What Are the Prospects for Further Refining Pyrolysis Oil?

The global waste to energy sector is experiencing significant growth, within this burgeoning industry, pyrolysis oil—derived from waste like tires, plastics, and oil sludge—has emerged as a valuable alternative fuel source. However, crude pyrolysis oil typically contains impurities, possesses high viscosity, and exhibits unstable properties, thereby limiting its direct application in engines or industrial burners. So what are the prospects for the further refining of pyrolysis oil?

Pyrolysis oil to diesel refining system

The outlook for refining pyrolysis oil is exceptionally promising. Fueled by increasingly stringent environmental regulations, rising conventional fuel costs, and a growing global emphasis on circular economy solutions, transforming crude pyrolysis oil into clean diesel or high-quality furnace fuel oil is not only technically viable but also highly attractive from an economic standpoint.

Governments worldwide are intensifying their efforts to regulate and restrict the direct combustion of low-quality alternative fuels due to their environmental impact. Refining pyrolysis oil significantly reduces harmful emissions such as sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter. Furthermore, advanced refining processes minimize the generation of waste oil residues.

While crude pyrolysis oil can be sold as a basic industrial fuel, its market price of $500–$700 per ton is considerably lower compared to refined products. Refining this low-value crude oil into diesel fuels can significantly boost profit margins, as the market price for refined diesel ranges from $1,200 to $1,500 per ton. Refined diesel oil burns more cleanly, contains substantially lower sulfur levels, and complies with stricter emission standards, thereby enabling access to more lucrative markets and a broader range of end-users.

Profit analysis of DOING waste oil refining system

Further refining represents a crucial and highly valuable step in the waste-to-energy process. It converts pyrolysis oil into a cleaner fuel with fewer impurities. This process helps reduce the demand for virgin crude oil extraction, conserves finite natural resources, and plays a vital role in preventing environmental pollution.

Crude pyrolysis oil typically finds limited application, primarily in heavy-duty industrial burners. In contrast, refined diesel derived from pyrolysis oil can power a much wider array of machinery, including agricultural machinery, generators, heavy trucks, and even marine engines. This broadens the potential customer base significantly, opening up markets to diverse clients ranging from local farms to large logistics enterprises.

Applications of diesel from pyrolysis oil refining

The foundational technology behind refining pyrolysis oil is distillation, which efficiently separates lighter hydrocarbon fractions from heavier residues. However, not all distillation systems offer the same level of performance. The pyrolysis oil refining systems are capable of processing a diverse range of feedstocks, including pyrolysis oil, waste lubricants, certain types of crude oil, liquid sludge, and used motor oil.

DOING Group has developed two waste oil refining systems, each carefully tailored to meet varying investment scales and environmental compliance requirements. All our systems feature a modular design, offering flexibility for new investors to start with a smaller setup and gradually scale up their operations as their business grows.

1. Traditional Acid Washing and Clay Bleaching Process:

One established method involves utilizing an acid—typically sulfuric acid—to react with impurities present in the distilled oil, such as gums, asphaltenes, and sulfides. Following this acid treatment, an alkaline liquid is used for neutralization. Subsequently, activated clay is employed to adsorb residual color and polar compounds, resulting in a clearer, more stable fuel. This approach requires a relatively low initial investment, is straightforward to operate, and has been successfully validated across numerous markets globally.

2. DOING’s Innovative Catalytic Refining System:

DOING’s advanced catalytic system employs proprietary catalysts to process pyrolysis oil vapor, remove impurities from it, and then filter it through a filter machine to ultimately obtain diesel. These specially formulated catalysts effectively crack long-chain hydrocarbons while simultaneously removing undesirable sulfur, nitrogen, and oxygen-containing compounds. Our advanced distillation systems are designed to minimize the production of acidic sludge and wastewater, offering a significant environmental and operational advantage over traditional refining methods.

Two types of DOING pyrolysis oil refining systems

DOING offers waste oil refining systems with a wide range of daily processing capacities, from 100 kg, 500 kg, 1 ton, 3 tons, 5 tons, 7 tons, 10 tons, up to 14 tons. This modular design provides substantial advantages for new investors:

Phased Investment: Investors can initially install a smaller system—such as a 100 kg to 3-ton daily capacity unit—to thoroughly test the oil yield of pyrolysis oil refining and the quality of the diesel products, and assess specific market demand without committing excessive capital upfront.

Scalability: Once the operation demonstrates profitability and market demand solidifies, additional parallel units can be easily added, or the existing system can be upgraded to a larger model. This flexible approach eliminates the need for a large initial capital outlay, reducing risk and facilitating sustainable growth.
