A packed-bed chemical-looping combustion (CLC) reactor is developed using syngas as fuel with ilmenite as an oxygen carrier. The aim of the current study is to analyze, design and optimize the performance of this novel reactor concept using numerical simulations. Transient 1-D reactor models of the fuel and air reactors have been developed to investigate the dynamic temperature and concentration profiles along the length of the reactor. Simulation studies show that a very high temperature air stream can be produced efficiently with packed-bed CLC using syngas combustion with ilmenite with intrinsic capture of CO2. On the other hand, due to the relatively low reduction rates, much more attention has to be paid to fuel slip during the reduction cycle.
