Production of carbon blacks and resins from hydrotreated catalytic slurry oil

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.

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.
