Description Of A Method To Produce Catalysts Based On Iron Group Metals
A method is suggested to produce catalysts based on iron group metals especially suitable for gasoline synthesis by the Fischer-Tropsch reaction. The catalyst is produced by reducing oxides and hydroxides of the metals of the specified group, using the drying at slowly increasing temperature up to the reducing temperature. The catalyst is reduced at 200-450°C and then cooled. The cooling is carried out in the atmosphere of hydrogen and carbon monoxide and finalized in the atmosphere of carbon dioxide. Thus reduced catalyst shows the (CO + H2) conversion slightly exceeding that of the Fischer catalyst in the reaction carried out a temperature of 195-200°C. The catalyst saturation with carbon dioxide prevents the catalyst firing at the contact with air.
