以真实的世界城市固体废弃塑料和模拟的城市废弃塑料混合物为例，在间歇式高压釜反应器中，在中等温度和压力下对废弃塑料进行热解液化。此外，构成欧洲城市固体废物中出现的大多数塑料的五种主要聚合物也发生反应，所述五种主要聚合物包括聚乙烯、聚丙烯、聚苯乙烯、聚对苯二甲酸乙二醇酯和聚氯乙烯。塑料在氮气（热解）和氢气压力（液化）下反应，并报告了产物的产率和组成。产生的烃类气体主要是甲烷、乙烷、丙烷和较低浓度的烯烃气体。用具有显著浓度的芳族化合物（包括单环芳族化合物）的混合塑料废物生产主要为油的产品。油和气体的组成表明，与单一塑料反应的预期结果相比，当它们作为混合物热解和液化时，塑料之间存在显着的相互作用。
Waste plastics in the form of two examples of real world municipal solid waste plastics and a simulated mixture of municipal waste plastics were pyrolysed and liquefied under moderate temperature and pressure in a batch autoclave reactor. In addition, the five main polymers which constitute the majority of plastics occurring in European municipal solid waste comprising, polyethylene, polypropylene, polystyrene, polyethylene terephthalate and polyvinyl chloride were also reacted. The plastics were reacted under both a nitrogen (pyrolysis) and hydrogen pressure (liquefaction) and the yield and composition of products are reported. The hydrocarbon gases produced were mainly methane, ethane, propane and lower concentrations of alkene gases. A mainly oil product was produced with the mixed plastic waste with significant concentrations of aromatic compounds, including single ring aromatic compounds. The composition of the oils and gases suggested that there was significant interaction of the plastics when they were pyrolysed and liquefied as a mixture compared to the results expected from reactions of the single plastics.
