Abstract: This paper addresses the cleaning challenges of sticky material on the inner walls of enamel stirred reactors during catalyst production. It provides an in-depth analysis of the negative impacts of material residue on production efficiency and product quality. Based on practical production requirements, an optimized cleaning method was proposed and a self-cleaning system was designed. The research outcome has successfully resolved the challenge of clea-ning sticky material on the walls in enamel stirred reactors. This solution offers broad applicability to solid-liquid two-phase reactors and demonstrates high promotion value in the petrochemical industry.
