Binary Adsorption of n-Butane or Toluene and Water Vapor
To clean the air in cars of noxious gases by adsorption, predominantly activated carbon is used. The height of the activated carbon layer is especially small in cabin air filtration. As test substances for adsorptive filters in cabin air filtration, toluene and n-butane are prescribed in several engineering standards, e.g., ISO TS 11155-2. In the study presented, the differences in binary adsorption between toluene or n-butane and water vapor are investigated with emphasis on adsorption equilibrium and kinetics at temperatures between 15 degrees C and 33 degrees C, and relative humidity varying between 0 % and 90 %. The range of input concentrations is from 2 ppm(V) up to 80 ppm(V).
