1. A method for removing sulfur contaminants from a gas stream comprising:
contacting a gas stream comprising hydrocarbons and sulfur contaminants with a modified nanocomposite adsorbent, wherein the modified nanocomposite adsorbent comprises waste bauxite residue doped with zinc oxide nanoparticles,
wherein the contacting of the gas stream with the modified nanocomposite adsorbent reduces an amount of sulfur contaminants in the gas stream.
