Catalytic pyrolysis of delaminated polyolefin films for sustainable aviation fuel production
A novel process utilizing catalytic pyrolysis of dealuminated polyolefin films with composite catalysts in a microwave reactor to produce sustainable aviation fuels. This method reduces landfill waste and fossil fuel dependency, supporting a circular low-carbon economy.
Overview
This innovative process focuses on converting waste polyolefin films into sustainable aviation fuels (SAF) through catalytic pyrolysis. By employing composite catalysts such as HZSM-5/MCM-41, H-Beta/Al₂O₃, and SAPO-11/SBA-15, the process enhances the cracking of polymers into C8–16 olefins, suitable for SAF. This approach not only addresses waste management issues but also contributes significantly to reducing the aviation industry's carbon footprint, achieving up to 60% yield of SAF range olefins.
Technical specifications
- Catalytic Pyrolysis: Utilizes composite catalysts to synergize strong acidity and mesoporosity, enhancing cracking efficiency and reducing energy demands.
- Microwave Reactor: A continuous microwave reactor is employed to achieve volumetric heating, optimizing the conversion of polymers to hydrocarbons.
- Dealumination Process: Hydrothermal dealumination prevents catalyst deactivation, maintaining high fuel production efficiency.
- Optimization Parameters: Includes microwave power level, pyrolysis atmosphere, residence time, catalyst-to-feed ratio, and particle size.
- SAF Characterization: Fuel production will be assessed against ASTM D7566 standards for aviation use.
Technology readiness level
Currently at Technology Readiness Level 3, this project is in the experimental proof of concept stage. The upcoming 12-month research plan includes retrofitting the reactor, catalyst development, and process optimization, with trials expected to produce results by the 7th month through to the 11th month.
