Pyrolysis of Tobacco Rob: Effect of Particle Size on Kinetic Study

During pyrolysis of tobacco rob (TR), the operating parameters such as the temperature, the heating rate, and residence time and particle size affect the process and result of the pyrolysis. Some of these parameters have been closely considered but the particle size of TR is often ignored. In this study, the size of TR particle was considered as a major factor in determining the mass loss in thermogravimetric analysis (TGA). The TGA results showed that the conversion rate increased and the activation energy decreased with a decrease in particle size. Minimizing the size of raw materials is an alternative method to improve the gas quality of TR pyrolysis.
