To turn biomass into energy products (bio-oil, stable biochar, and pyrolytic gas), employed pyrolysis as a dynamic thermochemical method carried between 400 °C and 700 °C [85]. The properties of pyrolysis products are significantly evaluated by temperature, whereas the heating rate specifies the type of biomass pyrolysis that is either fast or slow. In the absence of O₂, slow pyrolysis carried out at an extended period and optimized temperature results in maximum biochar yield compared to rapid pyrolysis [86]. Biochar can be used in boilers, as a catalyst, as an adsorbent, and in other manufacturing processes as solid fuel. For internal combustion engines and other techniques, pyrolytic gas may be a sustainable alternative fuel [85, 86]. Currently, the Life Cycle Assessment (LCA) approach evaluates the environmental effects of fuel combustion, electricity production, eutrophication, and N fertilizer synthesis from agricultural biomass in Shandong’s northern area in China [87]. They claimed in the study that the distributed-centralized agricultural straw pyrolysis (DCP) system was both socially and economically more advantageous for managing the disposal of crop residues compared to the traditional straw incorporation biprocess.
