Dual reactor system with dual catalyst regeneration for upgrading plastic derived oil to hydrocarbon intermediates

A process for upgrading plastic derived oil to produce hydrocarbon intermediates and fuel components, the process comprising:

• contacting a plastic derived oil stream with a decontamination catalyst in a first reactor, where:
• the decontamination catalyst comprises a plurality of metal oxides, where each of the metal oxides are randomly distributed throughout the decontamination catalyst, and where the plurality of the metal oxides are selected from the group consisting of Fe2O3, ZrO2, CeO2, Al2O3, TiO2, CaO, Na2O, MgO, and combinations thereof;
• and
• the first reactor is a fluidized bed reactor, and the contacting the plastic derived oil stream with the decontamination catalyst at reaction conditions produces used decontamination catalyst and a first reactor effluent having a reduced concentration of halogen-containing compounds compared to the plastic derived oil stream;
• separating the first reactor effluent from the used decontamination catalyst;
• passing at least a portion of the first reactor effluent to a second reactor disposed downstream of the first reactor;
• contacting the at least a portion of the first reactor effluent with a cracking catalyst in the second reactor, where:
• the cracking catalyst is different from the decontamination catalyst, the second reactor is a fluidized bed reactor, and the contacting of the at least a portion of the first reactor effluent with the cracking catalyst at reaction conditions in the second reactor catalytically cracks the portion of the first reactor effluent to produce used cracking catalyst and a second reactor effluent comprising light olefins, naphtha range hydrocarbons, or combinations thereof;
• separating the second reactor effluent from the used cracking catalyst;
• regenerating the used decontamination catalyst in a decontamination catalyst regenerator to produce regenerated decontamination catalyst;
• and
• regenerating the used cracking catalyst in a cracking catalyst regenerator separate from the decontamination catalyst regenerator to produce regenerated cracking catalyst, where regenerating the used cracking catalyst in the cracking catalyst regenerator reduces exposure of the regenerated cracking catalyst to hydrogen halides and halogen compounds produced in the first reactor or during regeneration of the used decontamination catalyst.
