WERKWIJZE VOOR HET BEREIDEN VAN KRISTALLIJNE SILICATEN EN TOEPASSING VAN DE VERKREGEN SILICATEN ALS KATALYSATOR OF KATALYSATORDRAGER.

摘要

Novel crystalline silicates which in dehydrated form having the composition in terms of moles of the oxides: (1.0+/-0.3) (R)2/nO. [a Fe2O3. b Al2O3. c Ga2O3. y(dSiO2. eGeO2)], wherein R is one or more mono- or bivalent cations and a, b, c, d, e, y and n are as defined hereinafter are disclosed. The thermally stable silicates are suitably employed as extracting agents, drying agents, ion exhange agents, catalysts and catalyst carriers.
