ABSTRACT:
This present invention includes a composition of matter made up of a kandite clay which has been treated with large molecules containing multi-atom metallic or semi-metallic species and heated to produce pillars within the clay which are located generally between the clay's layers. The pillared kandite composition is useful as a catalyst support, sorbent, or ion exchanger.
The present invention also includes a process for producing the pillared kandite composition comprises mixing the finely divided clay in an aqueous solution with the pillaring medium and heating the resulting composition at a temperature high enough to decompose the added compound.
