Abstract: According to the low sulfur property of the catalytic gasoline, the adsorbent desulfurization principle was analyzed. Measures were implemented, such as controlling the water content in FCC gasoline and process, carbon on adsorbents, sulfur content difference between adsorbent and unreduced adsorbent, optimizing process parameters, reforming heat removal system, to achieve the purpose of saving the consumption of adsorbent. The actual consumption of adsorbent of 1.8 Mt/a S-Zorb unit after optimizing the parameters is 12 tons/year, far lower than the design value（60 t/a）. The operation cost is effectively reduced and considerable economic benefits are achieved.

Key words: gasoline refining, adsorbent, measure, heat removal system
