Degradation of phenol by a catalytic ozonation

Screening on the catalytic ozonation of phenol over zeolite-based catalyst i.e Beta and ZSM-5 was investigated under room temperature condition using a semi continuous system. The degree of degradation of 100ppm of phenol was measured on the treated samples. The results showed that the performance o...

The degree of degradation of 100ppm of phenol was measured on the treated samples. The results showed that the performance of Beta was better than ZSM-5 with the degradation of phenol of 67.4 and 49.0%, respectively after 90 minutes of reaction time.
