Abstract: The reasons of octane number loss of Jinling II-S Zorb unit gasoline were analyzed in three aspects of the properties of the raw material, the sulfur and carbon contents on adsorbent, as well as the process operation. The measures of changing the method for blending Yangzhou gasoline, improving the sulfur and carbon contents on the adsorbent, reducing the hydrogen flow rate, lowering the reaction pressure and increasing the reaction temperature were optimized and the octane loss of the refined gasoline was significantly reduced.

Key words: S-Zorb, octane number loss, gasoline, adsorbent activity, operation optimization
