废塑料制取液体燃料试验研究

利用热解法将废塑料制成高品质液体燃料是资源回收和避免二次污染的重要途径。为此,设计了一套连续给料的鼓泡流化床反应器,对废塑料在鼓泡流化床中热解的关键工艺参数进行了试验研究。通过对试验数据的分析,得到了热解温度对液体产率的影响规律、气体产物的主要成分及其所占份额,并计算了废塑料热解过程的能量收支关系,为废塑料制取液体燃料的工业装置的设计、运行提供了理论及试验依据。

Study on experiment of waste plastic pyrolysis for producing liquid fuel

Using waste plastic to obtain high quality liquid fuel is an important approach which can recollect resources and avoid secondary pollution.Therefore,a bubbling fluidized bed with a continuity feeder was designed.The key technical parameters of waste plastic pyrolysis in the bubbling fluidized bed were investigated. The law of the effect of pyrolysis temperature on liquid generation rate and the main components and their percentages of gas products were attained according to experiment data analysis.Energy consumption and acquisition were also calculated,which provides the theoretical and experimental basis for designing and operating the industry devices of waste plastic producing liquid fuel.
