Special Issue Information

Dear Colleagues,

Gasification, one of the major thermochemical conversion methods, is becoming a promising technology for biomass utilization with a positive environmental impact. Its versatile role in contributing to the demand for heat, electricity and syngas has qualified it as a decentralized energy conversion option. Its significant advantages in terms of renewability, carbon neutrality and high efficiency render this technology highly popular in countries with strong support for renewables and unused biomass. The use of the catalytic approach to improve the biomass gasification process has been widely researched in academia and applied in industry, ranging from feedstock pretreatment, gas–solid–liquid product distribution, in situ and ex situ tar abatement, gas composition regulation and downstream upgrading.     

This Special Issue on “Catalytic Improvement of Biomass Gasification Process” welcomes submissions on novel catalytic findings related to the biomass gasification process. Research methods including process modeling, experimental studies, theoretical calculations or their combinations are accepted. Topics include, but are not limited, to the following areas concerning biomass gasification:

  1. Catalytic pretreatment of feedstock;
  2. Intensification of the catalytic process;
  3. Catalytic adjustment of products;
  4. Catalytic removal of tar;
  5. Catalytic upgrading and conversion of gas;
  6. Catalytic utilization of char.

In this study, red mud oxygen carriers were obtained by varying the preparation temperature and characterized using XRD, SEM, BET, and H2-TPR. The results showed that the oxygen carrier prepared at 1000 °C exhibited high reactivity due to clear grain boundaries, uniform size, high porosity, and smooth grain morphology. Additionally, the release of oxygen was accelerated, as indicated by the H2-TPR results. The water hyacinth, an aquatic plant of agroforestry waste, was selected as the research object, and the chemical looping gasification (CLG) reaction performance with prepared red mud carriers was investigated. The experiment results showed that the total gas yield (Yg) of the carriers prepared at 1000 °C reached a maximum of 1.02 Nm3/kg, had a high low-level heating value (LHV) of 12.06 MJ/Nm3, cold gas efficiency (CGE) of 91.49%, and carbon conversion rate (ηc) of 82.65%. This indicated that the red mud carriers synthesized at 1000 °C have a faster oxygen release rate, more concentrated oxygen release, and stronger reaction activity. Full article
