摘要: Abstract Four hydrocarbon-base gasolines (BG) were formulated from the local refinery streams; isomerate, reformate, and light naphtha. The formulations enriched in reformate. Each of these BG was blended with 10 vol% anhydrous ethanol. From ASTM-D86 distillation data, eight curves constructed trend line equations developed. Also, area under each curve (AUDC) calculated through calculus definite integration technique. Subsequently, due to azeotrope formation (ADAF) for BG-ethanol blend estimated. In this paper, influence increasing reformate proportions on created positive azeotrope, studied. Also vapor pressure, Temperature vapor-liquid ratio 20, T50 octane number results show that R2 values prove reliability fits. proportion fuel improves while decreases volatility formulation.
