Detailed description of production method
Feedstock was dried at 105 °C for 24 h and weighed prior to loading into a 1 L stainless steel retort. The retort, equipped with thermocouples placed at the center, bottom, side, and front, was then covered with a lid and placed into a furnace. The retort was purged for 1 h to create an inert atmosphere, and a constant flow of N2 was maintained at 2 L min−1 during pyrolysis. Slow pyrolysis was performed in a muffle furnace with a heating rate of 2.5 °C min−1. After the desired final temperature was achieved, heat supply from the furnace was stopped and the sample cooled slowly to room temperature.
Assurance provided for that the feedstock does not contain inorganic wastes (plastic, rubber,PCB, etc.), paints or solvents?
