光皮梾木(Cornus wisoniana)是一种优良的能源树种,适种面积广泛,其油脂成分主要包含油酸、亚油酸、棕榈酸、硬脂酸等。笔者以光皮梾木油为原料,采用等体积浸渍法自制Ni/ HZSM-5固体催化剂进行催化裂解制备生物烃基燃料。分别考察了反应时间、反应温度和催化剂用量等因素对催化裂解反应的影响,得出最佳单因素工艺参数为反应时间60 min,反应温度440 ℃,催化剂用量为2.0%(质量分数),在该反应条件下液体产物产率高达79.53%;在单因素试验基础上进行响应面试验条件优化,探讨了各因素之间交互作用对产品转化率的影响,结果表明,各因素的一次项对转化率影响呈现显著水平,其中反应温度对转化率影响最为显...

With the increase of the world’s population, the improvement of people’s living standards, and the development of science and technology, the demand for energy fuel has increased rapidly. The ability to supply energy is directly related to the security of the country and the survival of the nation. However, the reserves of traditional fossil energy sources such as petroleum are steadily decreasing. At the same time, as the exploitation of fossil energy sources, problems such as climate warming, sharp decline in forests, spread of acid rain an...
