Abstract
Low sulfur marine fuel compositions and methods for making the same are provided. The compositions exhibit a sulfur content of at most 0.50 wt. %, a solvent power of at least 0.30, and a P-value of at least 1.15.
Claims12
A marine fuel oil composition having a sulfur content of at most 0.50 wt. %, a solvent power (Po) of at least 0.30, and a P-value of at least 1.15;
- the marine fuel oil composition further comprising:
- (a) 15 wt. % or less of a residuum hydrocarbon component comprising at least one of solvent deasphalted residue, deasphalted oils, atmospheric tower bottoms, and vacuum tower bottoms;
- (b) 15 to 65 wt. % of a gas oil component comprising at least one of non-hydrotreated vacuum gas oil, hydrotreated vacuum gas oil, and straight-run gas oil;
- (c) 15 to 85 wt. % of an aromatic feedstock component comprising at least one of ethylene cracker bottoms, slurry oil, heavy cycle oil, and light cycle oil;
- and
- (d) 30 wt. % or less of a hydroprocessed hydrocarbon component comprising at least one of waxy light neutral hydrocrackate, diesel, and jet fuel.
