| 摘 要： | 以5W／％稀HCl溶液对各类城市生活垃圾衍生燃料（RDF）及其组分进行处理，考察在不同温度下快速热解生成半焦的动力学参数变化，并对半焦的比表面积和孔体积的变化和分形维数进行分析研究，试验结果发现酸洗后RDF热解速率提高，活化能降低，酸洗后半焦的比表面积和孔体积均有所减少，并随热解温度先升高而后下降，在450度附近出现极大值，对半焦的分形维数分析表明，酸洗后表面变得光滑，形成欧氏平面。

| Abstract: | Refuse derived fuel (RDF) and its components were treated by 5% HC1 and the changes of kinetic parameters for rapid pyrolysis under different temperature were discussed. The changes of the specific surface area (SSA), pore volume (PV) and fractal dimension for residue were also investigated and analyzed in this paper. The experiment results show that the pyrolysis rate increases and activate energy decreases for RDF after acid treatment. SSA and PV of RDF vary with the reaction temperature during rapid pyrolysis. With increasing temperature, the SSA and PV of acid treated RDF residue rise in the beginning and down in the end. The maximum value appears near 450℃. Further more, the fractal feature of acid treated RDF residue is also discussed. The surface of residue seems smoother and form Euclidean plane after acid treatment. |
