Title:

LIQUID-SOLID AXIAL MOVING BED REACTION AND REGENERATION DEVICE, AND SOLID ACID ALKYLATION METHOD

Document Type and Number:

WIPO Patent Application WO/2020/083279

Kind Code:

A1

Abstract:

A liquid-solid axial moving bed reaction and regeneration device, and a solid acid alkylation method using the liquid-solid axial moving bed reaction and regeneration device. The liquid-solid axial moving bed reaction and regeneration device comprises: an axial moving bed reactor (1), a spent catalyst receiver (5), a catalyst regenerator (4), and a regenerant receiver (6) which are sequentially connected; a catalyst outlet of the regenerant receiver (6) is communicated with a catalyst inlet of the axial moving bed reactor (1); the axial moving bed reactor (1) is provided with at least two catalyst bed layers (3) which are provided vertically, and the axial moving bed reactor (1) is provided with a feeding port (2) above each catalyst bed layer (3); a catalyst conveying pipe (16) is provided between two adjacent catalyst bed layers (3), so that a catalyst can move from top to bottom in the axial moving bed reactor (1); a separating member (10) is provided between two adjacent catalyst bed layers (3); an inside space of the separating member (10) is communicated with the catalyst conveying pipe (16), and the separating member (10) is used for separation of materials and the catalyst after reaction of the catalyst bed layers at the upstream; the catalyst separated by the separating member (10) moves downward by means of the catalyst conveying pipe (16).
