Abstract: The commercial results of FCCG selective hydrodesulfurization catalyst regulation technology（RSAT）based on the RSDS-II process in Qingdao refinery show that the sulfur content of FCC gasoline can be dropped to less than 50μg/g, meeting the standard of national phase IV gasoline, or less than 10μg/g, meeting the phase V standard with less RON loss. In the late case, the ON loss is 0.4 point less than RSDS-II process, indicating the better selectivity of RAST technology. The commercial data over the long run time demonstrate that the product quality remains stable, though the sulfur content of material varies in a large range (391～1 580 μg/g), which is to show that the RSAT technology can meet the requirement of gasoline quality upgrading.
