The FCC unit with addition of various inventories of the FP-DSN type sulfur transfer additive was tested in a commercial scale. The effect of the sulfur transfer additive was analyzed by investigating the indicators related with the regenerator flue gas composition, the dry gas composition before desulfurization, the LPG composition before desulfurization, the acid gas, and the yield of gasoline and diesel. The test results indicated that the sulfur was trans-ferred fi’om the feed stream into the dry gas, LPG and acid gas, and the sulfur transfer effect was obvious only when the inventory of sulfur transfer additive exceeded over 2.0% of total FCC catalyst inventory.
