Abstract: Disclosed are processes and systems for oxidizing cycloalkylbenzene such as cyclohexylbenzene to make an oxygenate such as a hydroperoxide thereof. A liquid distributor having multiple liquid ingress ports is used for supplying a cycloalkylbenzene-containing liquid into an oxidation reactor in the form of liquid streams forming part of the reaction medium. A gas distributor distributing an O2-containing gas into the reaction medium in the form of gas streams is preferably located below the liquid distributor. Preferably the gas bubbles upwards in the reaction medium. The agitation and mixing provided by the liquid streams, gas streams/bubbles result in sufficient homogeneity of cycloalkylbenzene concentration, cycloalkylbenzene hydroperoxide concentration, dissolved oxygen concentration, and temperature in the liquid phase.

Abstract: In a process for producing phenol, a mixture of cyclohexylbenzene with from 10 to 90 wt % of a solvent is contacted with oxygen in the presence of a catalyst and under conditions effective to oxidize at least a portion of the cyclohexylbenzene to cyclohexylbenzene hydroperoxide. The catalyst comprises a cyclic imide having an imide group of formula (I): wherein X represents an oxygen atom, a hydroxyl group, or an acyloxy group. At least a portion of the oxygen is dissolved in the mixture and the liquid phase molar ratio of cyclohexylbenzene to oxygen dissolved in the mixture is less than or equal to 20,000:1.

Abstract: Systems and methods are provided for integration of a reactor for polyolefin pyrolysis with the effluent processing train for a steam cracker. The polyolefins can correspond to, for example, polyolefins in plastic waste. Integrating a process for polyolefin pyrolysis with a steam cracker processing train can allow a mixture of polymers to be converted to monomer units while reducing or minimizing costs and/or equipment footprint. This can allow for direct conversion of polyolefins to the light olefin monomers in high yield while significantly lowering capital and energy usage due to integration with a steam cracking process train. The integration can be enabled in part by selecting feeds with appropriate mixtures of various polymer types and/or by limiting the volume of the plastic waste pyrolysis product relative to the volume from the steam cracker(s) in the steam cracking process train. By selecting plastic waste and/or other polyolefin sources with an appropriate mixture of polyolefins as the feedstock, the resulting polyolefin pyrolysis product can be separated in a steam cracking process train to produce separate fractions for various polymer grade small olefin products.

Abstract: Systems and methods are provided for reducing or minimizing the chloride content of products generated during co-processing of a plastic feedstock (such as plastic waste) in a refinery process. The reduction in chloride is achieved by mixing the plastic feedstock with one or more additional feedstocks for co-processing in a mixing and/or holding vessel that is maintained at a dechlorination temperature that allows for decomposition of chlorine from the plastic feedstock to form HCl, while reducing or minimizing other conversion of the plastic feedstock and/or the additional feedstock. A purge gas can be passed through the mixing/holding vessel to remove the evolved HCl from the vessel. Because the dechlorination temperature is selected to reduce or minimize conversion of the feedstocks in the mixture, the amount of carbon-containing products that are removed with the purge gas can be reduced or minimized. The dechlorinated mixture of plastic feedstock and additional feedstock(s) can then be processed in a convenient refinery process, such as a thermal cracking process (e.g., coking, visbreaking, other types of pyrolysis) or a catalytic conversion process (e.g., fluid catalytic cracking).

Abstract: Systems and methods are provided for co-processing of plastic waste in a coking environment or other thermal conversion environment. The co-processing of plastic waste in a coking environment can be performed by performing four types of processes on the plastic waste. The plastic waste can be conditioned by classifying and sizing of the plastic waste to improve the suitability of the plastic waste for co-processing. The conditioned plastic waste particles can be entrained and/or dissolved into a solvent and/or the base feed. The solution and/or slurry of plastic waste can be passed into a coking environment, such as a fluidized coking environment or a delayed coking environment. The plastic waste can then be co-processed in the coking environment to generate liquid product.
