ABSTRACT:
A low smoke point (e.g., 29) jet fuel can be used to produce a higher smoke point fuel (e.g., 40+) by blending with an additional more highly paraffinic fuel (e.g., high in C.sub.10 -C.sub.12 normal paraffins) boiling mainly within the fuel oil boiling range (e.g., 10% point of at least 270.degree.F and 90% point less than 540.degree.F). A preferred group of paraffinic fuels comprises n-decane, n-dodecane and mixtures thereof. Hydrogenated butylene and/or propylene polymers (e.g., trimer, tetramer), preferably hydrogenated propylene "tetramer" boiling mainly above 350.degree.F (e.g., 10% point of 360.degree.F), can also be used as additional components. The preferred 29+ smoke point fuel for blending with n-dodecane is obtained by a two stage hydrogenation of a paraffinic straight run kerosene having an API gravity of at least 42, and containing 12 to 16 weight percent aromatics and at least 45 weight percent paraffins. The blended fuel also can have a desirably low freeze point.
