Catalyst continuous cyclic regeneration methane catalytic cracking hydrogen production device and hydrogen production system

Abstract

The invention belongs to the technical field of methane catalytic cracking hydrogen production, and particularly relates to a catalyst continuous cyclic regeneration methane catalytic cracking hydrogen production device and a hydrogen production system. The hydrogen production device comprises a methane catalytic cracking reactor, a steam reforming regeneration reactor and a spiral conveyor, and the bottom of the methane catalytic cracking reactor is communicated with the steam reforming regeneration reactor through the spiral conveyor. A steam distributor is arranged in the steam reforming regeneration reactor, and the top of the steam reforming regeneration reactor is communicated with the top of the methane catalytic cracking reactor. Along with the catalytic cracking reaction, the deactivated catalyst settles to the bottom of the methane catalytic cracking reactor and is conveyed to the steam reforming regeneration reactor by the spiral conveyor, and steam upwards blown by the steam distributor is in contact with the deactivated catalyst, is regenerated and enters the catalytic cracking reactor again; a continuous cycle process of catalysis, inactivation, regeneration and catalysis is completed; the deactivated catalyst is regenerated through water vapor, so that potential safety hazards caused by oxygen entering are avoided.
