Abstract The current energy industry relies heavily on fossil fuels. As reserves of fossil fuels are diminishing, the demands for alternative forms of energy are growing. Therefore, the search for alternative fuels is crucial. This article discusses pyrolysis gases generated from major plastics as possible future successors to fossil fuels. The novelty of this study lies in the comprehensive discussion of the fuel characteristics of different pyrolysis gases that are so far unpublished. The article builds on Part I, which predominantly focused on the production and physical properties of pyrolysis gases from plastics. Various properties are determined by combining experimental and mathematical methods. An interesting aspect of the gases produced from poly(ethylene terephthalate) (PET) is their high upper flammability limits, which are 61.46% on average. Gases from poly(vinyl chloride) (PVC) are characterized by very high laminar burning velocities, with an average value of 178.62 cm s−1, which is about five times higher than that of natural gas (NG). Gases produced from PVC at 500 and 700 °C have autoignition temperatures almost identical to that of NG. Furthermore, the results presented in this article show that, according to standards proposed by the California Air Resources Board and the Gas Research Institute, none of the pyrolysis gases are suitable fuels for gas engines, because the methane number of no gas meets the minimum value of 65 required in the EU and USA. This article discusses results valuable for determining the potential suitability of pyrolysis gases for use in power-engineering facilities, including combustion engines, and includes information on further research prospects.

由单独和混合 PE、PP、PS、PVC 和 PET 产生的热解气体——第二部分：燃料特性

摘要 当前能源工业严重依赖化石燃料。随着化石燃料储量的减少，对替代能源的需求正在增长。因此，寻找替代燃料至关重要。本文讨论了由主要塑料产生的热解气体，这些气体可能是化石燃料的未来继任者。这项研究的新颖之处在于对迄今为止尚未发表的不同热解气体的燃料特性进行了全面的讨论。本文建立在第一部分的基础上，该部分主要关注塑料热解气体的生产和物理特性。各种性质是通过结合实验和数学方法确定的。由聚对苯二甲酸乙二醇酯 (PET) 生产的气体的一个有趣方面是它们的高可燃性上限，即 61。平均 46%。聚氯乙烯 (PVC) 产生的气体具有非常高的层流燃烧速度，平均值为 178.62 cm s-1，大约是天然气 (NG) 的五倍。在 500 和 700 °C 下由 PVC 产生的气体的自燃温度几乎与 NG 相同。此外，本文中的结果表明，根据加州空气资源委员会和气体研究所提出的标准，没有一种热解气体适合燃气发动机的燃料，因为没有气体的甲烷值满足最小值欧盟和美国要求的 65。本文讨论了对于确定热解气体在电力工程设施（包括内燃机）中使用的潜在适用性有价值的结果，
