Separation of bio-oil by molecular distillation - ScienceDirect

May 01, 2009 Molecular distillation of bio-oil at 70 C, 100 C and 130 C were investigated in this study to explore the effects of the evaporation temperature on the separation of compounds. The bio-oil was divided into three fractions: light, middle and heavy fractions. All samples were kept under − 4 C in the refrigerator.
