In order to study the desulfurization of FCC gasoline, Zn/NaY zeolite FCC gasoline adsorbent was synthesized by impregnation method. The effects of space velocity, adsorbent bed temperature, adsorbent roasting temperature and roasting time on the desulfurization rate of FCC gasoline were investigated by adsorbent and fixed bed process. The results showed that the desulfurization rate of FCC gasoline reached about 85% under the conditions of 0.5 h-1 air velocity, 35°C adsorbent bed temperature, 700°C adsorbent roasting temperature and 4 h roasting time. Adsorption desulfurization as a technology with many advantages, such as low investment, low operation cost, complete desulfurization, had good application prospects and popularization value. To develop a fixed bed adsorption desulfurization technology for FCC gasoline which meets the requirements of V gasoline quality standards of producing countries.
