Abstract: 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.

Abstract: A process for producing circular chemicals and low-carbon fuels includes producing a plastic derived oil stream from solid waste plastic, treating the plastic derived oil stream to produce a treated plastic derived oil stream having reduced concentrations of halogen compounds, sulfur compounds, or both, passing the treated plastic derived oil stream and a light crude oil stream to a cracking reactor, and contacting the treated plastic derived oil stream and the light crude oil stream with a cracking catalyst in the cracking reactor. Contacting of the treated plastic derived oil stream and the light crude oil stream with the cracking catalyst at a reaction temperature in the cracking reactor cracks at least a portion of hydrocarbons from the treated plastic derived oil stream and light crude oil stream to produce a cracking effluent comprising circular chemicals, low-carbon fuels, or both.

Abstract: Described herein are embodiments where crude oil and cooking oil may be co-processed in a method that includes catalytically cracking a hydrocarbon mixture to form hydrocarbon product. The hydrocarbon mixture may include from 1 wt. % to 20 wt. % of cooking oil and from 80 wt. % to 99 wt. % of crude oil having an API gravity of from 30° to 38°. The hydrocarbon product may include ethylene, propylene, and butenes.

Abstract: A process for producing circular chemicals and low-carbon fuels includes producing a plastic derived oil stream, contacting the plastic derived oil stream with an acid gas removal catalyst in an acid gas removal unit to remove halogen compounds, sulfur compounds, or both, 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. Contacting the treated plastic derived oil stream and the used cooking oil stream with the cracking catalyst at a reaction temperature 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 the circular chemicals, low-carbon fuels, or both.

Abstract: A process for upgrading plastic derived oil includes contacting the plastic derived oil with a mixed catalyst in a first reactor, where the mixed catalyst includes a decontamination catalyst and a cracking catalyst different from the decontamination catalyst. The first reactor reduces concentrations of halogen-containing compounds in the plastic derived oil. The process includes passing the first reactor effluent to a second reactor and contacting the first reactor effluent with the cracking catalyst to produce a second effluent comprising light olefins and naphtha range hydrocarbons. The process includes separating used mixed catalyst from the first reactor to produce a used decontamination catalyst and a second used cracking catalyst, and regenerating the decontamination catalyst and cracking catalyst in separate regenerators to reduce exposure of the cracking catalyst to halogen-containing compounds produced during regeneration of the used decontamination catalyst.

Abstract: A process for upgrading a plastic derived oil includes providing the plastic derived oil comprising hydrocarbons and greater than or equal to 100 ppmw halogen-containing compounds and contacting the plastic derived oil with an MMO catalyst in a first reactor at reaction conditions to remove halogens from the plastic derived oil to produce a first reactor effluent with less than 100 ppmw halogen-containing compounds. The process includes contacting the first reactor effluent with an adsorbent to produce a treated first reactor effluent, passing the treated first reactor effluent to a second reactor, and contacting the treated first reactor effluent with a cracking catalyst in the second reactor. Contacting with the cracking catalyst may cause hydrocarbons in the treated first reactor effluent to undergo catalytic cracking to produce a second reactor effluent comprising light olefins, naphtha range hydrocarbons, or combinations thereof.

Abstract: A method for determining a salt concentration of a hydrocarbon fluid using a conductivity sensor and a hydrocarbon testing solution includes forming the hydrocarbon testing solution. The electropolymerizable monomer is operable to form a resultant associated polymer at a peak potential of the electropolymerizable polymer. The method includes introducing the hydrocarbon testing solution into the conductivity sensor. The method includes inducing a range of potential across the hydrocarbon testing solution such that at least a portion of the electropolymerizable monomer polymerizes. The range of induced potential includes the peak potential of the electropolymerizable polymer. The method includes detecting a range of electrical current associated with the range of potential induced. The method also includes the step of determining the salt concentration of the hydrocarbon fluid using the range of potential induced and the range of electrical current detected.
