Summary: The study used CaO/Fe2O3 as a composite oxygen carrier for biomass chemical looping gasification (CLG), showing that adding CaO can significantly improve the quality of syngas and reduce greenhouse gas emissions. Various factors such as the ratio of Fe2O3 to CaO, steam to biomass, and oxygen carrier to biomass were found to affect the syngas composition, with temperature also playing a significant role in CLG gas yield. The possible reaction mechanism suggested that variations in Ca may be the main factor in gas composition fluctuation.

Summary: Operando spectroscopic techniques were used to investigate the impact of oxygenates deposition on the deactivation of cobalt on titania Fischer-Tropsch catalysts under high pressure. It was found that catalysts prepared via impregnation had more and heavier carboxylates, likely due to higher olefin content in the products, leading to increased formation of oxygenates. Gas chromatography/infrared spectroscopy data indicated that the surface carboxylate species were not involved in catalyst deactivation, serving as spectator species on the titania support.

Summary: This study investigates the copper promotion of chromium-doped iron oxide prepared via co-precipitation for high-temperature water-gas shift (WGS) catalysis. The results show that copper doping delays the formation of hematite in the fresh catalyst, facilitating the formation of small crystallites of ferrihydrite. Chromium is incorporated in the octahedral sites of the active magnetite phase, resulting in a partially oxidized structure. Copper promotion enhances the CO conversion under high-temperature WGS conditions.
