In a groundbreaking study, Leszek Chybowski from the Department of Marine Propulsion Plants at the Maritime University of Szczecin has shed light on the potential of tire pyrolysis oil (TPO) as a game-changer in the maritime fuel industry. The research, published in the journal Energies, delves into the properties of diesel blends infused with TPO, focusing on how these blends impact engine wear and tear. The findings are a breath of fresh air for an industry grappling with emissions and sustainability challenges.
Chybowski and his team explored diesel blends with TPO content ranging from 5% to 20% by mass. The goal? To see if these blends could minimize engine wear while meeting stringent regulatory standards. The results are promising. Blends with up to 20% TPO met most of the requirements set by the International Maritime Organization (IMO) and the MARPOL Convention. This means these blends could be a viable alternative to conventional fuels, especially in areas outside the Sulphur Emission Control Areas (SECA zones).
One of the standout findings is the improved lubricity of the fuel blends. As Chybowski notes, “Increasing the TPO content in the blends has a positive effect on the lubricity of the fuel, which is presumably due to the presence of sulfur and the complex hydrocarbon composition of TPO.” Better lubricity means less wear and tear on engine components, translating to longer engine life and reduced maintenance costs.
However, there are some hurdles to overcome. The study found that the ash content in the blends exceeded normative limits, which could lead to increased wear and corrosion of engine components. Chybowski suggests that additional fuel treatment, such as desulfurization and advanced filtration, could mitigate this issue. “Post-recycled oils must, therefore, undergo appropriate purification before being used as an additive to diesel fuels for internal combustion engines,” he states.
The commercial implications are significant. Maritime companies could see substantial cost savings by using TPO blends, especially in areas where sulfur reduction systems like scrubbers are not required. Moreover, the use of TPO aligns with sustainable development strategies, reducing the environmental footprint of the maritime industry.
The study also opens doors for innovation in fuel purification technologies. As the demand for cleaner, more sustainable fuels grows, so too will the need for technologies that can effectively purify and treat alternative fuels like TPO. This presents a unique opportunity for tech companies and startups to develop and commercialize advanced purification systems.
In summary, Chybowski’s research offers a compelling case for the use of TPO in diesel blends. While there are challenges to address, the potential benefits for the maritime industry are clear. As the industry continues to seek sustainable solutions, TPO could very well be the fuel of the future. For those eager to dive deeper, the full study is available in the journal Energies.
