Maximize the Production of Environmental, Clean and High Octane Number Gasoline-Ethanol Blends by using Refinery Products [ ]


Gasoline produced in Egypt is a low-grade gasoline that contains a high concentration of harmful components that are having a toll on our environment. In addition, those pollutants cause countless diseases and deaths annually to the Egyptian population. This paper investigates the effect of ethanol-gasoline blends on fuel properties characteristics using standard laboratory methods. Fuel properties tests are conducted for density, RVP, ASTM distillation, RON, MON, PON, PIONA, and benzene content of ethanol-gasoline blends with different percentages of ethanol. Straight run naphtha, isomerate, reformate, Coker naphtha and hydrocracked naphtha which produced from crude distillation unit, isomerization process, catalytic reforming and conversion processes respectively are blended with an oxygenated compound ( ethanol) to produce environmental gasolines A98 and A95 respectively which satisfy all specification of Euro-6 regulations. The new blends are friendly environmental and contains the less amount of benzene content. Fuel properties test-results showed that blends densities increased continuously and linearly with increasing percentage of ethanol, while Reid Vapor pressures decreased. Furthermore, ASTM distillation curves for blends are found to be lower than pure gasoline fuel. The tested blends Octane rating based on Research Octane Number (RON) increased continuously and linearly with increasing the percentage of ethanol. Results from this study will be valuable on the assessment of the suitability of ethanol-gasoline blends as bio-fuel for the automotive industry to cover for the country demands.
