Abstract
Provided is a hydrocarbon tar. The tar has 75 wt % or more of aromatics of 10 carbons to 75 carbons based on the total weight of the tar. The aromatics exhibit 40% to 80% aromaticity. The tar has a boiling point of from 300° F. to 1350° F. There is also a fuel oil composition having the tar therein. There are also processes for making the hydrocarbon tar.
Claims24
A hydrocarbon tar, comprising:
- 75 wt % or more of aromatics of 10 carbons to 75 carbons based on the total weight of the tar, wherein the tar is of 40% to 80% aromaticity and a boiling point of from 300° F. to 1350° F.
A fuel oil composition, comprising:
- a blend of 10 wt % to 100 wt % of aromatics of 10 carbons to 75 carbons and 90 wt % to 0 wt % of non-aromatic hydrocarbons of 10 or more carbons, wherein the aromatics exhibit 40% to 80% aromaticity, wherein the aromatics and the non-aromatic hydrocarbons are 95 wt % or more of the total weight of the composition.
A process for making a hydrogenated tar, comprising:
- a) refining a first stream of hydrocarbons in a vacuum or atmospheric distillation tower to produce a tower stream;
- b) cracking the tower stream in a steam cracker to produce a cracker stream of 75 wt % or more of aromatics of 10 carbons to 75 carbons and 60% to 80% aromaticity based on the total weight of the tower stream;
- and
- c) partially hydrogenating the cracker stream to form a hydrocarbon tar of an aromaticity of 40% to 80% and a boiling point of from 300° F. to 1350° F.
1 more element
A process for making a hydrocarbon tar, comprising:
- a) refining a crude oil or a natural gas liquid stream to produce an aromatic stream of at 75 wt % or more of aromatics of 10 carbons to 75 carbons and 60% to 80% aromaticity based on the total weight of the composition;
- b) partially hydrogenating the aromatic stream to form a hydrocarbon tar of an aromaticity of 40% to 80% and a boiling point of from 300° F. to 1350° F.
