INFLUENCE OF THERMAL TREATMENT ON CATALYTIC BEHAVIOR OF Cu/13X CATALYST IN CWPO OF PHENOL AQUEOUS SOLUTIONS

Influence of postsynthesis thermal treatment of copper bearing 13X zeolite on its activity and stability in the catalytic wet peroxide oxidation of aqueous phenol solutions was investigated. The catalytic tests were carried out in a stainless steel Parr reactor in batch operation mode at 353 K. The experimental results showed that total degradation of phenol can be achieved under mild operating conditions. The postsynthesis thermal treatment resulted in more stable catalyst in respect to stability of both catalysts' active metal component (copper) and support while the activity of catalysts in terms of TOC conversion remained unaltered.
