Abstract

In this research we explore the feasibility of using commercial gasoline to extract the ethanol from the ethanol solution to produce gasohol. The experiment simulated a 3-stage countercurrent extraction process. Commercial unleaded gasoline with various octane number (92,95,98) was used as solvent to extract the ethanol from ethanol solutions with 80% 90%(v/v) of the ethanol content. The experimental results showed gasohol with more than 10% (w/w) the ethanol content could be gotten. The phase diagram was also observed at low (0~1 ) and room temperature. We found that phase diagrams of water-gasoline-ethanol systems with various octane number of gasoline had no significant difference and the solubility of gasoline in water phase increased with the increase of temperature. It is clearly that gasohol can be produced by extracting the ethanol with commercial gasoline. This process can significantly reduce the energy consumption for the ethanol distillation process. It is a simple and feasible method to produce gasohol.
