| Abstract: | The adsorption capacity of fine rubber particle media (FRPM) derived from discarded vehicle tires and the consumer wasted rubber sources was evaluated for hydrogen sulfide treatment. H2S breakthrough tests were performed at various zinc contents, temperatures, and packing quantities. High zinc concentrations increased the adsorption capacity of FRPM significantly. H2S removal by FRPM was optimized at a packing quantity of 75 % of the column volume, and the adsorption capacity increased with reactor temperature within the range of 20–85 °C. The regeneration of ZnCl2 solution was reliable for increasing regeneration capacity of the FRPM-adsorbed H2S. FRPM seems to be an attractive alternative of H2S adsorbents in terms of cost effectiveness compared to traditional materials. |
