Pillared interlayered clay materials useful as catalysts and sorbents

摘要

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.
