Abstract

Characteristics of the reduction reactions between transition metal oxide oxygen carriers (OCs) including MnO

/Al

and CuO/Al

prepared by an impregnation method and CO in converter off-gas were investigated using a fixed bed reactor and a thermogravimetric analyzer. Surface area analysis

pulse chemisorption and scanning electron microscopy were used to characterize the cycle life performance of CuO/Al

. The results show that CuO/Al

exhibit the best reactivity among the three OCs

and the CO conversion at the reaction time of 2 min reach 90% when the reaction temperature is 225℃ or higher. Moreover

CuO/Al

can maintain the high and stable performance of CO removal and mechanical strength at 350℃

a gas hourly space velocity (GHSV) of 4000 h

-1

in the reduction reaction and a GHSV of 159 h

-1

in the oxidation reaction

exhibiting an excellent redox cycle life. Based on these findings

a new process based on CLC has been proposed

with which the intermittently discharged converter off-gas can be safely utilized

thereby achieving the continuous heat supply to users.
