Abstract:
The slow pyrolysis of cellulose, xylan, lignin and resinous pellets was studied using differential scanning calorimetry (DSC), thermogravimetry (TGA), and evolved gases analysis using FTIR spectrometry. A high heating rate, a low sample mass and the use of a higher grain size fraction decreased the charcoal yield of the resinous samples pyrolysis. Carbon dioxide, carbon monoxide, furfural and formaldehyde were found to be released during cellulose pyrolysis. Carbon dioxide production of xylan and cellulose were found to occur during the thermal event observed by DSC, when no specific thermal event could be related to CO2 production of lignin. The cellulose content of the resinous pellets could be observed both on DSC and CO2 production traces, when its lignin content could clearly be identified only on the DSC trace.
