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 formulaA$\genfrac{}{}{0ex}{}{\text{n+}}{\text{x/}}\mathop{\mathrm{image}}$_n[(Mg_3-yM_y)(Si_4-xAl_x)O₁₀(OH_2-z)F_z]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.
