The aim is to produce these fuels in a climate-neutral way, i.e. with energy that comes exclusively from renewable sources such as wind power and photovoltaics. Then a greenhouse gas reduction can be achieved by successively or completely replacing mineral oil-based heating oil with paraffinic fuels. However, it must first be ensured that the paraffinic fuels are fully compatible with the technology and components of oil heating systems. In marketed fuel oils, low sulfur, the content of aromatic hydrocarbons ranges from 23 to 39% by mass, while paraffinic fuels contain less than 1% aromatic hydrocarbons. These hydrocarbons are absorbed by some plastics without adverse consequences. It is not known what happens when pre-contaminated polymers come into contact with paraffinic fuels. The upcoming research project will investigate how paraffinic fuels, and in particular a switch from mineral oil-based fuel oil to paraffinic fuels, affect the stability of plastics. The investigations of possible effects of such switching include both pre-contaminated polymers from existing and new plants.
The findings obtained in the research project can be incorporated into the development activities of companies in the heating and component construction sector. In addition, they can be incorporated into the development of standardized test methods for demonstrating the resistance of the components of oil consumer systems to mixtures of middle distillates and synthetic paraffinic components.
