REACTOR FOR CONTROL OF COKE CONTENT, AS WELL AS DEVICE AND METHOD FOR OBTAINING LOW-CARBON OLEFINS FROM OXYGEN-CONTAINING COMPOUND Russian patent published in 2023 - IPC B01J8/00 B01J8/18 B01J8/22 B01J8/26 C07C11/22 C10G3/00 

FIELD: methanol processing.

SUBSTANCE: group of inventions is related to a reactor for coke content control, as well as to a device and method for producing low-carbon olefins from an oxygen-containing compound. The reactor (1) contains the shell (1-1) of the reactor, the reaction zone I and the catalyst deposition zone with the controlled coke content. Moreover, the shell (1-1) of the reactor contains the upper shell of the reactor and the lower shell of the reactor, while the upper shell of the reactor covers the deposition zone of the catalyst with a controlled coke content, and the lower shell of the reactor covers the reaction zone I. Furthermore, the reaction zone I communicates with the deposition zone of the catalyst with controlled coke content, and the cross-sectional area at any position of the reaction zone I is less than the cross-sectional area at any position of the deposition zone of the catalyst with controlled coke content. In addition, n separators (1-3) are installed in the reaction zone I in the vertical direction, the lower parts of the n separators are connected to the lower part of the reactor to control the coke content, the upper parts of the n separators are located in the catalyst deposition zone with a controlled coke content, and the n separators divide the reaction zone I into m subzones of the reaction zone I, where m and n are integers, and each of the separators have a hole for circulation of the catalyst so that the catalyst flows in the reaction zone I in a predetermined manner.

EFFECT: development of a reactor, a device and a method in which it is possible to effectively use a catalyst with a high productivity of methanol processing and high selectivity for low-carbon olefins.
