A reactor system includes a reactor that treats a lipid feedstock using a metal oxide catalyst to produce a treated stream comprising a bio-oil. The reactor system includes a catalyst zone in which the metal oxide catalyst reacts with the lipid feedstock to produce the treated stream.

A process for upgrading plastic derived oil includes contacting a plastic derived oil stream with a decontamination catalyst in a first reactor, separating a first reactor effluent from a used decontamination catalyst, passing the first reactor effluent to a second reactor downstream of the first reactor, contacting the first reactor effluent with a cracking catalyst in the second reactor, and separating a second reactor effluent from a used cracking catalyst. The cracking catalyst is different from the decontamination catalyst. The process further includes 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. Regenerating the used cracking catalyst separately reduces deactivation of the cracking catalyst by halogen-containing compounds produced during regeneration of the decontamination catalyst.
