Processes for Advanced Fuel Production from Biomass — •Jörg Sauer — Institute of Catalysis Research and Technology (IKFT), Karlsruhe Institute of Technology (KIT), Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany
A survey is given of the potential and production pathways of modern low emission synthetic fuels which are required in the context of the "Energiewende". Unlike so-called "1st generation biofuels", technologies for synthetic biofuels are based on carbon-sources that are not competing to the production of food and animal feed. Methanol and Dimethylether (DME) are accessible through state-of-the-art production processes and will be important intermediate components for synthetic biofuels. Ongoing process development for Methanol and DME will lead to increased stability against fluctuations in feedstock and energy supply.
Several strategies are known for the production of fuels from Methanol and Dimethylether, both for oxygen-containing (oxygenate) fuels and oxygen-free fuels (hydrocarbons). The former offer the advantage of clean combustion and reduced emissions, the latter have high energy densities. The oligomeric oxymethylene dimethyl ethers (OMEs) are highly interesting oxygenate components for application as future diesel component. The production and application is still on a comparatively early stage of development. However, they exhibit beneficial combustion properties with potential for emission reduction. Especially OME-3 to OME-5 are targeted due to their favorable physico-chemical properties.
