CATALYST PREPARATION FOR CO2 Utilization IN REFORMING OF METHANE

The effect of using different supports, additives and changing residence time on conversion of carbon dioxide and hydrogen yield through dry reforming reaction was explored experimentally. The supports used are alumina, silica, titania and zirconia . Cerium and Cobalt were used as additives. Two F/W values were used 3.33 and 33.33 ml./min.gm.cat. The catalysts were prepared by impregnation method and tested at atmospheric pressure, total feed rate of 10 ml/ min. of equimolar feed gases and temperature range of 773- 848 K. The results showed that high surface area alumina was the best support in terms of both activity and stability . Both additives promoted the performance of the catalysts , Cerium gave much higher promotion in carbon dioxide conversion and hydrogen yield than Cobalt
