In this investigation, the ZnO/g-Al2O3 Nanocomposite synthesized and characterized for removal and sorption of hydrogen sulphide. Firstly, gamma alumina support was synthesized using precipitation method with ammonium carbonate and then, zinc oxide was impregnated on support. The nanocomposite were extensively characterized before and after sorption process in order to determine the structural effects with XRD, BET, FT-IR, FE-SEM and EDS analysis. The BET result was shown that the 320 square meters specific area per grams of absorber. Also, FE-SEM images showed that the mean size of powders was about 7 nm. Gas flow of 200 ppm hydrogen sulphide in equilibrium with nitrogen inter to adsorption column and sorption process was done. At optimum condition of adsorption operational parameters, the adsorption capacity was 150.43 mg per gram of absorber. The variation of composite morphology and also XRD phases at before and after sorption showed that this sorption is chemically sorption. Also, the XRD phases in gamma alumina showed that the hydrogen sulphide removal was physically sorption. |
