Question

8-9 Two samples of silica-alumina cracking catalysts have particle densities of 1.126 and 0.962 g/cm³, respectively, as determined by mercury displacement. The true density of the solid material in each case + H. L. Ritter and L. C. Drake, Ind. Eng. Chem., Anal. Ed., 17, 787 (1945). 358 CHEMICAL ENGINEERING KINETICS is 2.37 g/cm³. The surface area of the first sample is 467 m²/g and that of the second is 372 m²/g. Which sample has the larger mean pore radius?
