Biomass chemical looping gasification for high-quality syngas: A critical review and technological outlooks

Biomass chemical looping gasification (BCLG) offers significant advantages over the conventional biomass gasification process in terms of enhanced gasification efficiency, inherent CO₂ capture, process circularity, and mitigated emissions of pollutants. This review discusses the prevailing status of research and development of BCLG...

Modelling of Grain Boundary Segregation for Nanocrystalline Alloys: Applied to Pd-based Alloys

The Pd-based metal membranes have been focused on many studies, because they are the most promising candidates for hydrogen separation. If Pd-based membranes are designed in nanoscale, then the introduced high volume fraction of grain boundaries can act as fast diffusion paths for hydrogen atoms that leading to an increase of hydrogen separation...

Modelling CO2 Foam Displacements for Enhanced Oil Recovery

Increasing demand for oil in the near future implies the need for Enhanced Oil Recovery (EOR) methods to produce the remaining oil after primary and secondary production. Miscible gas injection has an excellent microscopic sweep efficiency; however due to density difference, high gas mobility and reservoir heterogeneity, the macroscopic sweep...
