Abstract

In recent years, plastic has emerged as a widely used material, replacing traditional materials across various industries due to its versatility and convenience. However, this extensive adoption of plastic has resulted in significant environmental challenges, especially in managing mixed plastic waste. To address this, energy recovery technologies have been developed to offer alternative recycling methods for plastic waste. This study specifically focuses on producing hydroprocessed plastic pyrolysis oil from mixed waste plastic to create environmentally compliant fuel. The scrutiny compares the resultant fuel with diesel using hydroprocessing techniques and catalytic pyrolysis. Physicochemical characterization and GC–MS analysis compare the properties and compositions of MPPO, HPO, and diesel fuel. The waste polymers, which included HDPE, PP, and LDPE, were hydroprocessed and pyrolysed using platinum sulphate on zirconia oxide supports to produce a diesel equivalent. The alkane content of the blended fuel that was produced was 95 % that of diesel. The n-alkane levels in the carbon number ranges C11–C15 and C16–C20 were, respectively, 25 % and 10 % lower than diesel. But as one might expect from mixing heavy fuel oil, there were substantially more n-alkanes with carbon numbers of C21–C25. The combined fuel contained 10 % fewer isoalkanes than diesel. Ships can be powered by low-carbon fuel that was created by combining hydroprocessed fuel with commercial heavy fuel oil. Since the alternative fuel will emit considerably fewer emissions, the maritime industry can choose to replace it in order to help fulfil.

提高废塑料的柴油产量:Pd/MCM-48 催化加氢处理研究
近年来,塑料因其多功能性和便利性,已成为一种广泛使用的材料,取代了各行各业的传统材料。然而,塑料的广泛应用带来了巨大的环境挑战,尤其是在管理混合塑料垃圾方面。为解决这一问题,人们开发了能源回收技术,为塑料垃圾提供替代回收方法。本研究特别关注从混合废塑料中生产加氢处理塑料热解油,以制造符合环保要求的燃料。研究比较了使用加氢处理技术和催化热解技术生产的燃料和柴油。理化表征和气相色谱-质谱分析比较了 MPPO、HPO 和柴油的特性和成分。废聚合物(包括高密度聚乙烯、聚丙烯和低密度聚乙烯)经过加氢处理,并在氧化锆支撑物上使用硫酸铂进行热解,生产出柴油等效物。生产出的混合燃料的烷烃含量是柴油的 95%。碳原子数范围为 C11-C15 和 C16-C20 的正烷烃含量分别比柴油低 25% 和 10%。但正如人们对混合重油的预期一样,碳原子数为 C21-C25 的正构烷烃含量要高得多。混合燃料中的异构烷烃含量比柴油少 10%。通过将水处理燃料与商用重油混合制成的低碳燃料可以为船舶提供动力。由于这种替代燃料的排放量要少得多,因此海运业可以选择替代这种燃料,以帮助实现 "可持续发展 "的目标。

期刊介绍: Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
