Naphthenes vs aromatics
Witryna11 sty 2010 · Real fuels are complex mixtures of thousands of hydrocarbon compounds including linear and branched paraffins, naphthenes, olefins and aromatics. It is generally agreed that their behavior can be effectively reproduced by simpler fuel surrogates containing a limited number of components. In this work, an improved … Witryna26 lut 2024 · Hydrocarbon-based fuels which are gasoline, diesel, natural gas, and liquefied petroleum gas (LPG) have been generally used in the diesel and gasoline engines as a fuel. In this study, hydrocarbon-based fuels such as alkanes (paraffins), naphthenes (cycloparaffins), alkenes (olefins), alkynes (acetylenes), and aromatics …

Witryna1 lut 1995 · Naphthenes, like paraffins and aromatics, are a major component of unrefined fuels. Like these other hydrocarbons, naphthenes' solubility in water is of critical importance to engineers, particularly vis-a-vis the environmental hazard they present when spilled in water. Naphthenes' water solubility is described as a function …
