CRYSTALLINE ALUMINOSILICATE ZEOLITES, A PROCESS FOR THEIR PREPARATION AND THEIR USE

摘要

of the disclosure: The invention relates to crystalline aluminosilicate zeolites, a process for their preparation and their use. To prepare these compounds, a mixture of silicon compounds, aluminum compounds, sodium compounds, potassium compounds, ammonium compounds and water in specified proportions is prepared, and this mixture is heated in a sealed vessel. The zeolites are used as catalysts in the preparation of C2-C4-olefins from methanol.
