Abstract of the disclosure: The invention provides boro-aluminosilicates having a zeo-lite structure, a process for their manufacture, and their use. For their manufacture, a mixture of silicon, aluminum, boron, sodium, potassium and tetramethylammonium compounds and water is prepared in a specific quantitative ratio, and heated in a closed vessel. The boro-aluminosilicates are used as catalysts in the manufacture of hydrocarbons, especially C2-C4-olefins, from methanol. |
