Title
Hydrogen chemisorption on rhenium-promoted γ-alumina supported cobalt catalysts
Abstract

The effect of the measurement conditions on the hydrogen chemisorption on CoRe/γ-Al2O3 has been studied systematically. The measurement temperature is one of the most important factors. In the range from 298 K to 433 K the amount of strongly adsorbed hydrogen increases, and remains stable up to 473 K. The difference observed is significant, the estimated cobalt dispersion is up to 20% higher at the higher temperatures. Different γ-alumina samples were examined, and the behaviour was similar for all the samples as well as for samples with different apparent particle sizes. The most effective evacuation temperature to remove the adsorbed hydrogen on cobalt before hydrogen chemisorption analysis was found to be the temperature used for catalyst reduction.
