- Bio-MTBE is produced from isobutene and biomethanol.
- Biomethanol is classified as a waste product under the EU Renewable Energy Directive.
- Bio-MTBE offers high energy density, low vapor pressure, and low oxygen content.
- Evonik's plant can produce up to 550,000 metric tons of Bio-MTBE per year.
Introduction of Bio-MTBE
Evonik has introduced Bio-MTBE, a biological version of the premium antiknock agent MTBE, offering oil companies a new way to increase the biocontent of their fuels and reduce carbon emissions. Bio-MTBE is produced at Evonik's facility in Marl, Germany, alongside conventional MTBE.
Production Process
Bio-MTBE is synthesized from isobutene and biomethanol. Biomethanol, derived from raw glycerine—a co-product of biodiesel production—is classified as a waste product under the EU Renewable Energy Directive (RED), enhancing its value for bioenergy content calculations.
Technical Advantages
Bio-MTBE retains the technical benefits of conventional MTBE, including high energy density (86% of gasoline), low vapor pressure, low oxygen content, and minimal water solubility. These properties ensure compatibility with other gasoline components and safe handling in refineries and storage facilities.
Market Potential
Currently, Evonik primarily markets Bio-MTBE in Germany and the Netherlands. However, the implementation of EU biofuel directives in other member states could expand its market potential. Evonik's plant has the capacity to produce up to 550,000 metric tons of Bio-MTBE annually if required.
