TITTLE:  Kinetics and Thermochemistry of Biomass Torrefaction

ABSTRACT: 

The direct use of lignocellulosic biomass (e.g., agricultural and forest residues) as fuel is inefficient because of its poor energy efficiency (e.g., low heating value, high moisture content, hygroscopic nature, low density and polymorphism, and high during transportation, handling and storage costs). Besides improving physicochemical properties of biomass, torrefaction can also improve its thermal conversional performance. The kinetics of biomass torrefaction is fundamental for the prediction of thermal decomposition kinetic characteristics under different torrefaction conditions and is helpful for the design, scale-up, optimization and industrial application of torrefaction processes/systems. The kinetic and thermochemical models for woody biomass torrefaction will be presented and discussed.
