TLDR
In this paper, the concept of a nozzle reactor with countercurrent mixing has been identified as suitable for upscaling of fast hydrothermal liquefaction (HTL) of solid biomass residues and wastes.Abstract:
The concept of nozzle reactor with countercurrent mixing has been identified as suitable for upscaling of fast hydrothermal liquefaction (HTL) of solid biomass residues and wastes. It is because of the fact that the reactor is capable of very fast heating and tolerating solid particles suspended in the liquid stream flowing through the reactor. A laboratory-scale setup has been developed, adopting the nozzle reactor concept. The reactor performance including the countercurrent mixing has been investigated and tested for fast HTL of lignin residues from steam explosion. This chapter presents and analyzes the development and the need of optimization of the reactor.read more

TL;DR: The current status of biomass gasification in near and supercritical water (SCWG) is reviewed in this article, where two approaches for SCWG are compared: low-temperature catalytic gasification, which employs reaction temperature ranging from 350 to 600 °C, and gasifies the feedstock with the aid of metal catalysts.

Hydrothermal conversion of biomass to fuels and energetic materials
TL;DR: The main research directions in the hydrothermal conversion of biomass into fuels and carbon throughout gasification to produce H2 or CH4, liquefaction to produce crude oils and phenols from lignin as well as carbonization to produce carbonaceous materials which can be either used as fuels (carbon negative chars) or interesting energetic materials (hydrothermal carbons).
