Abstract: As an important medium affecting chemical reaction, catalyst is widely used in all walks of life around the world. The loading quality of catalyst directly affects the technical and economic indicators and the catalytic effect of production units. In recent years, fixed bed reactor has been widely used in gas-solid reaction and liquid-solid reaction process in petrochemical industry. The loading quality of catalyst directly affects the long-term and stable operation and the service life of catalyst. This paper summarizes and combs the methods of manual loading, dense phase loading, mechanical loading and intelligent loading used in fixed bed reactor catalyst loading. It analyzes the advantages and disadvantages of different methods. Then according to the analysis results and the current trend, the paper puts forward countermeasures and suggestions for improving catalyst loading equipment to improve catalyst loading quality so as to provide certain theoretical basis for realizing intelligent loading of fixed bed catalyst.

Key words: fixed bed reactor, catalyst loading, conventional loading, intelligent loading
