A microwave-induced, steam/Ar/O 2 , plasma "torch" was operated at atmospheric pressure to determine the feasibility of destroying volatile organic compounds (VOCs) of concern. The plasma process can be coupled with adsorbent technology by providing steam as the fluid carrier for desorbing the VOCs from an adsorbent. Hence, N 2 can be excluded by using a relatively inexpensive carrier gas, and thermal formation of oxides of nitrogen (NO x ) is avoided in the plasma.
