      摘要:
      針對目前生物柴油的燃燒和熱解動力學分析不夠完善,本文采用熱重分析儀-傅里葉紅外變換光譜儀聯用對生物柴油分別進行氮氣和空氣氣氛下不同升溫速率的實驗,并分析所得到的熱重-熱失重速率(TG-DTG)曲線與紅外光譜圖。利用Kissinger法和Starink法分別計算出生物柴油在不同氣氛下的活化能與指前因子。以無模式函數法所求解的動力學參數作為初值,通過多元非線性回歸法求出相符的機理函數365英超体育投注,并進行F-檢驗以驗證其回歸良好。結果表明:生物柴油熱解和燃燒熱重-熱失重速率的曲線變化規律一致,皆隨升溫速率的提高而向高溫區移動365英超体育投注,且最大失重速率點接近;熱解和燃燒過程中氣態產物基本一致,僅在燃燒過程中在2 250~2 000 cm-1處檢測到一氧化碳的特征峰;多元非線性回歸法分析得出生物柴油熱解過程為單步動力學反應,燃燒過程為兩步連續動力學反應365英超体育投注。實驗分析和回歸求出的機理函數,可用于生物柴油燃燒和熱解過程的化學反應動力學特性預測。
