Description

technical field [0001] The invention relates to a device for hydrothermal treatment of shaped catalysts and evaluation of fixed fluidized bed catalysts. Background technique [0002] For reactions with strong exotherm and catalysts that are prone to deactivation, fluidized bed reactors are often used in industry to evaluate catalyst performance such as catalyst activity, selectivity and wear resistance. The fluidized bed reactor has the following advantages: the fluidized fine powder particles are in contact with the fluid in a suspended state, the fluid-solid phase interface area is large, and the utilization rate of the catalyst is improved; the particles are mixed violently in the bed, so that the particles The temperature and concentration in the bed are uniform and consistent, and the thermal stability is high, which is conducive to the isothermal operation of strong exothermic reactions; the particles in the fluidized bed have properties similar to fluids, and can be r...
