The present work is focused on pyrolysis of polystyrene waste for production of combustible hydrocarbons. The experiments were performed in an indigenously made furnace in the presence of a laboratory synthesised copper oxide. The pyrolysis products were collected and characterised. The Fourier transform infrared spectra showed that the liquid fraction contains C-H, C-O, C-C, C=C and O-H bonds, which correspond to various aliphatic and aromatic compounds. Gas chromatography-mass spectrometry traced compounds ranging from C1 to C4 in the gaseous fraction, whereas in the liquid fraction 15 components ranging from C3 to C24 were detected. From the results it has been concluded that CuO as a catalyst not only increased the liquid yield but also reduced the degradation temperature to great extent. Fuel properties of the pyrolysis oil were determined and compared with standard values of commercial fuel oil. The comparison suggested potential application of pyrolysis oil for domestic and commercial use.

聚苯乙烯废料的热解，以氧化铜为催化剂回收可燃烃。

目前的工作集中于聚苯乙烯废料的热解以生产可燃烃。实验是在实验室合成的氧化铜存在下，在本地制造的熔炉中进行的。收集热解产物并进行表征。傅立叶变换红外光谱表明，液体部分含有CH，CO，CC，C = C和OH键，分别对应于各种脂族和芳族化合物。气相色谱-质谱法检测到的气态馏分中C1至C4范围内的化合物，而液体馏分中检测到C3至C24范围内的15种组分。从该结果可以得出结论，作为催化剂的CuO不仅增加了液体产率，而且还大大降低了降解温度。确定热解油的燃料性质，并将其与商业燃料油的标准值进行比较。比较表明热解油在家庭和商业用途中的潜在应用。
