The torrefaction of Loblolly pine (Pinus taeda) was examined at 250 and 300 °C, to determine the effects of treatment temperatures on the chemical structure of the torrefied Loblolly pine. Solid-state cross-polarization/magic angle spinning (CP/MAS) 13C nuclear magnetic resonance (NMR) spectroscopy was used to characterize the torrefied and native ...

Torrefaction of Hydrolytic Lignin
Solid Fuel Chemistry, 2018The torrefaction of hydrolytic lignin was studied at 0.1 MPa and 250–300°C. It was established that the process was accompanied by changes in the granulometric composition of the hydrolytic lignin. It was found that the larger the fraction of the test material and the higher the torrefaction temperature, the more changes in the granulometric ...

Plant Origin Biomass Torrefaction Process. Investigation of Exothermic Process during Torrefaction
2018The most promising technology of biofuel preliminary preparation for combustion is the low-temperature pyrolysis process (torrefaction). Torrefaction consists in raw material heating in an oxygen-free environment up to temperatures of 200-300 °C with subsequent holding.

Torrefaction of pomaces and nut shells
Bioresource Technology, 2015Apple, grape, olive, and tomato pomaces as well as almond and walnut shells were torrefied at different temperatures and times in a muffle furnace. The fiber content and thermal stability of the raw byproducts were examined and the moisture and ash contents, elemental composition, and gross calorific values of the raw and torrefied samples were ...

Biomass conversion through torrefaction
2013Torrefaction is a mild thermal pretreatment and refinement process presently attracting extensive interest and attention. Operating temperatures are between 200 and 350◦C and it quite closely resembles the process of roasting coffee beans. Thereby the word torrefaction, which is simply French for roasting. The resulting torrefied biomass (Fig.

Torrefaction is a thermal pretreatment process for biomass where raw biomass is heated in the temperatures of 200e300 C under an inert or nitrogen atmosphere. The main constituents contained in biomass include hemicellulose, cellulose and lignin; therefore, the thermal decomposition characteristics of these constituents play a crucial role in ...
