Dicalcium ferrite: A chemical heat pump in integrated carbon capture and chemical looping combustion for the steel industry (2024)
Journal Article

An integrated calcium and chemical looping combustion using dicalcium ferrite (Ca2Fe2O5, C2F), a mixed phase from iron and calcium oxides, is proposed here to remove carbon (CO + CO2) contained in the blast furnace gas from the steel industry. C2F is... Read More about Dicalcium ferrite: A chemical heat pump in integrated carbon capture and chemical looping combustion for the steel industry.

Kinetic and Thermodynamic Enhancement of Low-Temperature Oxygen Release from Strontium Ferrite Perovskites Modified with Ag and CeO2 (2023)
Journal Article

The redox behavior of the nonstoichiometric perovskite oxide SrFeO3−δ modified with Ag, CeO2, and Ce was assessed for chemical looping air separation (CLAS) via thermogravimetric analysis and by cyclic release and uptake of O2 in a packed bed reactor...

The exploration of NiO/Ca2Fe2O5/CaO in chemical looping methane conversion for syngas and H2 production (2023)
Journal Article

Materials used for chemical looping can be exploited to process methane in a number of ways. Using the oxygen on the solid material leads to partial or total oxidation, whilst methane cracking to carbon on the depleted solid can produce hydrogen. Reg...

Understanding the Behavior of Dicalcium Ferrite (Ca2Fe2O5) in Chemical Looping Syngas Production from CH4 (2022)
Journal Article

Previous work on calcium ferrites showed they were able to convert syngas to hydrogen via chemical looping. The mixture of iron and calcium and their oxides has different thermodynamic properties than iron oxide alone. Here, the use of methane, an ab...

H2 production from a plasma-assisted chemical looping system from the partial oxidation of CH4 at mild temperatures (2019)
Journal Article

A plasma-assisted chemical looping system for the production of H2 (PCLH) was investigated in this study. This system allows the partial oxidation of CH4 at mild temperatures (573–773 K). Four active oxygen carriers: Fe2O3, NiO-impregnated Fe2O3 (NiO... Read More about H2 production from a plasma-assisted chemical looping system from the partial oxidation of CH4 at mild temperatures.

Pyrolysis of wood pellets in the presence of oxygen carriers in a fluidised bed coupled with a DBD reactor for tar quantification (2018)
Journal Article

The pyrolysis of wood in the presence of chemical looping agents including Fe2O3, mayenite-supported CuO and mayenite-supported Cu2O was studied from 773 to 1173 K. A continuous tar quantification system, based on a DBD reactor downstream of the flui...

H2 production from partial oxidation of CH4 by Fe2O3-supported Ni-based catalysts in a plasma-assisted packed bed reactor (2018)
Journal Article

H 2 -rich gas production from CH 4 at mild temperature (673K), was achieved in a single step without introducing a separate oxygen stream. This was conducted in a plasma-assisted packed bed reactor in the presence of Ni-based catalysts doped on an ac...
