Example Embodiment

[0016] [Example 1]

[0017] In such figure 1 On the reaction device shown, the tops of the regenerator, the first reactor, and the second reactor are all provided with gas outlets, and a catalyst filter is set before the gas outlet. The catalyst flow control valve is a plug valve, and the catalyst flow control valve outlet is connected to the second reactor. The dense phase section of a reactor is connected, the riser outlet is connected with the dilute phase section of the regenerator, and a catalyst feeding pipeline is arranged on the top of the regenerator. The operating pressure of the device is normal pressure (gauge pressure), the catalyst adopts SAPO-34, the first raw material adopts a mixed hydrocarbon with carbon four or more, and the content of carbon four olefin is 88% by weight, and the second raw material adopts methanol with a purity of 99.5%. The regeneration medium is air, the regeneration temperature is 650℃, the reaction temperature of the first reactor is 550℃...

Example Embodiment

[0018] [Example 2]

[0019] According to the conditions and steps of Example 1, except that the first raw material uses methanol with a purity of 99.5%, the second raw material uses steam, the second reactor is used as a stripper, and the reaction temperature of the first reactor is 470°C. Airspeed is 4.2 hours -1 The mass fraction of carbon deposit on the catalyst coming out from the bottom of the first reactor is 4.3%, which enters the riser after being stripped, and the carbon-based yield of ethylene and propylene in the gas phase product is 81.28% by weight.

Abstract

The invention relates to a reaction device for fluidized bed catalyst performance evaluation, which mainly solves the problems that during the fluidized bed catalyst performance evaluation, the device form is single, and the purpose can not be flexibly regulated. The reaction device for the fluidized bed catalyst performance evaluation adopts the technical scheme that the reaction device mainly comprises a regenerator 4, a first reactor 10, a second reactor 15 and a lifting pipe 12, wherein the lower part of the regenerator 4 is connected with an inlet of a catalyst flow rate control valve 6, an outlet of the catalyst flow rate control valve 6 is connected with the first reactor 10, the lower part of the first reactor 10 is connected with an inlet of a catalyst flow rate control valve 13, an outlet of the catalyst flow rate control valve 13 is connected with the second reactor 15, the lower part of the second reactor 15 is connected with an inlet of a catalyst flow rate control valve 17, an outlet of the catalyst flow rate control valve 17 is connected with an inlet of the lifting pipe 12, and an outlet of the lifting pipe 12 is connected with the regenerator 4. The problems are perfectly solved, and the reaction device can be used in the fluidized bed catalyst evaluation.

Description

technical field [0001] The invention relates to a reaction device for evaluating the performance of a fluidized bed catalyst, in particular, it is used in the performance evaluation of a fluidized bed catalyst with a deactivation rate of minute order. technical background [0002] At present, the fluidized bed reaction process has been widely used in petrochemical, coal chemical, fine chemical and other fields. Due to its advantages of easy temperature control, easy continuous regeneration of rapidly deactivated catalysts, and easy realization of large-scale production, the fluidized bed The application in the chemical industry has gained more and more attention. [0003] The fluidized bed reaction-regeneration process is widely used in the field of catalytic cracking (FCC). Because the deactivation speed of FCC catalyst is very fast, which belongs to second-level deactivation, FCC basically uses riser reactors at present, and the deactivated FCC catalyst is regenerated.
