The alumina sol with high content of Al2O3 was prepared by acidolysis-peptizing with aluminum as an additive. Its physical and chemical properties were characterized by pH meter
rheometer
digital viscometer and zeta potential analyzer. Catalytic performance of catalyst that was prepared with alumina sol was evaluated through a fixed-bed. The results showed that the alumina content can reach 20% (mass) of the alumina sol sample with aluminum powder pH of 2.3. The alumina sol had good stability and chlorine was not higher than 15% (mass)
which can meet the FCC cracking catalyst requirements.
