With the Yzeolite as a carrier, nickel nitrate as the active component, a sorbent for FCC gasoline adsorption desulfurization is prepared. Treated with moist gas under the different temperature, the prepared adsorbent has a specific surface area 780 m2/g and aperture about 0.742 nm. The prepared sorbent are used for FCC gasoline desulfurization in the microreactor, the effects of space velocity on adsorbent activity of adsorption desulfurization are investigated. The results show that the adsorbent has good activity and its adsorption desulfurization rate reaches 89% when the active component content in the weight of Yzeolite is 15% and treated at 950 ℃, and space velocity is 0.5 h-1.
