METHOD FOR CARRYING OUT A CHEMICAL REACTION IN AN UPFLOW REACTOR
The present invention relates to a method for carrying out a catalysed chemical reaction using one or more liquid reactants, preferably acetone and phenol to form bisphenol A, in an upflow reactor comprising feeding at least a portion of said reactants to a bottom section of the reactor positioned below a flow distributor plate, passing said portion through the flow distributor plate, passing said portion through a layer of inert particles positioned above and preferably in contact with said flow distributor plate, passing said portion through a catalyst layer comprising a particulate catalyst, said catalyst layer being positioned above and in contact with said layer of inert particles, wherein the reactants react to form a product stream, collecting said product stream via collecting means positioned above said catalyst layer. The invention also relates to a reactor assembly. The catalyst is a core-shell catalyst which is manufactured by graft polymerizing aromatic vinyl compounds onto the hydroxylated and functionalized core particles, followed by sulfonation.

PROCESS FOR CONVERSION OF WASTE PLASTICS INTO CHEMICALS
The present invention relates to a process for the conversion of plastics to chemicals comprising in this order the steps of: (i) providing a plastics stream (A) comprising polyvinyl chloride (PVC); (ii) supplying the plastics stream (A) and a solvent (S) to a reactor vessel (1); (iii) subjecting the plastics in the reactor vessel to a temperature of ≥250° C. to <350, preferably of ≥275° C. and ≤325° C., preferably for a period of 5-30 minutes, under applying a vacuum, preferably of ≤200 mbar, or using an inert gas sweep, and evacuating the generated hydrogen chloride (B) from the vessel, wherein the PVC is partially dechlorinated to form a plastics stream (C) comprising partially unsaturated PVC; (iv) removing the plastics stream (C) comprising partially unsaturated PVC from the reaction vessel; (v) separating in a separation system (2) at least a part of the partially unsaturated PVC from the plastics stream to form a dechlorinated plastics stream (D) comprising the solvent; (vi) supplying the stream (D) comprising the solvent and the dechlorinated plastics to a solvent recovery system to recover the solvent and obtain a dechlorinated plastics stream (E); (vii) mixing the stream (E) with a recycle stream from a coker (K) to form a pre-feed stream (F); (viii) mixing the stream (F) with a coker feed (G) to product a feed stream (H) that meets the chlorine specifications for a coker unit (4); and (ix) subjecting the coker unit (4) to such conditions to obtain a liquid coker stream (I) and a solid coke product (L). Such process allows for the conversion of plastic compositions comprising PVC into chemical products that are suitable for renewed use as raw materials in for example the production of high-quality polymer materials, thereby contributing to improvement of circular use of plastic materials.

Systems and methods for upgrading a hydrocarbon stream to a lower boiling point hydrocarbon feed material are disclosed. The system includes a feeding device to transport a hydrocarbon stream that includes an alternative feedstock. The hydrocarbon stream is partially cracked in a first cracking unit producing a lower boiling point hydrocarbon feed material, a catalyst rich heavy hydrocarbon stream, and coke. A slurry settler receives the catalyst rich heavy hydrocarbon stream and coke and separates the catalyst from the catalyst rich heavy hydrocarbon stream thereby defining a catalyst rich stream and a heavy hydrocarbon stream. A coking vessel receives the heavy hydrocarbon stream and coke and separates the heavy hydrocarbons from the coke thereby defining a heavy hydrocarbon stream. Finally, a second cracking unit that receives the lower boiling point feed material from the first cracking unit and produces olefins and aromatics.
