Abstract
Catalytic pyrolysis has been proposed as a possible process for the recovery of caprolactam from waste nylon-6. Promising process conditions, i.e. catalyst and temperature were identified using a micro-scale reactor/molecular-beam mass-spectrometer system. At 330–360°C, in the presence of α-alumina supported KOH, the reaction proceeded at a high rate and selectivity. Only a few minutes were needed to complete the nylon-6 depolymerization with a caprolactam yield of 85%. These results were confirmed in a bench-scale fluidized bed reactor system.
