Abstract

Systems and methods are provided for forming specialty products from hydrotreated FCC fractions. Optionally, the hydrotreated FCC fractions used for forming the specialty products can further include a (hydrotreated) portion of a steam cracker tar fraction. The specialty products that can be formed from hydrotreated FCC fractions include, but are not limited to, carbon blacks, resins, and carbon fibers. A convenient method for forming the hydrotreated FCC fractions can be fixed bed hydrotreatment.

First claim

1 .- 11 . (canceled)

12 . A hydrotreated effluent comprising an 850° F.+ (454° C.+) fraction, the 850° F.+(454° C.+) fraction comprising
at least about 50 wt % of polycyclic hydrocarbonaceous compounds, at least about 5 wt % aromatics, a content of aromatics different from naphthenoaromatics of about 1.0 wt % or less, and a content of naphthenoaromatics having 4 or more aromatic rings being about 1000 wppm or less, based on a weight of the 850° F.+ (454° C.+) fraction,
wherein at least about 50 wt % of the polycyclic hydrocarbonaceous compounds comprise naphthenes based on a total weight of polycyclic hydrocarbonaceous compounds in the 850° F.+ (454° C.+) fraction.

13 . The hydrotreated effluent of claim 12 , wherein the 850° F.+ (454° C.+) fraction comprises at least about 60 wt % of polycyclic hydrocarbonaceous compounds.

14 . The hydrotreated effluent of claim 12 , wherein the 850° F.+ (454° C.+) fraction comprises at least about 50 wt % of polycyclic hydrocarbons.

15 . The hydrotreated effluent of claim 12 , wherein the content of aromatics different from naphthenoaromatics is about 1000 wppm or less.

16 . The hydrotreated effluent of claim 12 , wherein the hydrotreated effluent is formed by a process comprising hydrotreatment of a feed comprising at least 60 wt % of a catalytic slurry oil based on a weight of the feed, at least 10 wt % of a steam cracker tar based on a weight of the feed, or a combination thereof.

17 . A hydrotreated effluent fraction having a T10 boiling point of at least 510° C. and a T90 boiling point of 621° C. or less, the hydrotreated effluent fraction comprising, based on a weight of the hydrotreated effluent fraction, at least about 50 wt % of polycyclic hydrocarbonaceous compounds and about 0.1 wt % to about 5.0 wt % aromatics, a content of aromatics different from naphthenoaromatics of about 1.0 wt % or less, and a content of naphthenoaromatics having 4 or more aromatic rings of about 1000 wppm or less.

18 . The hydrotreated effluent fraction of claim 17 , wherein the hydrotreated effluent fraction comprises at least about 70 wt % polycyclic hydrocarbonaceous compounds based on the weight of the hydrotreated effluent fraction.

19 . The hydrotreated effluent fraction of claim 17 , wherein the hydrotreated effluent fraction comprises about 10 wt % of paraffins or less based on the weight of the hydrotreated effluent fraction.

20 . The hydrotreated effluent fraction of claim 12 , wherein the hydrotreated effluent fraction is formed by a process comprising hydrotreatment of a feed comprising at least 60 wt % of a catalytic slurry oil based on a weight of the feed, at least 10 wt % of a steam cracker tar based on a weight of the feed, or a combination thereof.
