Stability and Corrosiveness of M30 Methanol Gasoline
The stability of M30 Methanol Gasoline (30% methanol, 70% gasoline, v/v) under low temperature and metal corrosion were studied in this paper. Kinds of co-solvents were added into M30 for enhancing its stability at different low temperature and the influence of co-solvents on the stability was also investigated. Results showed that the more the content of co-solvent was, the lower temperature of phase disengagement was. When the content of co-solvent was 3%, the n-hexanol added has the lowest phase separation temperature (-27 °C) of any straight chain alcohols studied. Obvious corrosion happened with the copper samples in pure methanol, FCC gasoline and M30. For M30, the biggest copper’s corrosion appears in the first 3 h (weight loss rate 0.67 mg/h). In addition, the separation mechanism of methanol from gasoline was also discussed.
