Pyrolysis is a wellestablished thermochemical process that involves the thermal breakdown of biomass into various fuel components such as biochar, biooil and pyrolysis gas (A. V. Bridgwater, 2011). Biochar is a carbonaceous solid fuel which is considered an economical substitute for coal (Budarin et al., 2013; Cheng et al., 2020; Sakhiya et ...
