摘要
以动态搅拌装置催化裂解轮胎胶粉实验平台,研究了温度(450~700℃)对轮胎胶粉热解产物分布的影响;并且对比了多种催化剂,包括:NaOH、CaO、Fe粉、Fe_2O_3、C粉以及高炉渣,对轮胎胶粉裂解产物分布的影响。目的是寻找到适合轮胎胶粉裂解的催化剂与使用含量。结果表明,裂解油产率随着裂解炉温度的升高先增加后减小,当试验温度为550℃时,裂解油产率最高。在最佳试验温度550℃时,对比了多种催化剂对各裂解产物组分分布的影响。得出结论:550℃,35%的NaOH含量得到最高裂解油产率。550℃,45%的Fe粉含量,对固体产物分布影响最大。550℃,高炉渣所占比重为35%时,得到的气体产物最多。
With catalytic pyrolysis tire rubber powder dynamic mixing plant of experimental platform,temperature( 450 ~ 700 ℃) was studied to the influence of tire rubber powder pyrolysis product distribution,And compared the various catalysts,including: NaOH,CaO,Fe powder,Fe_2O_3,C powder and BF slag,the impact on the tire rubber powder pyrolysis product distribution. The catalyst and use content for tire cracking are found. The results show that in order to achieve a high pyrolysis oil yield,moderate temperature are required. At temperature of 550℃,the maximum pyrolysis oil production yield reached 58%. At the best test temperature 550 ℃,compared the various effects of catalysts on the pyrolysis product composition distribution. Conclusion: 550 ℃,35% of the NaOH content was the highest pyrolysis oil yield. 550 ℃,45% Fe powder content,the greatest impact on the distribution of solid products. 550 ℃,the proportion of blast furnace slag was 35%,the highest gas product was obtained.
