An Extensive Review and Comparison of Modern Biomass Reactors Torrefaction vs. Biomass Pyrolizers—Part 2

Energies, 2023
The depletion of fossil fuels has led to a search for new methods of fuel and chemical production from biomass. One of the methods of converting biomass into valuable products is the process of pyrolysis.

Physicochemical characteristics of biomass‐coal blend char: The role of co‐pyrolysis synergy

Energy Science & Engineering, 2021
Co‐pyrolysis synergy between cornstalk and bituminous coal was investigated based on the physicochemical properties of the char. The char was prepared by directly putting the individual or blended materials into a heated resistance furnace at 600°C or ...

Gasification of woodchip particles: Experimental and numerical study of char–H2O, char–CO2, and char–O2 reactions [PDF]

Chemical Engineering Science, 2011
In wood gasification, oxidation of char particles by H2O, CO2 or O2 plays a major role in the performance and efficiency of air gasifiers. These reactions are generally analyzed under carefully design and controlled laboratory conditions, using either micro-samples to focus on the reaction kinetics or large spherical particles, but rarely using the ...

Use of Biochar-Producing Gasifier Cookstove Improves Energy Use Efficiency and Indoor Air Quality in Rural Households

Energies, 2019
Biomass fuels dominate the household energy mix in sub-Saharan Africa. Much of it is used inefficiently in poorly ventilated kitchens resulting in indoor air pollution and consumption of large amounts of wood fuel.

Variation of Char Structure during Anthracite Pyrolysis Catalyzed by Fe2O3 and Its Influence on Char Combustion Reactivity

, 2009
Effects of Fe2O3 on the pyrolysis reactivity of demineralized anthracite were investigated by a thermogravimetric analyzer, indicating that pyrolysis reactivity of Fe2O3 loaded demineralized anthracite was higher than that of raw demineralized anthracite

Chars [PDF]

Encyclopédie berbère, 1993
Avant d’etre cavaliers, les ancetres des Berberes furent de non moins celebres conducteurs de chars. Pour cette periode fort ancienne, rares sont les allusions litteraires mais elles sont precises et bien documentees. La premiere et la principale mention concerne les Libyens orientaux : nous savons grâce aux bulletins de victoire de Ramses III que les ...
