Description

The objectives of this study were to compare the commercially available sorbent materials for removing typical indoor volatile organic compounds (VOCs) and to obtain data and experience that are useful to the development of a standard test method for sorbent media evaluation. A multichannel stainless steel air-cleaning technology testing system (ACTTS) was developed and used to test eleven pellet/granular-type sorbent media representing different base materials (coal, bituminous coal, coconut, bamboo wood, and activated aluminas with potassium permanganate and activated carbon) for seven VOCs. Tests were conducted for VOCs including hexane, decane, toluene, tetrachloroethylene, 2-butanone, isobutanol, and D-limonene. Concentrations versus time during sorption and desorption periods were obtained. The sorbent media’s performances were evaluated in terms of removal efficiency and removal capacity per unit of sorbent weight as a function of time, the 50% breakthrough time, and the half-life time removal capacity. In addition, repeatability of the test and the effect of flow rate on the test results were also investigated. The challenges of developing a standard test method and procedure for performance evaluation of pellet/granular-type sorbent media based on the experiences gained from the study are also discussed briefly in this paper.
