Abstract
A method for removing at least one contaminant selected from the group consisting of H S and CO from contaminating streams, including the steps of providing an above ground stream comprising hydrocarbon containing the at least one contaminant, and positioning metal-containing nanoparticles having a particle size of less than or equal to about 100 nm in the stream, the metal-containing nanoparticles being selected from the group consisting of metal oxides, metal hydroxides and combinations thereof, whereby the nanoparticles adsorb the contaminants from the stream.
