Abstract:
Conclusions
1. Thermal steam treatment of ZSM zeolites leads to their dealuminization, but the crystal structure is retained.
2. When the steam-treatment temperature is increased to 600°C, as a first step aluminum is lost from the cation positions and probably from the locations where it is concentrated in the framework; this leads to a reduction in secondary reactions and hydrogen transfer reactions and, as a result, to an increase in the resistance of the zeolite to coking.
3. When the steam-treatment temperature is increased to 600°C, the overall number of active centers falls sharply and hence also the degree of conversion of methanol to hydro-carbons. The active centers which remain are uniform.
