Pillared clay catalysts for converting heavy oil or residual feedstock into maximum ethylene, propylene and butylene products comprises 30-75 wt % special pillared clays prepared by aluminum pillaring agents of high alkaline degree, 10-40 wt % inorganic oxide bonding agents, 0-30 wt % ZRP series high silicon zeolites with pentasil structure or Y-type zeolites, 0-10 wt % modified compositions of Mg, Al, K, P, Sn and polyethylene gycol, or 0-50 wt % Kaolinite matrix. The catalysts are prepared by mixing slurries, spray drying to form microspheric shapes, pillaring reaction and adding modified components. The catalysts have high catalytic activities, good light olefin selectivities and attrition resistance index. The products are suitable to be used as catalysts for hydrocarbon conversion, including CPP-catalyst for catalytic pyrolysis processes to convert heavy oil into ethylene and propylene, MIO-catalyst for yielding more isobutene and isoamylene products, and FCC-catalyst for yielding more gasoline and light cycle oil from heavy oil or residual feedstock, and also as adsorbents or catalyst carriers.
