The Effect of Blending Alcohol in Gasoline on Physical and Chemical Properties

There are two basic incentives to blend alcohol in gasoline i.e.

1. 1.
   as a fuel extender to reduce the amount of gasoline used.
2. 2.
   to improve the octane quality of gasoline.

This paper is concerned with the study on the blending effect of ethanol in premium gasoline produced in Indonesia, especially on its physical and chemical properties, and the improvement of its octane number.

The blendings were made in four concentrations (e.g. 5, 10, 15 and 20% volume ethanol in premium gasoline).

The test results will be compared to the Indonesian specification of premium gasoline.
