Synthesis of Methanol by Hydrogenolysis of Biobased Methyl Formate Using Highly Stable and Active Cu-spinel Catalysts in Slurry and Gas Phase Reactions

Haagen, V. et al.

For the Scientist in You

This abstract discusses a novel method for producing green methanol from biomass by first converting it into methyl formate/formic acid mixtures, and then using Cu_0.9Al₂O₄ spinel materials as an effective catalyst for the hydrogenolysis step.

Unlike traditional catalysts, this spinel material is more stable and does not contain hazardous chromium compounds, making it a promising solution for methanol production from biomass.

For the Rest of Us

This research focuses on creating a more eco-friendly way to make methanol from biomass (like plant materials). The process involves converting biomass into a chemical mixture and then using a special material called Cu_0.9Al₂O₄ spinel as a catalyst to turn that mixture into methanol.

This new catalyst is safer and more stable compared to the old ones, which often contain harmful substances. It’s a promising step toward making cleaner methanol from renewable sources.
