Atmospheric Pressure Reactor System
The atmospheric pressure reactor system is designed for testing the efficiency of various catalysts for the treatment of gas-phase pollutants. EMSL houses several quartz plug reactors designed to hold either extrudate or coated monolith catalysts. A gas inlet capable of mixing up to eight gases plus water is used to simulate the waste stream of interest. A temperature-programmable furnace controls the reactor temperature. After treatment, the gas is sampled by a Fourier transform infrared spectrometer, a gas chromatograph, and an oxides-of-nitrogen meter.
Individuals may use this instrumentation independently for their research, following applicable training.
