In this study, RDF was pelletized, co-pelletized with lignocellulosic biomass (1:1), and then used as a feedstock in CO2 gasification simulation tests using a TGA apparatus to verify its behavior and feasibility for syngas production. The RDF pellets had lower moisture content (5.42%) and better physical characteristics, such as durability (99.53%) and fines content (0.49%), suggesting that their physical integrity could be maintained during transportation and storage. Co-pelletizing improved the quality of the pellets, reducing the ash content and increasing the higher heating value. The gasification simulation tests showed that the RDF pellets with added biomass gasified more slowly and less linearly, whereas the RDF pellets converted faster and more uniformly.

摘要

In this study, RDF was pelletized, co-pelletized with lignocellulosic biomass (1:1), and then used as a feedstock in CO2 gasification simulation tests using a TGA apparatus to verify its behavior and feasibility for syngas production. The RDF pellets had lower moisture content (5.42%) and better physical characteristics, such as durability (99.53%) and fines content (0.49%), suggesting that their physical integrity could be maintained during transportation and storage. Co-pelletizing improved the quality of the pellets, reducing the ash content and increasing the higher heating value. The gasification simulation tests showed that the RDF pellets with added biomass gasified more slowly and less linearly, whereas the RDF pellets converted faster and more uniformly.
