摘　　要： 以聚丙烯为试验物料,利用N2热等离子体在等离子体反应器内进行了一系列热解试验,重点考察了气体产物成分及含量。在反应过程中加入过热水蒸气以改善气体品质,在本实验条件下,气体产物中CO与H2之和可以达到40%,C2H2可达到5%。 Plasma pyrolysis of polypropylene has been tested for the propose of converting waste plastic into gaseous fuel and useful chemicals The plasma reactor has a DC arc nitrogen plasma generator with maximum input electric power of 55?kW and a reaction chamber of 50?mm inner diameter and 1?000?mm height The results of a series of experiments show that under our optimum experimental conditions of power input 352?kW, feed rate 60?g/min, the concentration of H2 and C2H2 at the exit of the chamber can be as high as 18% and 5% respectively The steam injection is introduced for improving the gaseous product quality With water steam injection, the sum of H2, CO in the gas products can reach to 40% while the decrease of C2H2 concentration is slight Meanwhile 96% of solid conversion and gas productivity of 2?160?mL/g are achieved The results indicate that plasma assisted thermal decomposition of polypropylene may be a useful way for recovering energy and useful chemicals from waste plastic
