Changes on wood powder morphology and flowability due to thermal pretreatment, [PDF]

, 2011
National audienceTorrefaction is a thermal pretreatment of lignocellulosic biomass before gasification. This mild form of pyrolysis, carried out at temperatures between 200 and 300 °C, changes the physical and chemical properties of the material.

Biomas torrefaction process

, 2017
Torrefaction is a thermal pretreatment technology. It is also defined as isothermal pyrolysis of biomass occurring in temperature ranges of 200ndash;300deg;C and performed at atmospheric pressure in the absence of oxygen. Common biomass reactions during torrefaction include devotilization, depolymerization and carbonization of hemicellulose, lignin and

Thermal decomposition of black locust and wheat straw under torrefaction [PDF]

, 2015
In this work the torrefaction of two typical Hungarian biomass materials, wheat straw and black locust wood was studied. Three different torrefaction temperatures were applied: 225, 250 and 300°C with one hour isothermal period.

Increase of calorific value of two important feedstocks by mild torrefaction [PDF]

, 2016
In the last decades efforts have been made to replace fossil fuels by more sustainable feedstocks for the production of energy. A way to increase the travelable distance of this feedstock is to increase its energy content.

Effects of Torrefaction on Hemicellulose Chemical Structure in Cell Walls of Japanese Cedar

BioResources
Torrefaction is a promising technique for improving the thermochemical characteristics, including calorific value and hydrophobicity, of wood pellets. These properties of torrefied pellets are attributed to the degradation of the cell wall polymers, such

Coupled effect of torrefaction and blending on chlorine removal [PDF]

, 2018
Thailand is an agriculture-based country. It produces large amounts of open burned agricultural residues. A strategy to use them as biofuel all year round is to enhance their fuel properties by coupling blending and thermochemical pretreatment.

Explosion and Flame Propagation Properties of Coarse Wood : Raw and Torrefied [PDF]

, 2016
A current production torrefaction process was used and the explosion and flame propagation properties were determined at the particle size of the raw (spruce, pine and fir – SPF) and torrefied biomass. The biomass material as received was sieved to
