Abstract
DSC and TG were used to study the effects of fire retardants on the pyrolysis of Pinus halepensis pine-needles and their components (cellulose, lignin and extractives). (NH 4) 2HPO 4 and (NH 4) 2SO 4 were used as fire retardants at the 10% w/w concentration level. The TG results showed that the mass loss profile of pine-needles resembles those of lignin and extractives. The DSC curves showed that in the presence of fire retardants there is a shift to lower pyrolysis temperatures for cellulose. In addition, there is an increase in the pyrolysis residue for both cellulose and pine-needles. Minor or negligible effects were observed for lignin and extractives in the presence of the retardants.
