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.
