摘要

采用添加适量铝粉的酸解-胶化工艺制备铝溶胶

采用pH计、旋转流变仪、纳米粒度与zeta电位仪等对铝溶胶的理化性质进行表征，用制得的铝溶胶样品制备成催化剂进行固定床反应评价。结果表明：采用添加适量铝粉的酸解-胶化工艺制得的铝溶胶氧化铝质量分数可达20%，氯质量分数不高于15%，pH为2.3，溶胶稳定性良好，可以满足FCC催化剂的实际使用要求。

Abstract

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.
