Audi synthesizes e-benzin without petroleum

Audi, along with Global Bioenergies, has developed ‘e-benzin’ through synthetic methods in a lab without the use of petroleum or any of its by-products. As this e-benzin is made out of 100 percent iso-octane, it has a high octane rating of RON 100. As this is a high-grade fuel for vehicles, engines can be made with high compression a ratio which in turn enhances fuel efficiency. Audi e-benzin has no sulphur or benzene it combusts absolutely cleanly. For now, Audi will be testing this new fuel in the lab feeding it to test engines. Yet again Audi stands in the forefront in developing sustainable clean energy for automobiles.

Reiner Mangold, Head of Sustainable Product Development, AUDI AG, said “Global Bioenergies has demonstrated the viability of the Audi “e-benzin” production process. That is a big step in our Audi e-fuels strategy.” Audi is already producing larger quantities of “e-gas” (synthetic methane) on an industrial scale for its customers. Other research projects with various partners are dedicated to Audi “e-ethanol”, Audi “e-diesel” and Audi “e-benzin”.

The pilot plant for the production of this isobutene, base material for Audi ‘e-benzin’, is in the French town of Pomacle, near Reims. Also this Isobutene is processed out of renewable raw materials instead of usual petroleum. Another project partner is the Fraunhofer Center for Chemical-Biotechnological Processes (CPB) in Leuna, Saxony-Anhalt. Researchers there use hydrogen to transform the gaseous isobutene into liquid iso-octane. Global Bioenergies is building a demonstration plant at the Fraunhofer Center that will begin producing larger quantities in 2016.

Abhijeet

<p> </p> <p class="western" lang="en-GB">Since his early days, Abhijeet Singh has always been considered a mentalist for speed. He reserves a nice sounding engine as a symphony orchestra. Recognised as a bit left field thinker, he states that all iconic vehicles on the planet, apart from their engines and designs, had a soulful character contributing to their greatness. Having driven cars from Lamborghinis to Nanos to even tractors, Abhijeet believes all vehicles have a character that forms an integral part of our lives, ‘imagine where mankind could have reached without cars’. Being a critic, his knowledge and skill extend both on four-wheels and two-wheels. Art experts around the globe argue that cars can never be art, but Abhijeet begs to differ. Also an avid photographer, he mentions that through the lens of an artist, cars are one of the most beautiful subjects. Both an engineer and MBA, he holds a keen eye for the product as well as corporate proficiency of the automobile industry.</p>Read more
