The components of the organic phase contained tert-butanol(TBA), isobutylene (IB), di-isobutylene (DIBs), tri-isobutylene (TIBs) and HCs (hydrocarbons) while the components of the aqueous phase contained water, the unconverted tert-butanol and glycerol.
Setting a higher conversion of glycerol as the operating objective, the optimal operation conditions were found (reaction time 8 hours, reaction temperature 190 and TBA/glycerol molar ratio 2) and a maximal conversion of glycerol (60%) was achieved. By a simple distillation of the organic phase, two cuts (the distillate cut with the boiling point less than 225℃ and the residue cut ) were obtained. The distillate cut could be used as an octane booster for gasoline because its octane number was higher than 100. Meanwhile, the residue cut could be adopted as a diesel fuel because its cetane index was 32 and possessed excellent cold filter plugging point (-19℃) and the pour point (-42℃).
