TL;DR: In this article, an environmental evaluation of the Chemical Looping Combustion (CLC) process for natural gas based on Life Cycle Assessment (LCA) was presented, where five different oxygen carrier materials already tested in pilot plants were considered and the results compared to the conventional natural gas combustion in a gas turbine in a combined cycle without and with CO2 capture using postcombustion capture with amines.

TL;DR: In this paper, the behavior of the Mn-ore during continuous combustion of a bituminous coal in a 0.5kW CLC unit was evaluated and the effect of the main operating variables -such as fluidizing medium, oxygen carrier circulation rate, temperature, and solids inventory in the fuel reactor - on the combustion efficiency and CO 2 capture was investigated.

TL;DR: In this paper, the type of oxygen carrier employed plays a vital role in CO2 separation in a chemical-looping combustion (CLC) system. But, it is not a suitable carrier for CO2 separator.

TL;DR: In this paper, a perovskite (CaMn0.775Mg0.1Ti0.125O2.9-δ) material was evaluated during its in-situ activation under determined operating conditions in a 0.5 kWth CLC pilot plant.

TL;DR: Sulfidation experiments at atmospheric pressure in a thermogravimetric analyzer were performed with two calcined limestones and a fully calcined dolomite at temperatures between 450 and 700 °C and with sorbent particle sizes between 0.4 and 1.6 mm as discussed by the authors.
