Abstract
The duration of stable catalytic action (DSA) in methanol transformation on ZSM-type zeolites with the ratio of SiO 2 Al 2O 3 from 24 to 280, synthesized in the presence of quaternary ammonium bases, has been determined. The DSA is shown to decrease with increasing aluminum content of zeolites, while the yield of aromatic hydrocarbons products increases. From NMR 27Al and 29Si data it was concluded that the formation of nondesorbed compounds proceeds on the centers of multipointed adsorption, including more than one aluminum atom. And probably one of them is in extraframework (cation) position.
