Abstract:
The dielectric absorption spectrum of zeolite ZSM-5, in the range of frequencies 100 c - 10 Mc, was studied. The influence of the crystallization degree and influence of the Si/Al ratio on the amplitude of the dielectric absorption were analysed. It was observed that max depends on the Si/Al ratio in an exponential form. An excess of Et.OH in the mixture of crystallization influences favorably the kinetics of the process.
