Abstract: | Activated carbons containing different surface functionalities have been investigated as catalysts in conversion reactions
of ethanol and methanol. These carbon materials were prepared from Polish brown coal by chemical activation with potassium
hydroxide and modified by the oxidation or reaction with ammonia or chlorine. The main process upon ethanol decomposition
was its dehydrogenation, while in the process of methanol decomposition only a few samples were catalytically active, and
the only product was dimethyl ether (a product of dehydration).
