Pyrolysis of plastic wastes is a promising method to produce value-added liquid transportation fuels, as it also reduces the accumulation of plastic wastes and prevents them from landfilling. In this study, waste plastic gasoline (WPG) produced by atmospheric distillation of pyrolysis oils was characterized and compared to the transportation fuel standards. Low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP), and polystyrene (PS) were blended with mass ratios representing the plastic demands in Hungary, EU, and the world, as these mixtures are promising candidates for the formation of gasoline-like fuels by pyrolysis. Typically, a 473–512 g/kgwaste WPG yield was produced, and the fuels were tested in a traditional spark-ignition engine without any modifications or fuel blending. The olefin content and the distillation properties of the WPG were out of the EN228 limits, but the rest of the investigated parameters fulfilled the requirements. Based on the engine tests, a slight decrease in gasoline fuel consumption was noticed compared to commercial gasoline (RON = 95); however, a slight increase in NOx was also demonstrated. Results indicate that the initial solid waste blend dictates the composition of the WPG, and the concentrations of the different components can be affected by the recipe of the materials used.

从废塑料混合物中蒸馏热解油得到的汽油样运输燃料的特性

塑料废物的热解是生产增值液体运输燃料的一种有前途的方法,因为它还减少了塑料废物的积累并防止它们被填埋。在这项研究中,对通过热解油的常压蒸馏产生的废塑料汽油(WPG)进行了表征,并与运输燃料标准进行了比较。将低密度聚乙烯(LDPE),高密度聚乙烯(HDPE),聚丙烯(PP)和聚苯乙烯(PS)混合在一起,以其质量比表示匈牙利,欧盟和世界各地的塑料需求,因为这些混合物有望成为匈牙利,欧洲和世界的塑料通过热解形成类似汽油的燃料。通常情况下,浪费473–512 g / kg产生了WPG产量,并且在传统的火花点火发动机中对燃料进行了测试,没有进行任何修改或混合燃料。WPG的烯烃含量和蒸馏性能超出了EN228的限制,但其余研究参数均满足要求。根据发动机测试,与商用汽油相比,汽油油耗略有下降(RON = 95);但是,在任何一个小幅增长X也被证明。结果表明,最初的固体废物混合物决定了WPG的组成,并且所用材料的配方可能会影响不同组分的浓度。
