Systems and integrated methods are disclosed for processing aromatic complex bottoms into high value products. The system includes an adsorption column, the adsorption column in fluid communication with an aromatics complex and operable to receive and remove polyaromatics from an aromatic bottoms stream. The adsorption column producing a cleaned aromatic bottoms stream with reduced polyaromatic content and a reject stream including the removed polyaromatics. In some embodiments, the reject stream is recycled for further processing, passed to a coke production unit to produce high quality coke, or both.

Favorable isomerization conditions for producing normal paraffins can produce olefins. The process for separating normal paraffins from non-normal paraffins by adsorption has a limit on olefin concentration, so the olefins must be removed. We propose to remove olefins from the isomerization effluent stream that is recycled to the adsorption separation process.

Disclosed is a method for producing low carbon olefins and/or aromatics from feedstock comprising naphtha. The method can include the following steps: a) feeding feedstock comprising naphtha into a fast fluidized bed reactor; b) contacting the feedstock with a catalyst under conditions to produce a gas product and spent catalyst; c) separating the gas product to produce a stream comprising primarily one or more low carbon olefins and/or one or more aromatics; d) transporting the spent catalyst to a regenerator; e) regenerating the spent catalyst in the regenerator to form regenerated catalyst; and f) returning the regenerated catalyst to the fast fluidized bed reactor.

A method for producing an olefin and a monocyclic aromatic hydrocarbon of the present invention includes a dicyclopentadiene removal treatment step of removing dicyclopentadienes having a dicyclopentadiene skeleton from a feedstock oil which is a thermally-cracked heavy oil obtained from an apparatus for producing ethylene and which has a 90 volume % distillate temperature, as a distillation characteristic, of 390° C. or lower; and a cracking and reforming reaction step of obtaining a product containing an olefin and a monocyclic aromatic hydrocarbon by bringing the feedstock oil having a content of dicyclopentadienes adjusted to 10% by weight or less by treating a part or all of the feedstock oil through the dicyclopentadiene removal step into contact with a catalyst and reacting the feedstock oil.
