the H2that is often produced frommethane (CH4). The purpose of this study is to investigate the experimental conditions in order to improve the CO oxidization performance of mesoporous silica loaded with TiO2. The impact of loading ratio of TiO2and initial concentration ratio of O2to CO on CO oxidization performance is investigated. As a result, the optimum loading ratio of TiO2and initial concentration ratio of O2to CO were 20 wt% and 4 vol%, respectively, under the experimental conditions. Under this optimumexperimental condition, the CO in rich H2in the reactor can be completely eliminated from initial 12000 ppmV after UV light illumination of 72 hours.

“…Many water vapour adsorbents have been developed for gas drying and purication, heat of adsorption transformer, such as silica gel, 2 zeolite 3,4 and activated carbon. 5 A plenty of innovative materials are under consideration, including aluminophosphate, 6 metalloalu-minophosphate, ordered mesoporous silica 7,8 and aerogel. At present, they have not been widely applied in water vapor adsorption by limited low water uptake or adsorption rate.…”

Inorganic composite adsorbent CaCl₂/MWNT for water vapor adsorption

CaCl 2 has been proposed as an advanced chemical adsorbent for cheap, non-toxic and powerful in water vapour adsorption. One of the key barriers for practical application is poor in mass and heat transfer due to large volume expansion, serious agglomeration and low thermal conductivity. A novel CaCl 2 /MWNT adsorbent is prepared with carbon nanotube as matrix. In the composite, a part of CaCl 2 nanoparticles are adsorbed on the matrix surface, and the else hygroscopic salts are filled in the space of matrices. The nanoparticles with big specific surface areas can be fully contacted with water vapour, enhancing water uptake and adsorption rate. Furthermore, the paper has reported that hydrophilic/hydrophobic property of the MWNT is relation with the adsorption performances of the CaCl 2 /MWNT composite. It is found that hydrophilic matrix can enhance water-retaining property, and keep a stable porous structure of the material. Finally, a simple modified method adding PVP as a water-based adhesive into the CaCl 2 /MWNT composite adsorbent is also reported for the first time. The PVP powder improves water-retaining property of the CaCl 2 /MWNT adsorbent during adsorption process. For regeneration process, the PVP water-based adhesive makes adsorbent particles agglomerate macroscopically under unchanged their microcosmic structure. At low humidity condition, adsorption rate of CaCl 2 /MWNT composite is obviously enhanced by the PVP powder. Consequently, the modified CaCl 2 /MWNT composite with the hydrophilic matrix will promise for commercial application in water vapour extraction, thermal storage energy and other applications.
