The redox kinetics of a Fe–Cu-based oxygen carrier at 450–600° C was measured under
the fluidization state just like an actual chemical looping combustor, using a microfluidized …

Chemical looping combustion (CLC) of coal has gained increasing attention as a novel
combustion technology for its attractive advantage in the inherent separation of CO 2. In …

Chemical looping gasification (CLG) is an efficient coal gasification method and an
emerging technology. In this process, the oxygen is from oxygen carriers such as CuO …

Searching for naturally occurring minerals/ores which can only be crushed down and sieved
before they are used as oxygen carrier materials (OCM) is one of the main quests of the …

The CLOU performance of the CaTi x Mn 0.9− x Mg 0.1 O 3 (CMTM) perovskite-type system
was investigated, comparing materials produced at laboratory scale with those made at …

CuO-CaSO 4 based materials are widely used in chemical looping technology. Although the
reduction process is essential, the regeneration process of the oxygen carrier is also vital …

Chemical looping combustion (CLC) by direct use of coal as fuel has gained great
recognition for the great advantage for CO2 capture, but sulfur occurrence and evolution in …

In this paper five bimetallic Fe2O3‐MnO2 oxygen carriers supported on TiO2 were
evaluated for direct hard coal combustion via chemical looping path. The oxygen carriers …

Chemical looping with oxygen uncoupling (CLOU) is a promising technology due to its
potential to reduce energy efficiency penalty and cost associated with CO 2 capture. In this …
