Abstract:
Abstract The objective of this work is to study the activities of mixed oxides containing cobalt oxide as catalyst for CO removal in reformed gas. The mixed oxides with varying amount of cobalt oxide were characterized for their specific areas, average pore diameters, chemical structure and average crystallite sizes. All samples were orepared by coprecipitation method. The BET results showed that the samples containing 8% cobalt oxide gave the highest specific surface area of 132.9 /g. Moreover, this catalyst showed the best performance to CO oxidation. CO completely converted to at 170 degree Celsius. However, an increase in amount of cobalt oxide in the catalysts led to decreasing of specific surface area and decreasing in the activity of the catalyst to the reaction
