Thermal Studies on the Combustion Process of Treated and Untreated Cellulose


The degradation of cellulose and cellulose samples impregnated with certain salts has been investigated by thermal analysis techniques. The behavior in air and in nitrogen is noted, for both the treated and untreated samples. A comparison is made between the samples using the αrs plot, which can be used as a tool to examine the solid state reactivities of the materials being compared. The method relies on the calculation of the mass loss data from the thermogravimetry unit being converted into α, the fraction decomposed. This indicated the reactivity of the treated samples to be greater than that for α-cellulose in nitrogen. In air, the sample treated with ammonium phosphate appeared less reactive than α-cellulose.
