中文摘要 | 在本文中,依據廢輪胎胎面橡膠熱裂解特性,配合文獻的實驗數據,建立廢輪胎熱裂解過程中,重量消失率對溫度的關係模式。再利用數值計算方法探討熱裂解反應速率與溫度之關係,配合裂解生成氣體組成的生成率,經由實驗數據與理論模式的比對以達到熱裂解生成產物的最佳模式如此可確認實驗的準確性與理論模式的正確性,進而可提供廢輪胎熱裂解處理廠,建立有用的熱裂解處理技術與操作。進一步可深入探討在不同操作條件下與改變控制參數,例如升溫速率、系統壓力、不同廠牌的輪胎胎面橡膠、觸媒,其對廢輪胎熱裂解的影響。且可探討將本研究的理論分析,運用於裂解其他物質的可行性。未來可運用本研究模式進行修正,以求得更精確的廢輪胎熱裂解模式,且在各種生成氣體量測難易度與成本考量,選擇成本較低之方式,以達到易量測且易控制參數變化,進而達成熱裂解生成產物的最佳處理模式。 |
英文摘要 | Waste tires are generated everyday since automobiles are necessities for daily life. As the resource is limited, recycling waste tires and turning them back into new resources is considered to be the most environmental friendly option. In order to develop the technique that waste tire recycling plants needs, the pyrolysis characteristic of waste tire was studied to understand the relationship between pyrolysis-derived gases and the temperature. Based on the pyrolysis characteristic of the waste tire tread and the published experimental data [1] [2], the model of relationship between the weight loss and temperature during the process of waste tire pyrolysis was set up in this paper. Then, a mathematical method was used to study the relation between the pyrolysis velocity and temperature, coordinating with gas generation rate during pyrolysis, to provide the practical techniques for the waste tires pyrolysis disposal plants. The mathematic model of tire pyrolysis established in this paper tried to simulate the temperature being heated up constantly from 300℃ to 600℃, with 50℃ increment as a section to detect the derived gases relatively. Based on the desired gas equation, mass constant equation and the generation rates of gases in different temperature sections, the effect of temperature on the generation velocity rate of the derived gases was obtained. Then, a model that could analyze the reaction velocity, temperature and time of waste tire tread pyrolysis was set up to control the velocity and time of pyrolysis. |
