Torrefaction of wood and its constituents: Experiments and modelling of co-products for green chemistry application

摘要

How to model torrefaction vs T, residence time and biomass composition ? 1. Sum of the main biomass constituents: 1.1 Correct when T ≤ 250℃C 1.2 Interactions between cellulose and other compounds when T ≥ 280℃ Empirical factor on cellulose decomposition rate 2. Satisfactory prediction of: 2.1 Solid mass loss 2.2 The 8 main volatile species yields: H_2O, formaldehyde, acetic acid, CO_2, CO, formic acid, methanol, furfural Not produced by all constituents.
