Abstract
Stable pillared interlayered clay compositions are prepared by reacting smectite type clays with polymeric cationic hydroxy metal complexes of metals such as aluminum, zirconium, and/or titanium. These novel interlayered clay compositions which possess substantial surface area in pores of less than 30 A in diameter are used as catalysts, catalytic supports, and sorbents.
