原始语种摘要: Abstract(#br)Chemical Looping Combustion (CLC) of coal is an innovative combustion technology for CO 2 inherent capture, which uses oxygen carrier (OC) to transfer lattice oxygen to coal. However, coal gasification is the rate-limiting process for CLC of coal. Although carbon conversion and gasification rate are substantially improved with oxygen carriers in the presence of alkali additives, alkali loss in oxygen carrier is still a serious problem in the process of CLC of coal. The present work focuses on the OC–potassium interaction for two preparation methods of K-decorated OC. Different contents of catalyst (K 2 CO 3 ) were added into the preparation of Fe-based oxygen carrier by both co-precipitation and impregnation. And the effect of K-decorated methods on oxygen carriers was...
