Quantitative Analysis of Pyrolysis Products of Wood Material I.: Pyrolysis of Japanese red pine wood meal by a tube-type kiln@@@アカマツ木粉の管状炉による熱分解
Japanese Red Pine (Pinus densiflora) wood meal was subjected to pyrolysis by the use of a tubetype kiln at 350 or 600°C. Pyrolysates were separated into pyrolysis residue, condensates (liquid phase pyrolysates) which included those obtained by cooling gas phase pyrolysates to -4°C, and the remainder (gas phase pyrolysates). The weight yield of condensates varied from 30 to 50%, and that of pyrolysis residue from 20 to 50% depending on the pyrolysis temperature. In the condensates, 18 identified compounds could be identified by GC-MS (Gas Chromatography-Mass Spectrometry), and each compound was determined by GC. Detailed evaluation was made for the pyrolysis conducted by raising the temperature to 600°C. The 18 identified compounds accounted for only about 10% of the condensates. Determination of water in the condensates by H-NMR suggested that 60% of the condensates was water and, thus, 40% was organic substances. Therefore, the 18 identified compounds accounted for 25% of the organic compounds in the condensates. Yield of each fraction was also evaluated based on the carbon content. Organic carbon in the pyrolysis residue and the condensates accounted for 60% and 20%, respectively, of the carbon originally present in the wood meal. Therefore, the remaining 20% was produced as gas. The carbon of the 18 identified compounds accounted for 8% of the carbon of the wood meal, and 40% of the condensate.
