Title:
PROCESS FOR PRODUCING HYDROGEN BY FULL-TEMPERATURE-RANGE SIMULATED ROTARY MOVING BED PRESSURE SWING ADSORPTION (FTRSRMPSA) ENHANCEMENT REACTION OF SHIFTED GAS
Document Type and Number:
WIPO Patent Application WO/2023/173768
Kind Code:
A1
Abstract:
Disclosed in the present invention is a process for producing hydrogen by a full-temperature-range simulated rotary moving bed pressure swing adsorption (FTrSRMPSA) enhancement reaction of a shifted gas. A multi-channel rotary valve is placed in the center, a plurality of axial flow fixed bed adsorption reactors loaded with a medium and low temperature conversion catalyst and an adsorbent in a mixed manner are provided on a circular rotary tray at the periphery of the multi-channel rotary valve and are connected by means of pipelines, and the rotation direction and rotation speed (ω1) of the rotary valve and the rotation direction and rotation speed (ω2) of the circular rotary tray are adjusted and controlled, such that a gas flowing through adsorption reaction bed layers completes mass transfer and heat transfer of reaction-adsorption and desorption regeneration steps by continuously entering and leaving inlets and outlets of respective adsorption reactors while each adsorption reaction bed layer rotates, the simulated rotary moving bed pressure swing adsorption enhancement reaction process based on axial flow fixed bed pressure swing adsorption is realized, a hydrogen (H2) product gas is directly obtained therefrom, the purity is greater than or equal to 99.9-99.99%, the yield is greater than or equal to 92-95%, and meanwhile, a byproduct of high-purity carbon dioxide (CO2) is obtained.
