Abstract
The influence of K2O on the amounts of chemisorbed hydrogen on a Ni catalyst, the catalyst activity and its resistance to coking were measured. Introducing potassium into the commercial catalyst (not into the support) appeared to enhance its resistance to coking. The best catalytic characteristics was noticed for a system containing ~0.5 wt. % K2O. The investigations show a good agreement between the resistance to coking obtained by the temperature-programmed reaction (TPReaction) method and by the traditional thermogravimetric method.
