Torrefaction performance prediction approached by torrefaction severity factor

Fuel, 2019
Abstract Torrefaction is a crucial biomass upgrading technology to produce biochar for fuel, soil amendment, and bio-absorbent. A number of indicators such as weight loss (WL), torrefaction severity index (TSI), and severity factor (SF) have been conducted to describe the torrefaction degree.

Torrefaction and co-torrefaction characterization of hemicellulose, cellulose and lignin as well as torrefaction of some basic constituents in biomass

Energy, 2011
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 ...

Poplar wood torrefaction: Kinetics, thermochemistry and implications [PDF]

open access: yesRenewable and Sustainable Energy Reviews, 2021
The kinetic and thermochemical models for poplar wood torrefaction were developed in the present work. The torrefaction kinetic model satisfactorily fitted the experimental thermogravimetric analysis (TGA) data of poplar wood torrefaction and provided a ...

Stump torrefaction for bioenergy application

open access: yesApplied Energy, 2013
A fixed bed reactor has been developed for study of biomass torrefaction, followed by thermogravimetric (TG) analyses. Norway spruce stump was used as feedstock.

The influence of torrefaction on pyrolysed biomass: The relationship of bio-oil composition with the torrefaction severity

Bioresource Technology, 2020
In this study, three types of biomass were torrefied at different times (0.5, 1, 1.5 h) and temperature (200, 240, 280, 320 °C), which were further pyrolyzed at 550 °C after torrefaction. CEI (carbon element index), which was established based on the carbon content of the torrefied biomass, was chosen as an indicator for reflecting torrefaction ...

Torrefaction of pomaces and nut shells

Bioresource Technology, 2015
Apple, 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 ...

Torrefaction of wheat-barley straw: Composition and toxicity of torrefaction condensates

Biomass and Bioenergy, 2019
Until now, few studies on the valorisation of torrefaction condensable volatiles (condensates) have been performed.
