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.
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.
