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

摘要

The invention relates to saponite-derivatives according to the general formula Ax/nn+ [(Mg3-yMy) (Si4-xAlx)010(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 represent a number from 0 to 1.8. The invention also relates to methods for preparing such saponite-derivatives, catalytically active system based on such saponite-derivatives and their use in various hydrocarbon conversion processes.
