We developed a glycerol inhibition process for use in diesel fuel production from animal fats and vegetable oils. Optimal reaction conditions were investigated for the pyrolysis and methylation of glycerol and their effect on product inhibition was clarified. We evaluated reaction conditions and considered glycerol, mono-, di-, and triglyceride content, fatty acid methyl ester content, product composition and viscosity. Optimal reaction conditions included a reaction temperature of 440-460 deg C and a mixing ratio of 2:1 (oil:methanol, v/v). It is proposed that the treatment of glycerol waste could be omitted under these reaction conditions.
