Phenolic compounds are one of the components that are widely used or produced in chemical industries such as oil and gas, pesticides, pharmaceuticals, textiles, and many others. According to the United States Environmental Protection Agency (EPA), phenol is a dangerous pollutant and must be avoided. In Indonesia, the permissible limit for phenol content in waters is less than 1 mg / L. There are several methods that can be used to degrade phenol. However, the method that was chosen is catalytic ozonation using a heterogeneous catalyst, zeolites, because it can degrade phenol efficiently. This research is done using zeolite catalyst with FAU framework and ANA zeolite. Few treatments were done to the catalyst that is used which consists of calcination, protonation, and calcination, and without treatments. Catalyst activity using the catalytic ozonation method for phenol waste degradation is tested for 60 minutes using 1L of ozone/minute at every given run. The Phenol sample that is used has an initial concentration of 200 ppm and the variance that is done to the test is ozone flowrate and Si/Al ratio of zeolite. Samples of concentrated phenol are taken every 10 minutes and measured using UV-Vis technology. The purpose of this research is to synthesize, characterize and evaluate the performance of zeolite with FAU framework as a catalyst to degrade phenol with the ultrafast synthesis method. The result of this research shows that zeolite catalyst with FAU framework Si/Al 20 yields phenol waste degradation efficiencies at 93.03%, FAU zeolite Si/Al 38 yield an efficiency of 86.53%, and no catalyst used yields an efficiency of 62.54%. Then, results that are obtained using FAU Si/Al 20 catalyst give a higher phenol degradation level compared to FAU Si/Al 38 catalyst. The catalyst without treatment yields a better phenol concentration and rate compared to other treatments. Lastly, the run using no catalyst and FAU Si/Al 38 catalyst, 90% ozone concentration gives a better phenol degradation rate and efficiency compared to 60% and 30% ozone concentration. Whereas on the run using FAU Si/Al 20 catalyst, 60% ozone concentration gives a better phenol degradation rate and efficiency.
