Abstract

The mean size of Co particles and the variance of distribution were shown to increase as the temperature of calcining grew. The size was maximum at a 400°C temperature of calcining and decreased somewhat at 500°C. The mean Co particle size decreased in the presence of Pt, and the particle-size distribution narrowed. A decrease in the mean particle size in the Co/Pt/Al2O3 catalyst increased selectivity with respect to methane and decreased selectivity with respect to C5+.
