The preparation of composite crystalline silicates

A composite crystalline iron- and/or gallium-containing silicate is prepared by maintaining an aqueous starting material comprising one or more iron and/or gallium compounds, one or more silicon compounds optionally one or more aluminium compounds, and a diaminoalkane at an elevated temperature unti...

Beschreibung
Zusammenfassung:	A composite crystalline iron- and/or gallium-containing silicate is prepared by maintaining an aqueous starting material comprising one or more iron and/or gallium compounds, one or more silicon compounds optionally one or more aluminium compounds, and a diaminoalkane at an elevated temperature until the composite silicate is formed and separating the silicate from the mother liquor. Use thereof in a catalyst composition, especially for the dewaxing of hydrocarbon oils.
