A method to detect a phase separation of gasoline and ethanol may include the steps of generating a sound signal in a tank, determining a speed of the sound signal, determining an interface level in the tank, determining the speed of the sound signal below the interface level and determining...
Studies at the Pacific Northwest Terminal, where 72 m3 of ethanol was released into an existing hydrocarbon plume, indicate that ethanol reduced the surface and interfacial tension and resulted in a significant change in the size, shape, and saturation of the existing gasoline pool (McDowell et ...
Gasoline direct injection engines – A review of latest technologies and trends. Part 1: Spray breakup process 2.2 Mathematical models The simulation of an injection process involves the solution, besides the gas phase fluid-dynamic governing equations, of the so-called spray equation that describes ...
The direct conversion of ethylene to propylene or a combination of value-added chemicals, including butylenes and oligomers in the range of gasoline and diesel fuel, provides the capability of responding to the fluctuations in the balance between supply and demand of the main petrochemicals. A ...
Interestingly, so far there has no application in oily matrix (such as oil, plant oil, gasoline). Actually this is understandable that, compared with in aqueous matrix, the hydrophobic interaction between analytes and mixed hemimicelles are competition and interference in oily matrix. Conclusions ...
Methanol, while effective if used essentially pure for transportation fuel, is not a good additive for gasoline. Ethanol has shown promise as a gasoline additive, but isobutanol in particular is valuable as it can be dehydrated to isobutylene and reacted with methanol to form methyl t-butyl ...
Reaction systems of interest include hydrogenations, for example of 2-butyne-1,4-diol [134], nitrobenzoic acid [135], α-methyl styrene [136], benzaldehyde [137], pyrolysis gasoline [138] and oxidations such as of glycerol [139], glucose [140] and ethanol [141]. However, one of the ...
The invention also discloses a method for preparing the ethanol gasoline phase stabilizer. The ethanol gasoline phase stabilizer of the invention can effectively improve the phase stability of ethanol gasoline products; when the ethanol gasoline phase stabilizer is used, the ethanol gasoline product is...
