Abstract
An upcycling system for converting plastic waste to value-added products such as sustainable aviation fuels (SAF) and process of using same. The system includes a plug-flow reactor with catalytic hydrocracking functionality. Halloysite catalysts can be used to convert the plastic waste, for example marine plastic waste, into SAFs such as n-alkanes, iso-alkanes, cycloalkanes, and aromatics.
Claims18
A system for upcycling plastic waste to produce sustainable aviation fuels (SAF), said system comprising:
- a plug-flow reactor (PFR) with catalytic hydrocracking functionality, wherein the PFR comprises a reactor tube comprising a catalytic material;
- a tubular furnace that can accommodate the reactor tube;
- a source of inert gas;
- a source of hydrogen gas;
- and
- a cold trap.
A process of upcycling plastic waste to produce sustainable aviation fuels (SAF), said process comprising:
- positioning a reactor tube of a plug-flow reactor (PFR) in a furnace, wherein the PFR comprises a catalytic material;
- removing air from the reactor tube using at least one inert gas;
- heating the reactor tube to a target temperature;
- introducing a feeding gas to the reactor tube once the target temperature is achieved;
- and
- collecting the SAFs through solvent extraction in a cold trap.
