Researchers have discovered a method to utilize a glycerol component to create bio-based propylene.
To achieve carbon neutrality, it’s essential to make effective use of renewable biomass. For example, during biodiesel production, glycerol is produced as a significant byproduct. The team at Osaka Metropolitan University has invented a new catalyst that effectively transforms a glycerol derivative into bio-based propylene, thus aiding in sustainable chemical manufacturing.
Typically, propylene is derived from petroleum and is extensively employed in the production of plastics, including items like car bumpers and food containers. The research group, under the guidance of Associate Professor Shin Takemoto and Professor Hiroyuki Matsuzaka from the Graduate School of Science, created a catalyst that targets the selective breaking of the oxygen-carbon bond in allyl alcohol—a glycerol derivative—to yield bio-based propylene.
The innovative catalyst allows for the efficient, selective conversion of allyl alcohol into propylene, utilizing renewable energy sources like hydrogen or electricity. This catalyst incorporates a unique molecule known as a metalloligand, specifically designed to support the reversible attachment of two metals within the catalyst. This capability boosts reaction efficiency, ensures high selectivity, and reduces the production of unwanted byproducts.
“Our findings present a sustainable alternative to traditional methods of propylene production, contributing to a greener chemical industry,” remarked Professor Takemoto. “We are excited to further advance this technology and investigate its wider applications.”
