Abstract
Official abstract text for this publication.
The present invention provides a method for producing a gas oil composition which contains a cracked base gas oil with a poor oxidation stability but is enhanced in oxidation stability resulting in less sludge or deposit formation. The method comprises blending 0.5 to 15 percent by volume of a cracked reformed base oil having a total aromatic content of 80 to 100 percent by volume, a bicyclic aromatic content of 40 to 95 percent by volume, a 10 vol. % distillation temperature of 160 to 250° C. and a 90 vol. % distillation temperature of 260 to 330° C. and 10 to 70 percent by volume of a cracked base gas oil thereby producing a gas oil composition with an induction period of 60 minutes or longer, a sulfur content of 10 ppm by mass or less and a cetane number of 45 or greater.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a gas oil composition with an induction period of 60 minutes or longer, a sulfur content of 10 ppm by mass or less and a cetane number of 45 or greater, comprising blending 0.5 to 15 percent by volume of a cracked reformed base oil having the following properties (1) to (4) and 10 to 70 percent by volume of a cracked base gas oil: (1) a total aromatic content of 80 to 100 percent by volume; (2) a bicyclic aromatic content of 40…
