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:

Non-Isothermal Combustion Properties of Plant Biomaterial Using TG-DSC Technique
Li Xu,Yong Jiang,Rong Qiu,Wei Li +3 more
TL;DR: In this article, the authors investigated the combustion behavior of a typical plant biomaterial, corn cob, using TG-DSC technique and found that the process can be divided into three stages: dehydration, pyrolysis, and combustion.

Chemical-Free Extraction and Identification of Sugar Components from Oil Palm Biomass Through a Hydrothermal Process
Vasagi Ramachandran,Noor Shartika Jusoh,Megat Johari Megat Mohd Noor,Fazrena Nadia Md Akhir,Nor’azizi Othman,Zuriati Zakaria,Hirofumi Hara +6 more
TL;DR: In this article, the authors extract sugar-based products from oil palm biomass, oil palm fronds (OPFs) and oil palm fruit pressed fibers (FPFs) via a hydrothermal process using accelerated solvent extraction and to identify the sugar content of the aqueous phase at different temperatures and reaction times.

Application of hydrothermal processes to biomass and organic wastewaters to produce sustainable energy
J.R. Portela,Belén García-Jarana,J. Sánchez-Oneto,Nadjiba Benmakhlouf,Nawel Outili,Abdeslam Hassen Meniai +5 more
TL;DR: Two main hydrothermal processes are dealt with in this article, namely, Hydrothermal liquefaction, a combination of thermal depolymerization and a recombination process under moderate temperature ( 374°C and 220 bar), which is a highly exothermal process that releases a huge amount of heat and generates clean effluents.

Effect of formation behavior of hydrocarbons and solid component from cellulose on catalytic transfer hydrogenation in straight-chain aliphatic hydrocarbon solvent
TL;DR: In this paper, a straight-chain aliphatic hydrocarbon as a hydrogen source and solvent was used for converting cellulose to liquid fuel, and the results indicated that the cellulose-derived oxygenates absorb on cellulose surface and form a solid component.
