In recent years, with the increasingly strict environmental requirements, gasoline standards have been continuously improved in China, the standard for automotive gasoline (GB/T 17630-2016) stipulates that the sulfur mass fraction in the National V grade gasoline standard should not exceed 10 μg/g. At present, fluid catalytic cracking gasoline accounts for about 70% in gasoline pools in China. Catalytic cracking gasoline has a relatively high sulfur content, mostly between 300 and 600 μg/g, and desulfurization treatment is very necessary [1]. The S Zorb adsorption desulfurization process technology [2], which uses adsorption to desulfurize catalytic cracking gasoline, has the characteristics of high desulfurization rate, low octane value loss, low hydrogen consumption, and low operating costs. It is currently one of the key technologies for improving the quality of catalytic cracking gasoline through desulfurization treatment in China. Currently, multiple S Zorb units have been put into operation in major refineries in China, but the operating level varies and needs to be optimized [3–5].
