Japan, Sept. 18 -- JGC CATALYSTS & CHEMICALS LTD has got intellectual property rights for 'POROUS SILICA-ALUMINA PARTICLE, AND METHOD OF PRODUCING THE SAME.' Other related details are as follows:
Application Number: JP,2022-043689
Category (FI): C01B33/18@Z,C01B33/12@A,C01F7/141
Stage: PROBLEM TO BE SOLVED: To provide porous silica-alumina particles having a high ratio of pores of a relatively large diameter in the whole pore volume and including crystalline boehmite alumina.SOLUTION: The porous silica-alumina particles including crystalline boehmite alumina, are characterized in that a specific surface area SA measured by a BET method is in a range of 400 to 600 m2/g, a pore volume PV measured by a BJH method is in a range of 1.0 to 2.2 ml/g, a ratio P10 of a pore diameter PD measured by the BJH method with respect to the whole pore volume PV with the pore volume of 10 nm or more, is in a range of 60% or more, and a mass ratio S/A of silica relative to alumina is in a range of 2/98 to 70/30.SELECTED DRAWING: None (Grant)
