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:

Etude découplée des phénomènes physicochimiques impliqués dans les réacteurs de gazéification de la biomasse. Application au cas d'un lit fluidisé double
TL;DR: In this article, le gazeifieur a lit fluidise double permet la production d'un gaz de synthese contenant du methane, and les processus intraparticulaires controlant la pyrolyse de la biomasse, ainsi que les reactions gaz/solide (vapogazeification du charbon et craquage thermique and catalytique des vapeurs sur olivine) sont etudiees de maniere decouplee, independamment les unes des autres

Effect of subcritical water treatment on the structure and foaming properties of egg white protein
TL;DR: In this article, the effect of heat treatment and subcritical water treatment on the structure and foaming properties of egg white protein (EWP) was investigated. And the results of SDS-PAGE electrophoresis revealed that SW treatment could induce the surface of EWP rougher, looser and more fragile.
