- •
Continuous pyrolysis of PS was performed in a CSBR without operational problems.
- •
Styrene recovery is highly dependent on pyrolysis temperature and gas flow rate.
- •
Operating conditions greatly influence PS depolymerisation mechanism.
- •
At 500 °C and u/ums = 2 a maximum styrene yield of 70.5 wt% was obtained.
- •
By-products are suitable for recirculation or valorisation as raw materials.
