Abstract

The effect of temperature of calcination of Co catalysts reduced at 400°C on their characteristics (the surface area, degree of reduction, particle size, and average crystallite diameter), was investigated. It was found that an increase in the calcination temperature from 400 to 500°C significantly affects the size of cobalt crystallites. Based on these data, a method for predicting the catalyst stability is proposed.
