| 目的 为了提高沙柳木粉的液化率， 应用响应面法对沙柳木粉液化工艺进行优化。方法 单因素试验对沙柳木粉液化工艺进行初步优化， 在此基础上， 通过响应面法优化， 得到试验因素之间的定量数学模型及单因素和因素间交互作用对沙柳木粉液化率的影响。结果 液化剂和木粉质量的比值 （液固比）、 反应温度、 反应时间和催化剂的质量分数对沙柳木粉液化率有显著影响。沙柳木粉液化的最优工艺为液固比4， 反应时间140 min， 反应温度170 ℃， 催化剂质量分数5%， 在此条件下， 沙柳木粉液化率为97.84%， 与模型预测值接近。结论 响应面法优化得到的液化工艺参数可靠。 |

| In order to improve the liquefaction yield of Salix flour, the liquefaction process of Salix flour was optimized by response surface methodology (RMS). The mono-factorial experiment was used to preliminarily optimize the liquefaction process, and on this basis, response surface methodology was used for further optimization, obtaining the quantitative mathematical relation model between the test factors and the effects of single factors as well as the inter-factor interactions on the liquefaction rate of Salix flour. It was shown that the significant external factors affecting yield of Salix flour were liquid-solid ratio, reaction temperature, reaction time and catalyst content. The optimized Salix flour liquefaction process was: liquid-solid ratio 3.68, time 143.83 min, temperature 172.18 ℃ , catalyst content 5% , and the Salix flour liquefaction yield under this condition was 97.84% , which was close to the model predicted value. In conclusion, the liquefaction process parameters obtained by response surface methodology were reliable. |
