Study of the Effect of Temperature on the Rheological Characteristics of Composite Fuel. French-Ukrainian Journal of Chemistry, 11(2), 1–7. https://doi.org/10.17721/fujcV11I2P1-710.17721/fujcV11I2P1-7https://ir.library.knu.ua/handle/15071834/25351The article is devoted to the study of the patterns of change in the rheological characteristics of composite fuels based on low-ash anthracite at a mass fraction of the solid phase of 40%, an oil phase concentration of Co = 49%, a water concentration of CH2O = 10%, and 1% of a chemical additive with an increase in temperature from 10 to 70 °C. It has been established that the dependence of the rheological characteristics of composite fuel on temperature indicators is complex. When the temperature changes from 20 to 30 °C, a plateau is observed (the change in the Kμt coefficient is ≈0.9), which has a significant deviation from the approximation dependence for calculating the Kμt coefficient. From the data obtained, it can be concluded that this type of fuel can successfully compete with traditional types of liquid fuel.encomposite fuelrheological propertiescoalmotor oilsviscositytemperatureСтаття
