Adsorbent CuO/γ-Al 2 O 3 was successfully prepared by the dry impregnation using Cu(NO 3 ) 2 .3H 2 O solution on commercial γ-Al 2 O 3 . Impregnation and calcination process was be done repeatedly to get a desired CuO content on the support. The impregnations were done at 50 o C for 8 hours or 120°C for 5 hours. Calcinations were carried out at a temperature of 400 o C for 8 hours. Adsorbent obtained from this preparation contained Cu: 7.93% (named 8Cu), 14.76% (15Cu) and 28.98% (30Cu). Pore characteristic indicated that the surface area decreased with the increase in Cu content in the adsorbent (from 207 in original support to 124 m 2 /g in 8Cu). Similar tendency was found for the pore volume (from 0.47 to 0.28 mL/g).In batch adsorption test, the amount of adsorbed SO 2 was calculated from the increase in mass of adsorbent. Adsorbent 8Cu had the best adsorption capacity in term of mol ratio, ie. 0.78 SO 2 /CuO (close to stoichiometry). Original support of γ-Al 2 O 3 was found to be inert to SO 2 . In semi-continue test, the adsorption was carried under a flow of gas containing 2.5% SO 2 . The amount of adsorbed SO 2 was calculated from the different of SO 2 content between influent to effluent. It was found again that the best adsorbent was 8Cu with the adsorption capacity of 0.97 mol/mol CuO.

“…al, 2002). Moreover, adsorption of SO 2 by CuO takes place at a temperature in the range of flue gas temperature, 300-450 o C (Mathieu, et al, 2013;Xie et al, 2003). The use of γ-Al 2 O 3 as support for CuO offers advantages a large specific surface area (150-300 m 2 / g), and heat resistance of up to 700-900 o C.…”

“…An industrial sector with a major environmental impact is the energy sector, which is a major source of pollution by combustion of fossil fuels [1][2][3]. Desulfurization of combustion gases is currently the subject of numerous experimental research and research projects that have proposed and developed numerous desulfurization processes: dry, semi-dry and wet [4][5][6][7][8].…”

ABSTRACT. This paper presents the experimental results obtained by sulfur dioxide chemisorption into carbonate suspension with sulfites addition at different temperatures and concentration of the absorbent suspension. Presence of sulfites in the absorbent suspension has a positive influence on the global rate of the absorption process. The acceleration of SO2 chemisorption process in the absorbent suspension containing MeSO3 -MeCO3 is determined by the higher concentration of ions in the liquid phase resulted from higher solubility of MeSO3 comparative with MeCO3. The addition of MeSO3 at a concentration of 10% in the composition of the absorbent suspension determines a significant decrease of the time required for obtaining a high conversion.

“…They have attracted much attention in various areas since their discovery [1,2]. Due to their unique properties, notably large surface area and pore size, tunable pore size, chemical functionalization of pore wall, and high thermal stability [3][4][5], mesoporous silica materials have attracted great attention in many elds such as catalysis [6], environmental puri cation [7][8][9], air pollution [10][11][12][13], and desulfurization [14]. It has been noted that the principal feature of the mesoporous silica materials, namely, their periodic and ordered mesoporous structure, does not o er speci c advantages in some special applications, as it occurs in catalysis, e.g.…”

H2S Removal Using ZnO/SBA-3: New Synthesis Route and Optimization of Process Parameters

Abstract. H 2 S is a major toxic compound that could be found in air, water, and fossil fuels and causes some bad e ects such as acidic rain and corrosion. In the present work, SBA-3 (Santa Barbara University no. 3) with three di erent weight percentages of ZnO, namely, 5%, 10%, and 15%, was synthesized via an in situ approach. All synthesized samples were characterized using atomic absorption spectrometry, X-Ray Di raction (XRD), nitrogen adsorption, and Transmission Electron Microscopy (TEM). The obtained results from XRD and nitrogen adsorption con rmed that all the samples almost retained their ordered structure after incorporation of ZnO nanoparticles within the mesopores of SBA-3. TEM images showed that ZnO nanoparticles were arranged along the direction of mesopores of SBA-3. Then, adsorption of H2S from a model gas was investigated. A three-factor Box-Behnken design with ve center points and one response was performed for the evaluation of e ect of three process parameters, namely, ZnO wt%, space velocity, and temperature, on the adsorption of H 2 S and a quadratic model (r 2 : 0.9185) was developed to navigate the design space. Temperature had the largest and space velocity had the lowest e ect on the breakthrough of H 2 S. The optimum breakthrough time (t bp ) was 588 min.
