Carbon-Dioxide-Assisted Gasification of Sunflower Husk: An Impact of Iron, Nickel, or Cobalt Addition

| Summary: | While the attempts to find new energy sources have intensified, the interest in the use of biomass as a carbon-rich raw material still is increasing. In this work, we studied iron-, cobalt-, and nickel-based materials in the process of CO<sub>2</sub>-assisted gasification of sunflower husk. The materials with and without metal additives were examined by XRD, SEM, EDX, and TEM techniques and were tested in their gasification under the action of CO<sub>2</sub>. It was found that the Co-based material demonstrates the best activity among the studied ones (the CO<sub>2</sub> conversion was up to 83%). The possible reason for such superiority may be related to the capability of Ni compounds to the formation of the metallic nickel phase and insufficient activity of iron species. |
