Catalytic thermal decomposition of polyamides and polyurethanes mixed with acidic zeolites

► Catalytic pyrolysis and conversion of polymers pyrolysate lead to different products. ► From 1:1 mixture of Y zeolite-polyamide dinitrile or dehydrated cyclic monomer form. ► Catalytic pyrolysis of MDI segments of PUR leads to aniline and p-toluidine. ► Excess of catalyst convert all the volatile pyrolysis products mainly to aromatics.
