Abstract
The adsorption of hydrogen sulfide (H2S) from the gas stream in a fixed-bed reactor has been investigated using zinc oxide (10–30 wt% loading) impregnated on Na-A zeolite prepared from local kaolin. The adsorbents obtained were characterized by XRF, XRD, FTIR, nitrogen adsorption and SEM. Reductions of micropore surface area and micropore volume of Na-A zeolite were observed after modification with zinc oxide. H2S adsorption capacity was the highest, 15.75 mg S/g sorbent, when 20 wt% ZnO was loaded on Na-A zeolite. Reduction in adsorption capacity was observed when wt% ZnO increased above 20 wt%.
