Fluidized bed reactor and its application

Abstract

The invention relates to the field of fluidized bed reactors, in particular to a fluidized bed reactor and application thereof. The fluidized bed reactor comprises a reaction device and a catalyst extracting device configured on the reactor and used for extracting a catalyst online. By configuring the catalyst extracting device on the fluidized bed reactor body, the obtained reactor can achieve real-time and online catalyst extraction under the condition that a catalyst reaction does not need to be interrupted, operation of the reaction is not damaged, and the property of the catalyst such asthe catalyst carbon deposition amount and species variation of carbon deposition, can be monitored in real time.

Description

technical field [0001] The invention relates to the field of fluidized bed reactors, in particular to a fluidized bed reactor and its application. Background technique [0002] Fluidized bed reactors are very common in the field of petrochemical industry, mainly used for catalytic cracking of heavy oil, which can be divided into riser type and bed type, and are currently widely used in most methanol-to-olefins process technologies. In the reaction of methanol to olefins, catalyst is one of the most important core technologies. Therefore, it is necessary to study the amount of carbon deposition and the change of carbon deposition species in the catalyst during the reaction process, and it has high guidance for the design of more efficient catalysts in the future. significance. The current fluidized bed reactors do not have the function of extracting the catalyst online. The catalyst can only be taken out of the reactor after the reaction is interrupted or finished, and the t...

AI Technical Summary

Problems solved by technology

The current fluidized bed reactors do not have the function of extracting the catalyst online. The catalyst can only be taken out of the reactor after the reaction is interrupted or finished, and the temperature can only be analyzed at one time point. The efficiency is low. Facilitate the detection and analysis of multiple catalyst samples and the screening of catalysts
