Popis:	1. The hydroxylic coating of decationized zeolites L is formed in the 300–450°C interval, and dehydroxylation takes place at 450–520°C. 2. The influence of the temperature of activation of decationized zeolites L on their activity in the cracking of octanes and the isomerization of o-xylene is directly connected with the formation and breakdown of the hydroxylic coating. 3. An increase in the degree of exchange of potassium ions by ammonium cations increases the selectivity of zeolite L in the cracking of octanes.
