Abstract:
The formation of coke on active sites in the entire volume of zeolite Y crystals has been experimentally confirmed. However, complete deactivation in the case of decationated zeolites is due to the blocking of zeolite space by coke deposition on the outer surface of the crystals. In this case, blocking occurs long before complete poisoning of the active sites in the bulk and filling the large cavities of zeolite Y with the coke. The model of the “inner” deactivation of zeolites Y is applicable only to dealuminated zeolites with a silica ratio equal to or greater than 70–75 or in the case of selective dealumination of the outer surface of the zeolite crystals.
