POROUS CERAMIC SPHERICAL BODY AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a porous ceramic spherical body which has high mechanical strength while maintaining properties required as a catalyst carrier and a method of manufacturing the same. SOLUTION: The porous ceramic spherical body characterized in that the volume of pores having a pore radius 1.8 nm to 100 μm is >=0.25 cm<3> /g, the mode of the fine radius exists in a range from 1 to 6 μm and the packing density is 0.7 to 1 g/cm<3> .
