ABSTRACT:
Delaminated clays whose X-ray diffraction patterns do not contain a distinct first order reflection are prepared from synthetic and natural swelling clays whose particles have a length-to-width ratio greater than about 2.0, a length-to-thickness ratio greater than about 5.0 and are comprised of randomly oriented platelets by reacting the clay with a pillaring agent selected from the group consisting of polyoxymetal cations, mixtures of polyoxymetal cations, colloidal particles comprising alumina, silica, titania, chromia, tin oxide, antimony oxide or mixtures thereof, and cationic metal clusters comprising nickel, molybdenum, cobalt or tungsten and then subjecting the resulting reaction products to drying in a gaseous medium, preferably spray drying. The resulting acidic delaminated clays, which contain the microporosity associated with zeolites and pollared clays and the macroporosity associated with amorphous aluminosilicates, may be used as the active component of cracking and hydroprocessing catalysts.
