Special Issue Information

Dear Colleagues,

Carbon capture utilization and storage (CCUS) could be the key to mitigating global warming and achieving near-zero emissions worldwide; one of its main focuses is how to realize low-cost and high-efficiency CO2 capture. Chemical looping combustion (CLC) is a representative technology for CO2 capture and is regarded as one of the most promising methods due to its inherent CO2 separation. In CLC, one key challenge is to develop a suitable chemical looping combustion reactor ensuring a high CO2 yield, combustion efficiency, and carbon capture efficiency. Various kinds of reactors with special configurations are applied to enhance the performance of chemical looping combustion reactors. The visualization and understanding provided by modeling and simulation, the immeasurable information (such as gas–solid phase flow, unconverted gas distribution, gas leakage routes) assist investigators in upgrading the design of the reactors, optimizing the operation parameters, scaling up the reactors, etc. All these contributions will elevate chemical looping technology to the next level.

This Special Issue will focus on “Chemical Looping Combustion Reactor and Its Applications”. Topics of interest for publication include but are not limited to:

  • Chemical looping combustion reactor design and operation;
  • Modeling and simulation of chemical looping process;
  • Pilot plants and microreactors;
  • Novel chemical looping technologies reactors;
  • Technoeconomic analysis on the CLC system.

Due to the more and more serious cyanobacteria bloom problem, it is particularly urgent to find a technology suitable for large-scale disposal and the efficient recovery of abundant nitrogen and phosphorus resources in cyanobacteria. The combination of chemical looping combustion (CLC) and biomass densification technology is thought to be a promising utilization selection. Based on the experimental results, the mechanical strength and energy density of briquette cyanobacteria are evidently increased with the compressive load; whereas, 10% is the optimal moisture content in the densification process. A higher heating rate in TGA would result in the damage of the internal structure of the briquette cyanobacteria, which are conducive to the carbon conversion efficiency. The presence of a hematite oxygen carrier would enhance the carbon conversion and catalyzed crack liquid products. CO2 yield is increased 25 percent and CH4 yield is decreased 50 percent at 900 °C in the CLC process. In addition, the lower temperature and reduction atmosphere in CLC would result in a lower NO emission concentration. The reactivity and porous property of hematite OC in CLC also increased during 10 redox cycle experiments. The CLC process accelerates the generation of CaH2P2O7 and CaHPO4 in cyanobacteria ash, which is more conducive to phosphorus recovery. Full article
