摘要：
An effective deep oxidative desulfurization process, catalyzed by Na2WO4 and ionic liquid, was developed for real diesel prehydrotreated. A lower amount of ionic liquid was used, while good catalytic oxidation activity could be obtained under mild conditions. The sulfur content in the real diesel can decrease from the initial 200 to 23.2 ppm after the oxidative desulfurization process, and the sulfur removal rate can reach 88.4%. The catalytic system can be recycled directly after vacuum drying, and there is no obvious change on catalytic activity after recycling five times.
