Influence of methanol in physio chemical properties of gasoline fuel mix and impact of surfactant

Siddhartha Mitra

Introduction of bio fuels from renewable source is an alternate to reduce global warming, hydrocarbon emissions, minimise the use of petroleum reserve and blending of alcohol was started without modifying the vehicle design. Addition of low chain alcohol in gasoline increases the vapour pressure considerably and exhibits an azeotrope characteristics that effects severely on distillation parameter. An experiment done on blending of methanol in different volumetric proportion (5%, 10%, 15%, 20%, 25%) with hydrocracked gasoline then influence on volatility performance and distillation properties were studied. Physical characterisation of different blends were studied for vapour pressure (VP), VLI, DI and distillation. This fuel-alcohol blends exhibited rise in recovery at 700C (E70), VP, VLI and area of azeotrope with increase in % of alcohol volume in gasoline blend
