“…The degradation of biomass into bio-oil, biochar, and syn-gas involve completely thermochemical conversion procedures, such as pyrolysis, liquefaction, gasification, torrefaction, and carbonization [17][18][19]. These thermochemical conversion yields are mainly affected by a poor determination of elemental contents (C, H, N, O, S) proximate (FC, VM, MC, Ash), and structural composition (cellulose, hemicellulose, lignin, and ether extractive) as reported by [20].…”
