Abstract
A pilot plant for chemical looping hydrogen generation using a single-column packed bed and hydrogen generation method. The plant has a feeding system, reaction system, tail gas treatment and analysis system, and auxiliary system. The reaction system has a packed bed reactor, inside which a thermal storage layer, oxygen carrier layer and supporting layer are arranged successively from top to bottom. The feeding system has a delivery pipe, metering pump, mass flow controller and fuel mixer. The tail gas treatment and analysis system has a cooler, gas-liquid separator, mass flow meter, gas analyzer and tail gas pipe. The packed bed reactor is subjected to fuel reduction, purge, steam oxidation, purge, air combustion and purge stages successively under control of the feeding system. The pilot plant enables evaluation for oxygen carriers and identification for technological difficulties and can generate high-purity hydrogen without using complex gas purification devices.
