Preparation of Some Bifunctional Catalysts for Direct Conversion of Synthesis Gas to Dimethyl Ether


Department of Chemical Engineering,Amirkabir University of Technology


present study, twenty three catalysts for dimethylether (DME)synthesis were prepared, according to a pre-designed research program consisting of four phases. In each phase, by applying the Taguchi experimental design method, a number of catalysts was synthesized by the co-precipitation method, using different percentages of metal nitrate solution. The activities of the catalysts were determined by applying a laboratory scale continuous packed bed reactor. It was noted that the ZnO content of the catalyst, nature of precipitant agent, mass ratio of gamma-alumina to total metal oxides and calcination temperature, had the highest impact on the activity of the catalysts.
