Life-cycle assessment of pyrolysis processes for
To obtain higher quality biochar, grinding pretreatment of feedstocks may be required, especially for fluidized bed reactors. It is also noted that torrefaction pretreatment is often applied to improve the bio-oil quality in subsequent pyrolysis (Cen et al., 2021). Pyrolysis conditions and techniques are the critical factors for biochar production.
