Abstract
A method for removing at least one contaminant selected from the group consisting of H2S and CO2 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.
