Adsorption of ultra-low concentrations of ethylene at low temperatures. Procedure for eliminating traces of ethylene in air currents that can comprise the steps: - A first step where the gaseous mixture is introduced into a reactor that comprises at least one bed containing a material that can be selected from a zeolite, amorphous silica, magnesium sulfate, sodium hydroxide, potassium hydroxide, potassium sulfate, calcium sulfate, potassium carbonate, and combinations thereof; - A second step in which the effluent from the first step is fed into another reactor that comprises at least one catalyst that comprises at least one zeolite exchanged with at least one metal ion that can be preferably selected from Ag , Pd, Cu, Pt, Au, Ru, Sn, Ce, Cu, Ni, Mn, Mo and combinations thereof; and - Recovery of the outlet gas stream. |
