Controlled hydrothermal carbonization of wood-derived lignin-rich lignocellulose: Redefining pyrolytic pathways to tailored biochar and hydrogen-enriched syngas

This research illustrates the efficacy of hydrothermal carbonization (HTC) as a pretreatment method to improve the pyrolytic performance of wood-derived lignin-rich lignocellulosic biomass (LB), supported by thorough characterization of its derived products such as syngas, tar, and biochar. A systematic comparison of non-HTC-treated LB and HTC-treated LB through their respective pyrolytic-derived biochar (NLB, HLB) obtained…

Reductant atmospheres during slow pyrolysis of cellulose: First approach to obtaining efficient char -based catalysts in one pot

Char based metallic (Pd-Au-Ru-Pt/C) catalysts have drawn increasing research interest due to their versatility in biomass related industrial reactions. Recent studies dealing with the synthesis of char-based catalysts in one single step (one-pot) use reductant atmospheres for biomass pyrolysis. In this work, the influence of the use of a reductant N2/H2 atmosphere on the physicochemical…
