Abstract
The removal of sulfur-containing odorants from natural gas has been investigated by using sorption. The CuD/ZnO/Al 2 O 3 sorbents were prepared by a coprecipitation/aging method. A reduced sorbent, namely, Cu/ ZnO/Al 2 O 3 , has a sorption capacity of 0.5 mmol/g at 250 °C when the sodium content is kept below 0.027 wt %. The high sorption capacity of the sorbent is due to the better dispersion of nanocrystalline copper metal particles in a zinc oxide matrix as confirmed by X-ray diffraction analysis. The Brunauer-Emmett-Teller surface area of calcined material (Cu/ZnO/Al 2 O 3 ) increased systematically from 18.38 to 104.26 m 2 /g with the lowering of the residual Na concentration. The temperature-programmed reduction study revealed that high incorporation of Na made the reduction of the CuO phase difficult in unwashed sorbent. However, as the Na content is lowered below 0.027 wt %, the reduction of CuO particles occurred at much lower temperatures because of the strong interaction of nanosized CuO with ZnO particles.
