Mechanisms of liquefaction and pyrolysis reactions of biomass
TLDR
In the liquefaction process, the micellar-like broken down fragments produced by hydrolysis are degraded to smaller compounds by dehydration, dehydrogenation, deoxygenation and decarboxylation as mentioned in this paper.About:

High-strength charcoal briquette preparation from hydrothermal pretreated biomass wastes.
TL;DR: In this paper, the authors investigated the physical properties and combustion characteristics of the derived charcoal briquettes to assess the feasibility of its application as barbecue charcoal and found that the results indicated that the mass densities and compressive strengths of HT charcoal briques are better than those of DT and unpretreated charcoal briqueettes, even those of the commercial barbecue charcoal with binder addition.

Wood moisture content during the thermal modification process affects the improvement in hygroscopicity of Scots pine sapwood
TL;DR: In this article, the effect of elevated wood moisture content is based on the impact of water on chemical reactions which determine the cell wall matrix stiffness, and it was shown that the modification in oven-dry state increased the cellwall matrix stiffness which improved dimensional stability and hygroscopicity.

Effect of ash on hydrothermal liquefaction of high-ash content algal biomass
Wan Ting Chen,Wanyi Qian,Wanyi Qian,Yuanhui Zhang,Zachary Mazur,Chih Ting Kuo,Karalyn Scheppe,Lance Schideman,Brajendra K. Sharma +8 more
TL;DR: In this paper, mixed-culture algal biomass from wastewater systems (AW) was separated into two fractions (AW-418 and AW-385) and converted into biocrude oil via HTL at 300°C for a 60min reaction time.

Hydrothermal carbonization of maize straw for hydrochar production and its injection for blast furnace
Guangwei Wang,Jianliang Zhang,Jui-Yuan Lee,Xiaoming Mao,Lian Ye,Wanren Xu,Xiaojun Ning,Nan Zhang,Haipeng Teng,Chuan Wang +9 more
TL;DR: In this paper, the authors investigate the characterized hydrochar of maize straw prepared via the hydrothermal carbonization (HTC) process as a solid fuel for blast furnace injection and find that with the increase in HTC temperature and time, the yields, H/C and O/C values of hydrochar decreased, and the higher heating value increased.

Biomass Gasification Using Carbon Dioxide: Effect of Temperature, CO2/C Ratio, and the Study of Reactions Influencing the Process
TL;DR: In this paper, the effect of temperature and CO2/C ratios on the output syngas was investigated in a bench-scale atmospheric bubbling fluidized bed gasifier and compared with an oxygen gasification study from literature.
