A Slovak university has developed an additive for improving the cetane number in diesel or biodiesel fuels with a significant effect on the reduction of ignition delay of fuel engines

Country of Origin: Slovakia
Reference Number: TOSK20181004001
Publication Date: 5 October 2018

Summary

A research team from the Slovak university has developed an innovative additive for improving the cetane number of diesel and biodiesel fuels. Improvement of cetane number has a significant effect on the reduction of ignition delay of fuel engines. The additive is based on bio-components, making it possible to increase the quality of fully ecological fuel. The university is looking for partners through license agreement or commercial agreement with technical assistance.

Description

Cetane number is a significant factor in the quality of the diesel fuels and has direct effect on reducing the fuel ignition delay after the injection into the combustion chamber. As a result of the short delay, the engine runs smoothly, with lower noise levels and decreased volume of flue gas in the exhaust phase. The production process of the fuel additive utilizes a product of renewable sources - glycerol, which is in surplus on the market, as it arises as a by-product of fatty acid methyl esters (bio-components for diesel fuel). Using the proposed additive helps to achieve the European Union limits on bio-component content in motor fuels. European Standard EN 590 prescribes minimal cetane number of 51 for produced diesel fuels. Using the proposed fuel additive allows you to increase the cetane number of fuel by several units.

The innovative diesel fuel additive is applicable in the production of oil-based diesel or biodiesel fuels. Improvement of the fuel quality has positive effects on the performance and operation of the engine, as well as on the environment, as it utilizes products of renewable sources.

The university is looking for partners - industrial companies - active in the field of oil-based diesel fuels and biodiesel fuels for future manufacturing and commercialization of the technology under licence agreement or for technical cooperation for the development and usage of the technology.

Advantages and Innovations

The main advantage of the proposed diesel or biodiesel fuel additive is the utilization of glycerol, as a product of renewable sources. Thus, the improvement of the fuel quality is also ecological, in accordance with the European Union limits on bio-component content in motor fuels. Lower manufacturing costs are expected in comparison to currently most used diesel fuel additive ethylhexyl nitrate.

Stage Of Development

Available for demonstration

Requested partner

- Type of partner sought:
The university is interested in technology transfer with industrial companies, especially with the companies active in the field of oil-based diesel fuels and biodiesel fuels. Additional details are available on request. In 2014, this technology won the Slovak Price for Technology Transfer in a category "The Best Implemented Technology Transfer". The university is seeking industrial partners for collaboration on any of the following levels:
• Manufacturing and commercialization under license agreement - this additive based on bio-components helps to achieve the European Union limits on bio-component content in motor fuels. The technology is patented in Slovakia and the European patent application was submitted-
• Technical cooperation for the development and professional use of the technology

- Specific area of activity of the partner:
Oil-based diesel fuels, biodiesel fuels

- Task to be performed:
• future technology transfer, the selling of the technology
