Abstract
Biodiesel is synthesized from five different types of vegetable oils (sunflower, mustard, linseed, corn and camelina). The yields of the target product, the physicochemical and low-temperature properties of the obtained biodiesel fuels are determined. The effect of the additive on the low-temperature properties of biodiesel and its blends with petroleum diesel fuel is investigated. It is shown that the low-temperature additive for petroleum diesel fuels is ineffective for improving the low-temperature properties of biodiesel. It is established that the efficiency of the low-temperature additive decreases with an increase in the proportion of biodiesel in the blend with diesel fuel. The expediency of using biodiesel as a blend component of commercial diesel fuels is shown. Recommendations on the use of “biodiesel/diesel fuel/low-temperature additive” blends as commercial diesel fuels of the Summer grade and Off-Season grade according to GOST (State Standard) 305-2013 “Diesel fuel. Technical Specification” are developed.
