Catalytic Activity of Cobalt-Molybdenum in Gas-Phase Ketonisation of Pentanoic Acid
Ketonisation of pentanoic acid was carried out over cobalt-molybdenum and its supported catalysts in the gas-phase using fixed-bed reactor at 320-420°C and atmospheric pressure. Bulk Co-Mo and its supported catalysts were active in the ketonisation of pentanoic acid. 20%Co-Mo/Al2O3 showed the best catalytic performance in comparison to other supported catalysts. It gave 95% 5-nonanoe selectivity at 91% of pentanoic acid conversion at 308°C and ambient pressure for 5h time on stream (TOS). 20%Co-Mo/Al2O3 catalyst was stable for 15h TOS with small catalytic deactivation. All catalysts used in this study were characterized by different techniques such as TGA analysis, BET surface area and porosity, the catalysts acidity was measured in this work by using FTIR spectroscopy.
