Stability Characteristics of Water/Diesel and Biodiesel Emulsions Under the Influence of Water Dosages

The data in this article present the effective parameters of experimental microscopic processes to investigation of the emulsifiers stability characteristics with changing the water dosage in diesel/or biodiesel fuel. As a result of the increasing demand to improve the fossil fuels properties and the application of the emulsification procedure by adding water dosages into fuel as the promising idea, it opened the way to research in identify many affecting factors these emulsions; one of the important emulsion features was stabilization period and the increasing water dosage rate in emulsion how effected on this feature was not been effectively studied. The current work interested to study the distribution of water droplets (droplet size) in the W/D (water/diesel) or W/BD (water/biodiesel) emulsions. The datasets were gained during experiments conducted with using digital microscopic image technique for five samples of W/D and W/BD emulsions 5, 10, 15, 20, and 30% (v/v) water content, Here, the experimental set-up and the major instruments used for obtaining the computed data were explained in details. The results were appeared that, the larger the amount of water content in the emulsion, the brighter milky emulsion produced. The experiments indicated that increasing the water dosage in W/D and W/BD emulsions influenced negatively on the emulsion stabilization period.
