Hydrogenation of carbon monoxide over coprecipitated iron-manganese catalysts in a pseudo slurry reactor
The hydrogenation of carbon monoxide to produce low-molecular-weight olefins has been investigated over unsupported iron-manganese catalysts with an approximate manganese-to-iron atomic ratio of 2:100. Temperature distributions in the following reactor modes have been studied: a conventional dense-bed reactor; a dense-bed trickle flow reactor; a dense-bed, pseudo slurry reactor; a diluted-bed reactor; a diluted-bed trickle flow reactor; and a diluted-bed, pseudo slurry reactor. A nearly isothermal temperature distribution was observed in the diluted-bed, pseudo slurry reactor. The n-hexadecane was determined to be a suitable heat transfer liquid for the diluted-bed pseudo slurry operation. The hydrogenation of carbon monoxide in a diluted-bed reactor over coprecipitated iron-manganese catalysts obeys the Schulz-Flory weight distribution law for hydrocarbons having a carbon number of up to 15. A higher chain growth probability was observed for hydrocarbons with carbon numbers greater than 15. A complete process variable investigation was conducted in the diluted-bed reactor and in the diluted-bed, pseudo slurry reactor using n-hexadecane as the heat transfer liquid. The process variables investigated were reaction temperature, reactor pressure, H/sub 2//CO ratio, and reactant gas space velocity. The results of this investigation agreed with the data reported in the literature.
