| 英文摘要 | The contents of ash and chlorine, and the heating value are important factors for the utilization of biomass. In this work, the washing of corn straw with water for de-ash, de-chlorination, and increase of the heating value was investigated. Before washing, the corn straw was ground to powders and fractionated into different particle sizes. The particles less than 38 mu m were found in higher content of chlorine, and thus were removed and only the powders in the range of 38-250 mu m were examined. Three independent variables of the liquid/solid ratio (L/S), the washing time (t), and the washing temperature (T) were investigated in the washing experiments. A mathematical model was constructed by response surface methodology (RSM). The results showed that the parameter of L/S was most significant, followed by the order of t, the interaction between L/S and t, and T. The reliability of the model was verified by analysis of variance and by comparison with laboratory results. According to the model prediction, the optimal conditions of L/S, washing time, and temperature were respectively determined as 39.98 mL/g, 11.55 min, and 30 degrees C. The details of the washing influence were further investigated, by characterizations of the eluate and the solid samples before and after washing. |
