Improve the Octane Number of Gasoline and Studying the effect of Reid vapor pressure and Calorific Value by using Environmental additives

Abstract

An assessment was made for the impact resulted by the addition of (DO) and (DOA) on the octane number and Reid vapor pressure (RVP) of gasoline with different chemical compositions. The locally produced gasoline had been blended with three different ratios (v/v) of the additives, i.e. 8, 10 and 15%. The octane rating of gasoline was observed to continuous increased and linearly with the addition of (DO and DOA). The DOA-gasoline blends produced higher octane number. The two additives observed that decreased significantly the RVP and CV of the original fractions when blended with gasoline. However, additives were add in (8, 10, 15%vol) to gasoline blend, increasing RON was (0.9-23.9).
