, 2008 苯酚液化是生物质液化的重要手段,农作物秸秆是一种不均一的原料,而完全液化将其看作是"单一"的原料,针对这一问题本研究采用选择性液化处理方式对小麦秸秆进行了苯酚液化,并对比了选择性液化与完全液化。结果表明:低温下适当的浓硫酸用量、较高的苯酚用量、适当的反应时间有利于保留纤维素而选择性液化半纤维素和木质素;与完全液化处理方式相比,选择性液化反应条件温和,保留了大量的纤维素,大大提高了原料利用价值。通过均匀试验和数据回归分析并实验验证得到选择性液化优化条件为 ...

, 2012 采用气相转移法合成了一系列杂原子磷铝分子筛MeAPO-11(Me为Cu、Fe、Zn、Mn),并利用X射线衍射(XRD)、扫描电子显微镜(SEM)、热重-差热分析(TG-DSC)、漫反射紫外-可见光谱(DR UV-Vis)和等离子发射光谱(ICP)对其进行了表征,同时考察了它们对苯酚羟基化反应的催化性能。结果表明,采用气相转移法合成的MeAPO-11分子筛具有较高的结晶度和稳定性,杂原子可以通过同晶取代Al进入分子筛骨架。CuAPO-11具有较高的苯酚羟基化反应催化活性;MnAPO ...
