A vacuum distillation apparatus was developed for distillation of biofuel from microalgal model solution. A residue curve was made to investigate the efficiency of oil distillation, using a modified UNIFAC equation for the calculation. From the results, n-hexane was highly separated from microalgal oil at 40 kPa. Squalane was gradually evaporated with recovery of n-hexane from the feed components.
