Reason and Goal

Against the background of climate change and global warming, the drastic reduction of emissions of so-called greenhouse gases is one of the most important environmental policy goals. However, despite increasing electrification and decreasing energy requirements (efficiency, building insulation), liquid fuels will continue to be indispensable in the future. In order to achieve the goal of a largely GHG-neutral energy and raw material supply, the "carbon footprint" of the energy sources used must be reduced by replacing fossil raw materials with renewable biogenic or CO2-neutral synthetic products. Conventional fatty acid methyl esters (FAME) are only suitable to a limited extent for fuel oil applications, but also as a substitute for diesel, primarily because of their poor storage stability and strong water affinity (corrosion). For an extensive substitution of fossil fuels, innovative, sulphur- and aromatic-free paraffinic components are required. Among other things, paraffinic products are characterised by outstanding technical properties especially for middle distillate applications. Previous investigations, however, surprisingly showed application-technical conspicuous features for fuel mixtures of isomerised hydrogenated vegetable oils and extra-light fuel oil. For example, significant amounts of deposits were found in the pump and nozzle filter when using mixtures of equal parts. A major objective of the proposed project is to clarify the causes of the interactions between the fuel components and the mechanism of deposit formation, and to develop appropriate prevention strategies. In addition, various synthesis routes for paraffinic fuels are being investigated in order to be able to manufacture products with precisely defined properties.

Summary

The aim is to establish alternative fuel components with high CO2 reduction potential as substitutes for fossil middle distillates in the heating market.

The planned project is to focus on the following main areas:


  • Application behaviour of paraffinic fuels or their blends with conventional heating oil extra light,

  • Investigation of causes and mechanisms of deposit formation when using fuel mixtures and development of strategies to avoid them,

  • Process-related investigations for the production of alternative paraffinic fuel components.
