POUR-DEPRESSANT ADDITIVES FOR DIESEL FUELS

Straight-chain alkanes, when added to diesel fuel in amounts of 5% or more, harm the low-temperature characteristics of the fuel. The presence of these hydrocarbons produce sharp increases in the cloud point, filterability temperature, and solid point of diesel fuels, and it is found that these three temperatures tend to converge when the n-alkanes are present. Results of an experimental study are presented which show that the most effective pour-depressant additives are those containing such structural elements as an ester group in an aliphatic chain with olefinic bonds, the total mol. wt of such additives must be several times the mol. wt of the diesel fuel. A given pour-depressant additive manifests identical effectiveness in fuels of a given hydrocarbon composition, including fuels with similar contents of n-alkanes.
