“…To prove this, immersion tests are carried out on metals and other materials used in the fuel system to determine corrosion resistance to ethanol contained in fuels. The results of this study indicate that high ethanol concentrations cause corrosion in fuel system components made of aluminum [35].…”

The rate of Indonesian oil imports has increased from 1980 to the present, despite fluctuations. The transportation sector is the largest oil consumption above the industrial and household sectors. The availability, price, and environment factors also make a reason to think about cleaner fuels. Therefore, we conducted a review of the experience of implementing alternative fuels. At present, LPG, CNG, ethanol and biodiesel are good candidates to replace conventional fuels for land transportation in Indonesia. For gas-based fuels, LPG is relatively easy to implement because it only requires a slight modification to the engine but it is not suitable for the future because it is a refinery product. CNG provides advantages over LPG. The lower carbon content and high octane number provide better environmental effects and can be applied to machines with a higher compression ratio. For biofuels, ethanol has almost all the main characteristics for cleaner SI engine fuels. Indonesia has abundant biodiversity to produce ethanol. However, large-scale production will conflict with the availability of land for food crop production. Biodiesel has been produced on a large scale in Indonesia. Palm oil, Jatropha curcas, sunflowers and all seeds containing oil can be planted on all islands in Indonesia. One feature of biodiesel is that it can be applied independently or mixed with diesel oil. With improved quality, biodiesel can be applied to diesel engines without engine modification. This makes biodiesel more feasible for diesel engines than ethanol for gasoline engines.

“…The use of alcohols in blends with gasoline involves some practical aspects that must be considered. Alcohols tend to be corrosive, especially the ones with shorter molecules [51], which can damage fuel system components. The corrosiveness of methanol is particularly well-documented [52].…”

Certain oxygenated compounds, when blended with gasoline, have the ability to inhibit the occurrence and decrease the intensity of engine knock, helping improve engine efficiency. Although ethanol has had widespread use as an oxygenate, higher alcohols, such as butanol, exhibit superior properties in some respects. Besides alcohols, glycerol derivatives such as glycerol tert-butyl ether (GTBE), among others, also have the potential to be used as gasoline oxygenates. This work provides a direct comparison, performed on a modified Waukesha CFR engine, of C1–C4 alcohols and the glycerol derivatives GTBE, solketal, and triacetin, all blended with a gasoline surrogate in different concentrations. The tests focused on how these oxygenated compounds affected the knocking behavior of the fuel blends, since it directly impacts engine efficiency. The test matrices comprised spark-timing sweeps at two different compression ratios, at stoichiometric conditions and constant engine speed. The results showed that, in general, the C1–C4 alcohols and the glycerol derivatives were effective in decreasing knock intensity. n-Butanol and solketal were the noteworthy exceptions, due to their demonstrated inferior knock-inhibiting abilities. On the other hand, isopropanol, isobutanol, and GTBE performed particularly well, indicating their potential to be used as gasoline oxygenates for future engines, as alternatives to ethanol.

“…The interest in new biofuels based on light alcohols has increased in recent years, making necessary the storage and purification of these compounds . Methanol, ethanol, propanol, and butanol have industrial interest since they can be used in internal combustion engines as biofuels. − In this regard, the biofuels obtained from organic residues such as sugarcane or crops are a more ecofriendly alternative to fossil fuels. − The capture, purification, and separation of these alcohols are crucial for industrial processes. − Methods like distillation or pervaporation are used in the industry. Distillation is the most extended method to obtain and purify bioethanol .…”

As an alternative option to conventional fuels, biofuels based on light alcohols are receiving great attention. In this context, we investigate the adsorption mechanism of light alcohols in the hydrophobic metal–organic framework MAF-6. To study the effect of the conformation of molecules in the adsorption process, we evaluate the effect of the length of the alkyl chain of linear alcohols (methanol, ethanol, propanol, and butanol) and branched alcohols (2-propanol, 2-butanol, and tert-butanol). We perform Monte Carlo simulations in the grand-canonical ensemble to study the adsorption and energetic properties of the systems. We analyze the structural organization and the nucleation mechanism of the molecules of alcohol and the dynamics of the adsorbed molecules within the big cavities of MAF-6. We found that the initial step of adsorption is governed by the interaction of the adsorbates with the structure, while in saturation, the adsorbate–adsorbate interactions gain importance.
