Thermochemical biofuel production in hydrothermal media: A review of sub- and supercritical water technologies
Andrew A. Peterson,Andrew A. Peterson,Frédéric Vogel,Russell P. Lachance,Morgan Fröling,Michael Jerry Antal,Jefferson W. Tester +6 more
TL;DR: Several biomass hydrothermal conversion processes are in development or demonstration as mentioned in this paper, which are generally lower temperature (200-400 °C) reactions which produce liquid products, often called bio-oil or bio-crude.

Journal ArticleDOI
A kinetic model for pyrolysis of cellulose.
TL;DR: In this article, it was shown that the pyrolysis of cellulose at low pressure (1.5 Torr) can be described by a three reaction model, where an initialization reaction leads to formation of an active cellulose which subsequently decomposes by two competitive first-order reactions, one yielding volatiles and the other char and a gaseous fraction.

Thermogravimetric and differential thermal analysis of cellulose, hemicellulose, and lignin
TL;DR: In this article, the authors investigated the thermal degradation of cellulose, hemicellulose, and lignin using the techniques of thermogravimetric analysis (TGA) and differential thermal analysis (DTA) between room temperature and 600°C.
Journal ArticleDOI
Competitive Reactions in the Thermal Decomposition of Cellulose
TL;DR: In this paper, it was shown that when cellulose is heated it undergoes two competitive reactions and the actual sequence of these is clarified, being different from that previously postulate.
Journal ArticleDOI
Effects of reactor severity on the gas-phase pyrolysis of cellulose- and kraft lignin-derived volatile matter
TL;DR: In this paper, the dependence of gas yields on temperature and residence time was explained by a global mechanism composed of two competing reactions: the first creates permanent gases by cracking the volatile matter, whereas the second creates refractory condensable materials.

Effects of pressure on biomass pyrolysis. I. Cellulose pyrolysis products
TL;DR: In this article, a three phase research program, using a tubular, laminar flow, micro reactor system, was undertaken to study the effects of pressure on biomass pyrolysis.
