“…At depressant concentration of 0.05%, the diesel oil congelation temperature (pour point) was 16-18° and the maximum filterability temperature was 15-18°. Special attention should be paid to the latter characteristic because it was shown earlier [40] that not nearly all polyolefins affect it. The degraded products are effective only when the degradation conditions are maintained strictly.…”

Based on analysis of literature and patent information, the situation pertaining to fuel additives in the period 2006-2010 is reviewed. The major trends in additive development are shown and the main types of additives are characterized. It is noted that imported additives predominate in Russia, but thanks to indigenous developments that occurred over this period, the process of import substitution has begun, which may rid the fuel industry of its dependence on foreign supplies in the future. The demand of the Russian oil refining industry for additives required to produce fuels that meet the current standards is analyzed. The indigenous additive developments are described. Key words: additive, fuel, patenting of additives, wear-preventive additive, alkyl nitrate, depressant, disperser of paraffins, detergent additive.This article, being a continuation of reviews covering the period 1989-2005 [1], examines the situation with regard to fuel additives during 2006-2010. Increased attention to additives required for producing diesel fuels in keeping with Euro-3, 4, and 5 specifications, use of multifunctional additives and markers for creating brand grades of gasoline and diesel oils, and heightened interest in absorbers of volatile sulfur compounds in residual fuels are special features of this period.At the same time, any activity in the domain of obsolescent additives was discontinued almost completely.First of all, this relates to antiknock agents (dopes) based on compounds of metals, and not only of lead, but also of iron and manganese. Antismoke additives based on compounds of barium, calcium, and other metals are practically not used. They dropped out of use because of appearance of better-designed engines, for optimum (smooth) running of which use of detergent additives is enough. Note that additives, which are effective in carburettor engines, i.e., additives intended for injection-type engines, lost their importance conclusively along with these engines.
