Abstract The recycling of plastic waste is a good idea for countries which concern air pollution, CO2 emission, and public health. In this research article, PET, as one of the significant plastic waste, was selected to dissolve in phenol for value‐added liquid fuels and hydrogen gas production. This research aims to provide insight into the mechanism of PET waste and phenol steam reforming reaction. The catalytic steam reforming of PET dissolved in phenol employing Ni-Pt/Al-Ti catalyst was conducted in a fixed bed reactor. The reaction test illustrated that Ni-Pt/Al-Ti catalyst possesses high activity and stability in a long time on stream experiment. It was found that valuable liquid fuels such as styrene, acetic acid, benzoic, benzene, and many other components successfully produced from the PET-phenol steam reforming reaction. It was found that during the catalytic reforming of PET, several types of reactions such as dehydrogenation reaction, thermal cracking, steam reforming, water gas shift reaction, carbenium ion reaction, free radical reaction, dihydroxylation reaction, and coke formation occurred.

废塑料聚对苯二甲酸乙二醇酯（PET）溶解苯酚水蒸气重整制氢及有价值液体燃料的反应机理探索

摘要 对于关注空气污染、二氧化碳排放和公共卫生的国家来说，回收塑料垃圾是一个好主意。在这篇研究文章中，PET 作为一种重要的塑料废物，被选择溶解在苯酚中，用于增值液体燃料和氢气生产。本研究旨在深入了解 PET 废料和苯酚蒸汽重整反应的机理。采用Ni-Pt/Al-Ti催化剂对溶解在苯酚中的PET进行催化蒸汽重整在固定床反应器中进行。反应试验表明Ni-Pt/Al-Ti催化剂在长时间的在线实验中具有较高的活性和稳定性。发现通过PET-苯酚蒸汽重整反应成功地生产了有价值的液体燃料，例如苯乙烯、乙酸、苯甲酸、苯和许多其他组分。
