Abstract: With the advancement of circular economies both domestically and internationally, coupled with the establishment of the “dual carbon” goals, the reuse of waste materials within the manufacturing sector has become a critical issue. Transmission breakage residue, as a typical industrial mixed plastic waste in manufacturing, poses urgent environmental pollution and resource wastage issues that require resolution during its processing. In this study, a gasification system is established using transmission breakage residue as the feedstock, and the effects of oxygen ratio, steam-to-carbon ratio, carbon-to-carbon ratio, and reforming temperature on the composition and yield of syngas are systematically analyzed. The results show that appropriate adjustment of process parameters can significantly increase the H2 and CO yields in the syngas and improve the overall gasification efficiency. This work provides theoretical guidance and data support for the resource utilization of transmission breakage residue and similar solid wastes.
