Study on the Pyrolysis of Lignocellulosic Materials and Applications of Its Products as Bio-Fuels and Chemical Feedstocks (I)

為因應石化資源日漸枯竭及價格高昂之窘境，研究利用天然再生資源的木質材料作為能源和化學品的原料，以替代石油產品係世界各國努力的目標。本研究第三年係以尺寸為2×2×10 cm之國產柳杉及相思樹等木質材料為原料，在升溫速率100℃/hr、最高熱解溫度500℃及持溫1 hr之條件下製得木炭，再將木炭在升溫速度5 ℃/min、水蒸氣10 mL/min下，依不同木炭尺寸、活化溫度及持溫時間等變因，製得最佳性質之活性碳；在將350 mesh柳杉及相思樹活性炭與溶劑型及水性聚胺基甲酸酯(PU)展色劑，依不同體積濃度調配成不同活性碳塗料，並分析對甲醛吸附及電磁波遮蔽效果最佳之塗膜厚度。With declining reserves and fluctuating price of fossil fuels, the research for an alternative renewable lignocellulosic materials to replace petroleum has been intensified all over the world. Three years experiments will be conducted in this study. In this third year, the wood charcoals will be obtained from domestic lignocellulosic materials such as Cryptomeria japonica and Acacia confusa with dimension of 2×2×10 cm3 at heating rate of 100℃/hr, final temperature of 500℃ and holding time of 1 hr. The wood charcoals will be further activated at heating rate of 5℃/min and steam flow of 10mL/min to obtain the optimal performances of activated carbon according to the parameters such as the wood charcoal sizes, activated temperatures and holding times. In addition, the activated carbon coatings will be prepared by mixing a 350 mesh activated carbon with solvent and waterborne polyurethane vehicle with different volume concentrations as well as the adequate film thickness for the best efficiency of formaldehyde adsorption and electromagnetic wave shielding will also be examined
