| 摘 要： | 以饮料厂副产物中药渣、单成分中药材及其蒸煮残渣作为研究对象,分析因蒸煮作用导致的燃料理化性质差异,通过热重、管式炉等实验手段以及气相色谱仪、气相色谱-质谱联用仪等测试手段研究中药渣的热解气液固产物特性。结果表明:相比于中药材,药渣的挥发分有所提高,Na、K、Mg、Cl、Si等元素含量降低;基本有机官能团变化不大;蒸煮后,药渣的最大失重速率提高且失重峰向高温区移动,热解残余率降低;相同温度下,热解气热值蒸煮前后(15.04~18.57 MJ/m^3)变化较小,但比麦秆热解气热值(10.63~16.23 MJ/m^3)高;蒸煮后,相同温度下药渣的热解液相产率较高(55.72%~61.92%),而焦油中苯酚的相对含量降低;相同温度下,蒸煮会降低药材的固体产率(27.62%~30.76%),但有利于增加药渣热解半焦比表面积,进而有利于热解半焦的气化反应。
