Description:
The processing of iron oxide nanoparticles derived from spray flame synthesis for specific adsorption applications is described. After the as-prepared particles proved the ability for H 2 S removal in pure gas treatment, two different nanoparticle-based composite materials were prepared. While impregnation of activated carbon with the as-prepared nanoparticles showed the expected increase in H 2 S adsorption capacities, a significant enhancement in desulfurization performance was observed for a novel iron oxide nanoparticle composite material. H 2 S adsorption was tested in fixed-bed breakthrough curve measurements. The H 2 S removal efficiency of the novel material under ambient conditions indicates highly promising properties for potential use in industrial and air pollution control applications. A promising approach to develop new adsorbents is the usage of nanoscale materials. An innovative adsorbent for desulfurization application was prepared by synthesizing a carbonaceous, porous structure with embedded nanoparticles, creating a Fe x O y nanoparticle/polystyrene composite. The obtained adsorbent provided a significantly higher capacity for H 2 S adsorption at room temperature.
