| Abstract: | The large number of variables involved in the preparation of Raney copper-zinc catalysts for methanol synthesis were screened by statistical methods using a Plackett-Burman screening design. Three important variables, leach reaction temperature, leach digestion temperature and leach digestion time were further investigated using a central composite design. It was found that active Raney copper-zinc catalysts were produced using high (348-358?K) extraction temperature, low (298-318?K.) digestion temperature and long (70-80 min) digestion time |
