The possibility of using liquid biofuels with additives of vegetable oils and fatty acid esters

The results of multi-criteria analysis obtained on the basis of experimental data in the process of studying the main properties and characteristics of thermal conversion of alternative liquid fuels are presented. Kerosene was used as the basic hydrocarbon component. Bioadditives are represented by vegetable oils (rapeseed oil, tall oil, camelina oil, and waste culinary oil) and methyl esters of fatty acids obtained during the processing of these oils. The combustion characteristics of fuel compositions were experimentally determined: ignition delay times, threshold temperatures of combustion initiation, burnout duration, and concentrations of the main gas emissions. Promising fuel compositions are identified taking into account the main energy and environmental indicators. The possibilities of using compositions with methyl esters of fatty acids to reduce specific anthropogenic emissions in the composition of combustion products are substantiated.
