SYNTHETIC SAPONITE-DERIVATIVES A METHOD FOR PROPARING SUCH SAPONITES AND THEIR USE IN CATALYTIC (HYDRO) CONVERSIONS

摘要

The invention relates to saponite derivatives according to the general formula An+_x/n[(Mg3-yMy)(Si4-xAlx)O10(OH2-z)Fz ] wherein A represents an (alkyl-substituted) ammonium ion and/or any metal having basic or amphoteric properties, M represents a bivalent metal ion having an ionic radius between 0.050 and 0.085 nm, n represents the valence of A, x represents a number between 0.05 and 1.5, y represents a number between 0.05 and 2.95 and z represents a number from 0 to 1.8. The invention also relates to methods for preparing such saponite-derivatives, catalytically active systems based on such saponite-derivatives and their use in various hydrocarbon conversion processes.
