Abstract: A catalyst for oxidizing carbon monoxide (CO), volatile organic compounds (VOCs), and methyl bromide (CH3Br) is provided. The catalyst comprises a first base metal catalyst supported on an oxygen donating support that is substantially free of alumina, and at least one second base metal catalyst. Also provided is a method for treating the waste stream from a purified terephthalic acid (PTA) process, the method comprising contacting a waste stream containing carbon monoxide (CO), volatile organic compounds (VOCs), and methyl bromide with a catalyst comprising a first base metal catalyst supported on an oxygen donating support that is substantially free of alumina, and at least one second base metal catalyst.
