An analytical system employing a pyrolyzer connected with GC and GC/MS was developed to study chemical composition of nascent volatiles generated from woody biomass primary pyrolysis. The pyrolyzer consisted of two parts; the first part is a drop tube reactor at which sample particles are rapidly pyrolyzed and the second part is a tubular reactor in which secondary gas phase reactions of the primary volatiles are taking place. To get information on the chemical composition of the primary pyrolysis products which is required for implementing numerical simulation of the gas phase reactions of biomass primary products with a detailed chemical kinetic model, the compositions of volatiles with minimized secondary reactions are analyzed with two types of GCs and a GC/MS which are directly connected with the pyrolyzer for Cedar sawdust at 650 - 800 ℃ and residence time at the tubular part of 0.3 s. More than 40 compounds from the smallest molecule hydrogen to the largest methyl-naphthalene could be identified and 69 - 78 wt% of the products could be quantitatively analyzed.
