“…24,25 Like the moisture content, the volatile content of the biochar also decreases as the biomass degradation reaction progresses, i.e., as the pyrolysis residence time increases. 26 When the temperature is fixed and the residence time is varied, the heating rate, which depends on the temperature and time, leads to rapid volatilization so that the reactions occur in a short time, i.e., any small change in this variable leads to a large difference in the properties of the biochar, 27 which probably led to a difference in the volatile matter content between BIO240min and BIO60min.…”

In the present work, the effect of residence time on the production of biochar by the pyrolysis process of Pinus spp. was investigated. Biochar was produced at three different residence times in the reactor (30, 60, and 240 min). The effect of residence time on the load in the pyrolysis process was evaluated based on the rheometric, physical and mechanical properties of the elastomeric compounds. The shortest residence time, 30 min, produced a biochar with a graphitic structure (turbostratic) that was ideal for the interaction between load and elastomer and caused the least possible disturbance to the crystallization process by stretching the natural rubber, which was observed from the tensile strength, while maintaining the mechanical properties. As the residence time increased, it was observed that the more crystalline structure interfered with the crystallization process of the natural rubber when stretched, causing a decrease in tensile strength and decreasing the interaction between the load- elastomer, thus increasing the vulcanization time of the rubber. The compound was prepared using the filler with the longest residence time (NR/BIO240min).

“…15,16 It was found that the ash content enters equilibrium after a residence time of 60 min as carbonization is almost complete, which is also supported by the work of Wang et al 28 The fixed carbon content in biochar also increases with increasing residence time. 26,29…”
