摘要
高温裂解技术是化学工程与工艺专业学生应该掌握的一种重要的化工技术。本文研究了通过高温裂解松木层孔菌制备松木层孔菌基生物炭和生物油的实验。松木层孔菌基生物炭经扫描电镜分析和红外光谱分析,确认是一种多孔材料,在模拟印染废水处理中具有较好吸附脱色作用。而松木层孔菌基生物油经气相色谱–质谱联用分析,主要是一些易燃低沸点和高沸点小分子化合物的混合物。在此基础上设计了以废弃生物质为原料制备生物炭和生物油的实验教学方案。将该实验教学方案应用于佛山科学技术学院2016~2018级化学工程与工艺专业学生的《生物质化工技术实验》课程实验教学,取得了较好的实验教学效果。
Pyrolysis technology is an important chemical technology that students majoring in chemical en-gineering and technology should master. The experiment of biochar and bio-oil prepared by pyroly-sis was studied in this paper. Through scanning electron microscopy and infrared spectroscopy, it was confirmed that the Phellinus pini-based biochar is a porous material that has a good adsorption and decolorization effect in the treatment of simulated printing and dyeing wastewater. And according to the results of gas chromatography-mass spectroscopy, the bio-oil is mainly a mixture of some flammable low-boiling and high-boiling point small molecular compounds. Based on this, the experimental teaching scheme of biochar and bio-oil from waste biomass is designed and applied to the experimental teaching of the curriculum “Biomass Chemical Technology Experimental” of 2016~2018 grade students majoring in chemical engineering and technology of Foshan University, and achieved good experimental teaching results.
