In order to attain more excellent sorbent,experiments were carried out in a laboratory fixed-bed setup at 700 K and space velocity of 1000 h-1.The effect of additive on performance in desulfurization was investigated with iron trioxide hydrate,cupric oxide as main active component.The results illustrated that the outlet concentration of COS for sorbent added kaolin can be below 0.2×10-6 before breakthrough compared with other sorbents and sulfur capacity reach 24.3 g·S/100 g.The mechanical strength attain 81.7 N/cm and bulk density of attain 0.717 g/cm3.
