摘要

A seasoned sawdust of Douglas Fir wood was flash pyrolyzed in an entrained tubular reactor in the presence of hydrogen and helium at short residence times (less than 4 sec) at temperatures varying from 600 exp 0 to 1000 exp 0 C and pressures of 50 to 500 psi. A significant quantity of gaseous and liquid hydrocarbons and CO were produced. The liquid products were characterized via GC/MS and Pyrolysis Mass Spectrometry. The composition of the liquid products and the influence of the processing conditions on the product yields are discussed. 2 references, 13 figures, 2 tables. (ERA citation 09:030442)
