Abstract
An upcycling system for converting plastic waste to value-added aromatic products and process of using same. The system includes a plug-flow reactor with catalytic hydrocracking functionality. Zeolite catalysts can be used to convert the plastic waste, for example marine plastic waste, into aromatic products such as benzene, toluene and/or xylene.
Claims20
A system for upcycling plastic waste to produce aromatic compounds, said system comprising:
- a plug-flow reactor (PFR) with catalytic hydrocracking functionality, wherein the PFR comprises a reactor tube comprising a catalytic material;
- a furnace;
- a source of inert gas;
- a source of hydrogen gas;
- and
- a cold trap.
3 more elements
A process of upcycling plastic waste to produce aromatic compounds, said process comprising:
- introducing the plastic waste to a plug-flow reactor (PFR) reactor tube, wherein the reactor tube comprises a catalytic material;
- removing air from the reactor tube using at least one inert gas;
- heating the reactor tube and the plastic waste contained therein to a target temperature;
- introducing a feeding gas to the reactor tube once the target temperature is achieved;
- and
- collecting the produced aromatic compounds through solvent extraction in a cold trap.
