They were produced and stabilized by Galvis, who affixed them to a special material. This made the catalyst more durable and made it a more efficient means for converting biogas into the bio-based building blocks, including ethylene and propylene. Process efficiency is a rate of about 60 percent lower olefins by carbon weight of the final products.
The catalyst's production depends on the Fischer-Tropsch synthesis, which has been used in the creation of fuels and chemicals, and is crucial in turning biomass into plastics. (You can access a video describing and illustrating this synthesis and its importance to the new catalyst here.)
The Utrecht University research team expects to continue developing the catalyst with the help of Dow Benelux. Still to be done are larger-scale testing and pilot projects. The team expects the first products made with the new technology to be launched over the next few years.
