Catalytic co-cracking of used cooking oil and plastic derived oils to produce circular chemicals and low carbon fuels

A process for producing circular chemicals and low-carbon fuels, the process comprising:

• producing a plastic derived oil stream from solid waste plastic;
• contacting the plastic derived oil stream with an acid gas removal catalyst disposed in an acid gas removal unit, where contacting the plastic derived oil stream with the acid gas removal catalyst removes acid gases from the plastic derived oil stream to produce a treated plastic derived oil stream, where the treated plastic derived oil stream has concentrations of halogen compounds, sulfur compounds, or both that are less than concentrations of the halogen compounds, sulfur compounds, or both in the plastic derived oil stream;
• passing the treated plastic derived oil stream and a used cooking oil stream to a fluidized catalytic cracking (FCC) system comprising an FCC reactor;
• and
• contacting the treated plastic derived oil stream and the used cooking oil stream with a cracking catalyst in the FCC reactor, where contacting the treated plastic derived oil stream and the used cooking oil stream with the cracking catalyst at a reaction temperature in the FCC reactor causes at least a portion of hydrocarbons from the treated plastic derived oil stream and the used cooking oil stream to undergo catalytic cracking reactions to produce an FCC effluent comprising circular chemicals, low-carbon fuels, or both.
