Preparation and research on properties of castor oil as a diesel fuel additive

The research shows an opportunity of preparing biodiesel fuel on the basis of local diesel fuel and the bioadditive - castor oil. Limiting optimum concentration of introduction of the bioadditive equal was established as 5% mass ratio. The castor oil released from seeds of Palma Christi grown on experimental field. All physical and chemical characteristics of the oil including IR-spectra were determined. Operating conditions of castor oil introduction (temperature, solubility, concentra-tion, etc.) were determined. The received biofuel was tested at oil refinery and its bench tests with a positive effect were also carried out. Technical requirements and technological regulation (temporary) on manufacture of this biodiesel fuel were prepared.
