Solar and biomass hybridization through hydrothermal carbonization

Hydrothermal carbonization process can transform wet bio-wastes into value-added products. This work aims to hybridize a concentrating solar technology and biomass reactor for the continuous sustainable valorization of biomass. The novel proposed integrates linear beam-down field with twin-screw HTC process. consists two reflections that concentrate linearly sun energy on ground, where is placed. A mathematical model solve both heat transfer kinetics co-rotating reactor. incoming flux from (8–20 kW/m2), length (L/D = 30–60 D diameter) rotating velocity screw (25–100 rpm) are main variables used up desired severity factor. simulation results different lignocellulosic biomasses (loblolly pine, sugarcane bagasse, corn stover rice husk) validated against literature data. developed shows good agreement experimental shown in literature. foresees hydrochar yields 64–78% factors 4.2 5.3, respectively, 63–70%
