Novel Method for Generating Large Mesopores in an Amorphous Silica–Alumina by Controlling the Pore Size with the Gel Skeletal Reinforcement and Its Catalytic Cracking Properties as a Catalyst Matrix

Abstract

Abstract The pore size of amorphous silica and silica–alumina with large mesopores was controlled for the first time in the range of 5 to 30 nm by gel skeletal reinforcement. The conversion and the ratio of multi-branched to single-branched products increased with increasing the pore diameter of silica–alumina in catalytic cracking of n-dodecane with its use as a matrix.
