Supercritical reaction between methanol and glycerol: The effects of reaction products on biodiesel properties

This work investigated the supercritical reaction between glycerol and supercritical methanol (SCM) in non-catalytic biodiesel production process. Glycerol is a by-product of biodiesel production that could react with SCM, producing glycerol ethers (GEs). Simultaneous conversion of triglycerides and...
