Impact of potassium on bio-ash slagging and resultant slag flowing characteristics under mild reducing environment

Tanvir Alam et al.

Summary: This study investigates the effect of potassium (K) on the flowability of bio-slag in a reducing gas environment at temperatures ranging from 900 to 1400 degrees Celsius. The flow rate of bio-slag was compared to that of coal slag using the inclined plate method. It was found that the presence of K2O and Al2O3 in bio-slag favors the formation of solid KAlSi2O6, resulting in a lower flow rate compared to coal slag, which is rich in CaO and Al2O3 and favors the formation of molten species. Additional K in bio-ash was found to enhance the flow rate, but it was still lower than that of coal slag due to the superiority of Ca2+ over K+ in promoting bio-slag flow. The use of CaO as a flux additive and monitoring the flow rates of bio-slag in low-angle locations within the furnace are recommended for practical applications.

Boosted carbon resistance of ceria-hexaaluminate by in-situ formed CeFexAl1_xO3 as oxygen pool for chemical looping dry reforming of methane

Qian Yang et al.

Summary: The potential for carbon deposition over metallic Fe0 severely hampers the enhancement of methane-to-syngas selectivity through chemical looping technology. However, the in-situ formed CeFexAl1_xO3 over ceria-hexaaluminate was found to greatly improve carbon resistance even in the presence of Fe0. This CeFexAl1_xO3/Fe0/hexaaluminate sandwich-like structure provided a convenient pathway for CeFexAl1_xO3 as an oxygen pool to supply sufficient oxygen for timely oxidation of carbon over adjacent Fe0, resulting in outstanding carbon resistance and high CH4 conversion.

Redox Performance of Cu-Doped Fe2O3/Al2O3 as Oxygen Carriers for Chemical Looping Hydrogen Production

Shuoxin Zhang et al.

Summary: The study found that copper doping enhanced the activities of iron-based oxygen carriers, but excessive copper would reduce their reactivity due to melting and agglomeration. Hydrogen temperature-programmed reduction (H-2-TPR) analysis, fixed-bed experiments, and density functional theory (DFT) calculations confirmed that Cu promoted the deep reduction of Fe2O3. The oxygen carrier doped with 1 wt % CuO was the most suitable material for CLH, with the highest hydrogen yield sustained at a high and stable level in multiple redox cycles.

Enhanced resistance to carbon deposition in chemical-looping combustion of methane: Synergistic effect of different oxygen carriers via sequence filling

Xianming Cheng et al.

Summary: Chemical-looping combustion (CLC) is a promising technology for CO2 capture with low energy consumption, but carbon deposition from methane poses a challenge. This study investigated carbon formation behaviors of four typical oxygen carriers (OCs) and proposed a strategy to eliminate carbon by arranging them in a fixed-bed reactor. The findings show that NiO/ZrO2 OC is prone to carbon formation, while CuO/SiO2 OC has high CH4 conversion and minimal carbon formation. Mixing these OCs in a suitable sequence can significantly enhance CLC efficiency and resistance to carbon deposition.
