Polyoxymethylene ethers (POMEs) are low-carbon diesel fuels that have very low soot emissions. However, conventional POMEs have methyl endgroups and are undesirably water-soluble. In a new paper published in Fuel we show that POMEs with endgroups derived from isobutanol and fusel oil have better water-solubility while retaining the soot reduction benefits. This work was done in collaboration with Dan Ruddy’s group at the National Renewable Energy Laboratory. The paper is available at https://doi.org/10.1016/j.fuel.2023.130353.
