U Minn seeking to license new process to produce isoprene from biomass at high yield; green tires

By mmillikin Researchers from the University of Minnesota, with colleagues at the University of Massachusetts Amherst, have developed a new high-yield process—a hybrid of fermentation followed by thermochemical catalysis—to produce renewable isoprene from biomass.

In the process, fermentation of sugars produces itaconic acid, which undergoes catalytic hydrogenation to produce 3-methyltetrahydrofuran (MTHF). The MTHF then undergoes catalytic dehydra-decyclization to isoprene. This catalytic process dehydrates MTHF to isoprene via several combinations of temperatures, pressures, and space velocities (reactant volumetric flow rate per volume of catalyst) and achieves selectivity of MTHF to isoprene.

The University of Minnesota, through its Office for Technology Commercialization, has applied
