TL;DR: In this article, the characteristics and gas product properties of pyrolyzing sewage sludge were determined, aiming to utilize efficiently the waste for energy recovery, where the activation energy was calculated at ∼30 kJ mol−1 in the first reaction stage for all the selected heating rates, and the preexponential factors increased with the increasing heating rate.

TL;DR: In this article, the reaction of CuFe2O4 with two Chinese coals of different ranks [Liu Pan Shui (LPS) sub-bituminous coal and Yang Quang (YQ) anthracite] was performed in a thermogravimetric analyzer (TGA).

TL;DR: In this article, the carbon deposition and sulfur evolution in chemical looping combustion with syngas were investigated using thermodynamic simulation, with focus on carbon deposition, and five metal oxides, such as NiO, CuO, Fe2O3, Mn3O4, and CoO, were selected as oxygen carriers for CLC application.

TL;DR: In this article, the authors investigated the performance of Ni-based oxygen carriers for CLC by coal char and showed that NiO/NiAl{sub 2}O{sub 4} starts to react with coal char rapidly.

TL;DR: In this article, the development of tailor-made oxygen carriers and active design of reactors at Huazhong University of Science & Technology is comprehensively reviewed and appraised, including the screening and optimization of oxygen carriers, reduction kinetics of oxygen carrier with gaseous fuels, microcosmic level understanding of the reaction mechanism in chemical looping via density functional theory (DFT) calculation, rational design and controllable synthesis of a hierarchically-structured oxygen carrier, and negative effects of pollutants (like sulfur and chlorides) on oxygen carriers.
