摘要

随着化石燃料储量的迅速枯竭和能源需求的不断增长,回收炼油厂的重油残渣和其他石化衍生物(如塑料废料)是一种尚未开发的能源回收原材料。可以采用有效且环保的热解技术方法来生产可再生能源。对重石化残渣和废塑料进行联合热解,以确定其物理和化学特性,并了解产品的应用前景。在我们正在进行的研究中,我们目前正在对通过在恒温环境下同时处理塑料废料和残余燃料油(RFO)而产出的液体进行分类。我们利用碳-13、质子核磁共振(13C NMR &1H NMR)、凝胶渗透色谱法(GPC)、终极分析仪、傅立叶变换红外光谱法(FTIR)和炸弹量热法等表征技术对液体产出产品进行了表征。此外,还研究了燃料的特性,包括倾点、闪点和密度。研究结果表明,共热解作用导致分子量明显降低,质子化芳香族碳含量下降,以脂肪族复合物为主要成分的脂肪族碳含量(饱和)增加。经测量,共处理产生的液体倾点在 18-25 ℃ 范围内,而通过共热解产生的液体样品的热能在 43-45 兆焦/千克之间。通过这项研究发现,废聚合物与 RFO 的共热解可以作为废物回收的另一种途径,从而实现可持续的解决方案,并将废物转化为有价值的二次增值化学产品和能源。

Liquid Products from Ternary, Quaternary, and Quinary Co-pyrolysis of Waste Plastics and Residual Fuel Oil: Characterization and Potential Applications

Liquid Products from Ternary, Quaternary, and Quinary Co-pyrolysis of Waste Plastics and Residual Fuel Oil: Characterization and Potential Applications

With the rapidly depleting fossil fuel reserves amid growing demand for energy, recycling heavy fuel residues from refineries and other petrochemical derivatives like plastic waste, which are available in abundance, can be an unexplored raw material for energy retrieval. Effective and environmentally friendly methods of pyrolysis technique can be employed to generate renewable energy. Co-pyrolysis of heavy petrochemical and waste plastics petrochemical residues to establish their physical and chemical characteristics and apprehend the prospective of the products for possible applications. In our ongoing research, we are currently categorizing the consequential liquid output through the simultaneous treatment of plastic waste alongside residual fuel oil (RFO) in a constant temperature setting. Characterization techniques, including Carbon-13, Proton NMR (13C NMR &1H NMR), Gel permeation chromatography (GPC), ultimate analyzer, Fourier transforms infrared spectroscopy (FTIR), and bomb calorimetry were utilized to characterize the liquid yield products. Further, fuel properties, including pour point, flashpoint, and density, were also investigated. The study revealed a significant reduction of molecular weight as a consequence of Co-pyrolysis, a drop in the protonated aromatic carbons, and an upsurge in the abundance of aliphatic carbons (saturated) with aliphatic complexes as the chief component was witnessed in the spectrum. The pour point of the liquid derived from co-processing was measured to be within the range of 18–25 °C, while the calorific energy of the liquid sample generated through Co-pyrolysis was determined to fall between 43–45 MJ/kg. Through the study, it has been discovered that co-pyrolysis of waste polymer with RFO can be an alternative route of waste recovery for sustainable solutions and the transformation of waste into valuable secondary added-value chemical products and energy sources.
