On-Line Analysis of the Condensable Products of Biomass High Temperature Pyrolysis

Abstract:

High temperature pyrolysis of sawdust was achieved by using the analytical Py-GC/MS technique which allowed the on-line analysis of the pyrolysis product.The experiments at the different temperatures (700-1000°C) and the different mass ratios of CaO to sawdust (0%,10%,30%,50%) were carried out,respectively. At different temperatures, the distribution of condensable products considerably changed. At 700°C,the aromatic hydrocarbon yield were 0.9% of the total peak area. However, the aromatic hydrocarbon yield reached 59.4% of the total peak area at 1000°C, which might be due to the occurrence of the condensation polymerization at high temperature. CaO had a positive effect on decreasing the yield of the condensable products of sawdust pyrolysis, but did not remarkably change the distribution of the condensable products.
