ABSTRACT:
A class of highly stable supergallery pillared clay compositions that have a basal spacing up to 55 .ANG. corresponding a gallery height of 35 .ANG. for samples dried at room temperature and a basal spacing up to 45 .ANG. corresponding a gallery height of 255 .ANG. for samples steamed at 800.degree. C. for 17 hours. Said compositions are prepared by special procedures including pillaring reaction in presence of poly (vinyl alcohol) as a pillaring precursor, an aging process at pH of around 4 to 9, and a calcinating or steaming treatment at high temperature. The new compositions exhibit catalytic properties and adsorption properties superior to prior art pillared clays. Said compositions are useful as catalysts for carbonium-ion reaction, and as adsorbents and catalyst carriers. They are especially suitable for preparing microspheric cracking catalysts for heavy oil or residual feedstock.
