Abstract

The invention discloses a catalyst hydrothermal ageing device and an ageing method. The device comprises a water measuring system, a fluidizing gas system, ageing reactors, a liftable heating system and a condenser; an outlet of the water measuring system is communicated with an outlet of the fluidizing gas system and then is communicated with a feeding pipe of each ageing reactor; a gas outlet pipe of each ageing reactor is communicated with an inlet pipe of the condenser; the number of the ageing reactors is more than or equal to 2; each ageing reactor comprises a settling section, an ageing section and a pre-distribution section from top to bottom; each ageing reactor comprises a reactor top cover and a reactor cylinder body; a plurality of gas outlet pipes are formed in the reactor top cover; filters are arranged in the gas outlet pipes; the cross sectional area of each reactor cylinder body is gradually shrunk from top to bottom. The device can perform hydrothermal ageing treatment on a plurality of samples simultaneously and improves the catalyst hydrothermal ageing efficiency.

Description

technical field [0001] The invention relates to a multi-sample parallel catalyst hydrothermal aging device, in particular to an aging device for evaluating the hydrothermal stability of molecular sieves and catalysts for catalyst aging in a laboratory. Background technique [0002] Catalysts are widely used in the field of petrochemical industry. With the long-term operation of industrial devices, the activity of catalysts is dynamically stabilized within a fixed activity range. However, fresh catalysts are not representative due to their high initial activity and instability due to no deactivation process. Taking catalytic cracking catalyst as an example, when evaluating fresh catalyst in the laboratory, it is necessary to manually reduce the activity of the catalyst to the activity range of the industrial equilibrium catalyst, but the deactivation of the catalyst in the industrial device is a slow process, and the laboratory research needs to be quickly To reduce the acti...
