Holistic assessment of oxygen carriers for chemical

This simple evaluation procedure was then compared with experiments in an 80 kW pilot plant. Ilmenite achieved the most stable operation, the highest temperatures and solid circulation rates. In addition, a carbon capture rate of over 98% and CO 2 yield of almost 90% was reached in the DFB. These results confirmed the assessment method …

This material has been classified during many cycles in the pilot plant, so that the probability of agglomeration and blockages is low. Another advantage is that highly cycled ilmenite is known to be more reactive than fresh material (Abad et al., 2011). The average diameter of the particles is d p(av,ilmenite) = 154 μm. Furthermore, an iron ...
