木質バイオマスの炭化反応 : スギ辺材木酢液成分の生成量に及ぼす酢酸水溶液処理および炭化物添加の影響 Carbonization of Wood Biomass : Effect of Pretreatment with Acetic Acid and Addition of Charcoal on Yields of Carbonization Products and Constituents in Wood-Vinegar from Sugi Sapwood モクシツ バイオマス ノ タンカ ハンノウ : スギ ヘンザイ モクスエキ セイブン ノ セイセイリョウ ニ オヨボス サクサン スイヨウエキ ショリ オヨビ タンカブツ テンカ ノ エイキョウ 松井, 隆尚 マツイ, タカナオ Matsui, Takanao 松下, 洋一 マツシタ, ヨウイチ Matsushita, Yoh-ichi 10274771 菅本, 和寛 スガモト, カズヒロ Sugamoto, Kazuhiro 魯, 保旺 Lu, Baowang Sugi(Cryptomeria japonica D. Don) sapwood, Charcoal, Wood-Vinegar, Capillary gas chromatography, capillary GC, Carbonization Abstract Sugi sapwoods treated with aqueous acetic acid were carbonized at 400 ℃ for 1h under nitrogen gas to afford wood-vinegar, wood-tar and charcoal. Yield of the wood-vinegar was increased by treatment with aqueous acetic acid, and yields of the wood-tar and the charcoal were decreased. Eleven components in the wood-vinegar were determined by capillary gas chromatography (capillary GC). Amounts of 5-hydroxymethyl-2-furaldehyde and 2- furaldehyde in the wood-vinegar were increased after the acid treatment, but amounts of carboxylic acids, phenols, pyrocatechol, guaiacols, and maltol were almost constant. A mixture of sugi sapwood and charcoal as an additive was carbonized at 400 ℃ for 1h under nitrogen gas. Amounts of acetic acid and propionic acid in the wood-vinegar were increased with the increase in charcoal amount. On the other hand, amounts of furans, maltol, phenols, pyrocatechol and guaiacols were decreased. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2003-07 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/245 https://miyazaki-u.repo.nii.ac.jp/records/2398 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 32 73 77 https://miyazaki-u.repo.nii.ac.jp/record/2398.1/files/KJ00002425488.pdf application/pdf 373.5 kB 2020-06-21
