Abstract: The use of conventional fuels for heat, energy, or motion production is largely determined by the concentration of water in the fuel. Therefore, the knowledge of the moisture content is of particular importance for combustion efficiency. Specifically, the presence of water in fuels can cause corrosion, and during preheating the water vapor can cause extinguishing of the flame, while at low temperatures it can cause blockage of the network by ice that can be formed. In general, the presence of water can contribute to the development of organic and inorganic substrates that may contribute to fuel turbidity, a fact that is addressed by the addition of chemical additives. In the present work, the possibility of removing moisture from heating diesel fuel through the properties of ionic and non-ionic organic polymers, namely polyvinyl alcohol (PVA) and polyethylene oxide (PEO), was studied. The experimental data obtained by the addition of the polymers to the diesel showed that the fuel’s physicochemical properties were within the suitability limits, while the moisture content was decreased from 62 mg/kg to 50 mg/kg and 53 mg/kg, respectively, for PVA and PEO polymers. A mathematical expression of adsorption was used to simulate the experimental findings. In addition, the sulfur content was decreased from 941 mg/kg to 937 mg/kg when PVA was used. The methodology proposed for improving the physicochemical properties of heating diesel through organic polymers can optimize its combustion behavior to be more environmentally friendly.
