SUMMARY OR ABSTRACT
Text of Note
The reduction of a commercial Ni/usd\gammausdAl2O3 catalyst was carried out at temperature ranged from 250 to 500C and for duration from 2 to 16 hours. The effects of reduction conditions on the activity and selectivity of Ni/usd\gammausdAl2O3 were studied for a methanation reaction in a gradientless Berty reactor. These effects were used to determine optimal reduction conditions of the catalyst. The optimal reduction conditions are: temperature 300C, duration 8 hrs, space velocity 3000 hr, and heating rate of bed 5C/min. The effects of speed of impeller on the rate of methanation were studied and it was found that mass transfer limitations disappeared at a speed of 786 rpm. The effects of space-time, H2:CO ratio, and pressure on the activity and selectivity of the catalyst were studied. It is found that by increasing the space-time, the activity decreases while selectivity to CH4 formation increases from 90 to 96%. (Abstract shortened by UMI.)
