Abstract: Systems and methods are provided for producing naphtha boiling range fractions having a reduced or minimized amount of sulfur and an increased and/or desirable octane rating and suitable for incorporation into a naphtha fuel product. A naphtha boiling range feed can be separated to form a lower boiling portion and a higher boiling portion. The lower boiling portion, containing a substantial amount of olefins, can be exposed to an acidic catalyst without the need for providing added hydrogen in the reaction environment. Additionally, during the exposure of the lower boiling portion to the acidic catalyst, a stream of light olefins (such as C2-C4 olefins) can be introduced into the reaction environment. Adding such light olefins can enhance the C5+ yield and/or improve the removal of sulfur from thiophene and methyl-thiophene compounds in the naphtha feed.

Abstract: Systems and methods are provided for upgrading blends of catalytic slurry oil and steam cracker tar to form fuel and/or fuel blending products. The steam cracker tar can optionally correspond to a fluxed steam cracker tar that includes steam cracker gas oil and/or another type of gas oil or other diluent. It has been unexpectedly discovered that blends of catalytic slurry oil and steam cracker tar can be hydroprocessed under fixed bed conditions while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst and/or while reducing or minimizing plugging of the fixed bed, as would be conventionally expected during fixed bed processing of a feed containing a substantial portion of steam cracker tar. Additionally or alternately, it has been unexpectedly discovered that formation of coke fines within steam cracker tar can be reduced or minimized by blending steam cracker tar with catalytic slurry oil. This can facilitate fixed bed processing of the steam cracker tar, as after removal of particles the blend of catalytic slurry oil and steam cracker tar can maintain a reduced or minimized level of coke fines and/or other particles.
