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.}, keywords = {}, url = {https://scientiairanica.sharif.edu/article_2852.html}, eprint = {https://scientiairanica.sharif.edu/article_2852_7944f2deac0add21abca0dea7ecaf1cc.pdf} }
