Fischer-Tropsch Reaction over Nano Alumina Supported Nickel Molybdenum catalyst

Nano alumina supported trinickelheptamoltbdate Ni3Mo7O24 multitransition-metal complex was prepared via impregnation method. The partial reduction of the pre-catalyst was performed in a batch reactor with hydrogen gas at a pressure of 40 bars and temperature of 873oK for 5 hours. The catalyst was characterized using XRD and BET.The nickel/molybdenum catalyst was employed for Fischer-Tropsch reaction. The evaluation occurred in a batch reactor at different temperature (423-623oK), over a pressure range of 5-30bars with the H2/CO ratio varying from 2 to 6. The catalyst wasactive and stable for use at moderate temperature and pressure. This catalyst gave a high conversion of carbon monoxide into a mixture of hydrocarbons (mainly gaseoushydrocarbons). The degree of carbon monoxide conversion increased with increasing temperature and pressure. Using the nickel/molybdenum catalyst, 46% of the carbon monoxide was converted into hydrocarbons in one half hour and 90% conversion occurred in 20 hours
