Comparison of in-situ and ex-situ catalytic pyrolysis in a micro-reactor system

Aromatics vs. olefins from catalytic pyrolysis: in-situ and ex-situ catalytic pyrolysis were compared in a micro-reactor system. Ex-situ catalytic pyrolysis produced significantly more olefins while in-situ produced more aromatics. A dual catalytic cycle reaction mechanism is proposed based on the experimental results.
