When the Pt/γ-Al2O3 catalyst was prepared by impregnation method,the modification of the carrier and the competitive adsorbents in carrier could influence the dispersion of catalyst.Domestic and foreign researches have showed that the improvement in the dispersity of catalyst active components could be achieved by the modification of the carrier,improve the reaction conditions and the reducing agents.
