Pilot plant for chemical looping hydrogen generation using single-column packed bed and hydrogen generation method

A pilot plant for chemical looping hydrogen generation using a single-column packed bed, wherein the plant comprises a feeding system, a reaction system and an tail gas treatment and analysis system;

• wherein the feeding system comprises at least one raw material delivery pipe, at least one raw material mass flow controller and a fuel mixer, wherein at least one outlet of the raw material mass flow controller is connected with an inlet of the fuel mixer, and other remaining outlets of the raw material mass flow controller are connected with an inlet of the reaction system;
• the reaction system is composed of a packed bed reactor, inside which a thermal storage layer, an oxygen carrier layer and a supporting layer are arranged successively from top to bottom, and the packed bed reactor is continuously subjected to fuel reduction, first purge, steam oxidation, second purge, air combustion and third purge stages successively under the control of the feeding system;
• and
• the tail gas treatment and analysis system comprises a cooler, a gas-liquid separator, a mass flow meter, a gas analyzer and a tail gas pipe in successively connection by the outlet to inlet.
