The Use of Biodiesel as a Blend Component of Commercial Diesel Fuels

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) 303-2013 "Diesel fuel. Technical Specifications" are developed.
