The formation and structure of chars produced on heating of cellulose, lignin, and wood have been investigated by FTIR and CP/MAS 13C-NMR, and the results have been discussed in conjunction with parallel permanganate oxidation studies reported before. These data show that when cellulose is heated fo

โฆ Synopsis
The EPR spectra of charred cellulose in the heat treatment (HTT) range from 50ยฐC to 600ยฐC were investigated. All samples above HTT 100ยฐC show a single absorption line. The line parameters such as g-factor, intensity, line width and the line shape strongly depend on the carbonization temperature. Thii dependence is discussed in relation to the i.r.spectra of the charred cellulose. _

Investigation of a series of chars prepared by rapid pyrolysis of cellulose in the temperature range of 400~800ยฐC has shown that they have a high chemisorptive affinity for oxygen. Maximum chemisorption occured on chars prepared at a HTT of 550ยฐC. The Elovich equation was used to describe the kineti
Cellulosic chars prepared at HTTs ranging up to 500ยฐC contain aromatic structures as evidenced by the production of benzene polycarboxylic acid derivatives on permanganate oxidation. Analysis of these products indicates the concentration of the aromatic units and the degree of substitution of benzen
An experimental and modeling study of cellulosic char combustion under laminar gas flow conditions was conducted covering the temperature range of 473-1173 K with 0.03-0.21 oxygen mole fraction in the feed gas. A gas film mass-transport limited model accurately fits the combustion rates measured in
In view of the significance of the properties and reactions of chars during the process of smoldering combustion, a series of cellulosic chars was prepared at temperatures ranging from 340 to 600ยฐC and their pyrolysis and combustion properties were studied by thermal analysis.
