  • 摘要: 针对餐厨垃圾生物处理过程中产生的有机废物，为了实现餐厨垃圾的资源化利用，使用热重分析仪对其典型组分：塑料、骨头及难降解生物质，进行了单独及混合热重（TG）特性研究。结果表明：难降解生物质（BRB）、骨头等生物质类物质失重温度较低，最大失重率温度分别为325和341℃，塑料的失重温度较高，最大失重率温度在475℃；通过对混合物料的热重曲线和动力学分析，在较低温度（400℃）状态下，二者在热解过程中有协同作用；含有3种组分的实际物料在166~361℃条件下热解过程符合二维相界反应（函数为2（1-α）1/2）；而在361~550℃热解符合三级动力学反应（函数为（1-α）3），在整个温度阶段（166~550℃）中的实际活化能低于模拟活化能（59.69-1），表明3种物料混合热解有协同作用。
    Abstract: In order to enhance resource utilization of the organic solid residues obtained from food waste biological treatment, characterization of the organic solid waste was investigated. The typical components were plastics, bone and bio-refractory biomass. One separate component and one mixed components studies on thermo-gravimetric(TG) characteristics were conducted. By Thermo Gravimetric Analyzer (TGA), results showed that weight loss temperature of bio-refractory biomass and bone occurred at lower temperature. Maximum weight loss rate of temperatures were 325 and 341℃ respectively. Weight loss of plastic occurred at a higher temperature, maximum weight loss rate of temperature was 475℃. Through analyzing and comparing of experiment TG/DTG curve and simulation TG/DTG, it showed that at low temperatures (400℃), plastic and bone promoted the pyrolysis process. Mixture of the three components with pyrolysis temperature at 166~361℃ exhibited no synergistic reactions as demonstrated with 2-dimentional phase boundary reaction, (function 2(1-α)1/2). Pyrolysis of 361~550℃ subject to three levels of dynamic response, and thermal simulation of actual activation energy was less than the activation energy in the process (59.69-1). It showed that mixture of three components could promote the pyrolysis process.
