Embodiment approach

[0087] Additionally or alternatively, the invention may include one or more of the following embodiments.

Embodiment approach 1

[0089] A method of making a low sulfur marine fuel composition, the method comprising: hydrotreating a vacuum residue feed stream with hydrogen in the presence of a hydrotreating catalyst to produce a vacuum residue without substantially cracking the vacuum residue reducing sulfur to no more than about 1500 parts per million (ppm); and combining said hydrotreated vacuum residue with no more than about 10 volume percent of a first diesel boiling range hydrocarbon stream and no more than about 40 % by volume of a second diesel boiling range hydrocarbon stream blended wherein said vacuum residue feed stream has from about 1000 ppm to about 10000 ppm sulfur and said first diesel boiling range hydrocarbon stream has no more than about 20 ppm sulfur, and The second diesel boiling range hydrocarbon stream has no more than about 10 ppm sulfur.

Embodiment approach 2

[0091] The process of embodiment 1, wherein the vacuum resid feed stream has from about 6000 ppm to about 10000 ppm sulfur.

Abstract

This invention relates to low sulfur marine bunker fuel compositions and methods of making the same. The invention also relates to an uncracked, hydrotreated vacuum resid for use in making the low sulfur marine bunker fuel composition. Contrary to conventional marine / bunker fuel compositions, the low sulfur marine / bunker fuel composition uses mostly uncracked components, including a (cat feed) hydrotreated vacuum resid. The low sulfur marine / bunker fuel composition can also have reduced contents of residual components.

Description

technical field [0001] The present invention generally relates to methods of making marine fuels having a relatively low sulfur content and low sulfur fuel compositions made according to said methods. Background technique [0002] According to the MARPOL Revised Annex VI (Revised MARPOL Annex VI) promulgated by the International Maritime Organization (IMO), marine fuels will have stricter requirements on the upper limit of sulfur content worldwide. Additionally, individual countries and regions are beginning to limit sulfur levels used in ships in areas known as emission control areas, or ECAs. [0003] The fuel used in global shipping is usually bunker fuel for larger ships. Bunker fuels are advantageous because they are less expensive than other fuels; however, they typically consist of cracked and / or residual fuel and thus have higher sulfur levels. Distillates can often be used to meet lower sulfur specifications for marine vessels. However, distillate fuels are often...
