【摘要】：本文提出了一維結(jié)渣動力學模型,并用該模型研究鋁電解槽廢舊陰極炭塊的高溫燃燒動力學。研究了不同碳含量和溫度對反應(yīng)速率的影響,實驗結(jié)果表明:在碳含量為70%~100%時,碳濃度變化對反應(yīng)速率的影響符合0.46級反應(yīng);在溫度區(qū)間為900~1080℃時,碳含量為72%的廢舊陰極炭塊活化能為2263.15k J/mol。動力學機理函數(shù)公式為1/αln|1-α|-1/α|1-α-αm|=βt
[Abstract]:In this paper, a one-dimensional slagging kinetic model is proposed and used to study the high-temperature combustion kinetics of waste cathode carbon block in aluminum reduction cell. The effects of different carbon content and temperature on the reaction rate were studied. The experimental results showed that when the carbon content was 70 ~ 100, the effect of carbon concentration on the reaction rate was 0.46, and at 900 ~ 1080 鈩，
