Resumen: This study explores the gasification of textile waste at 900 °C using different gasifying agents: air, CO2, and mixtures with steam. The research focuses on evaluating the composition and quality of the produced syngas, the characteristics of the generated tars, and the energy balance of the process for each gasifying agent.
The results indicate that air is the most efficient gasifying agent from an energy perspective, yielding a well-balanced syngas composition. However, the introduction of steam alongside air enhances syngas quality by increasing the H2/CO ratio, making it more suitable for energy and chemical applications. This improvement comes at the expense of higher tar production, which may require additional treatment. Conversely, CO2 as a gasifying agent maximizes gas yield and cold gas efficiency, showing potential for improved process performance.
Similar trends are observed when these results are compared with gasification studies of other waste materials, reinforcing the viability of textile waste as a feedstock for thermochemical conversion. These findings suggest that textile waste gasification could be a promising alternative for energy recovery, reducing environmental impact while contributing to circular economy strategies.
