中文摘要： 随着环保要求的日益提高，世界各国对汽油的生产提出了更加严格的要求。我国商品汽油的80 %来自催化裂化（FCC)汽油，其硫含量远远超标，因此FCC汽油超深度脱硫是我国目前生产清洁油品的关键。传统汽油加氢脱硫技术具有能耗高、汽油辛烷值损失较大或收率较低等缺点。本项目拟合成出具有不同晶态结构的氧化铝材料，并将其作为催化剂载体，制备加氢脱硫催化剂；并在前期开发的微波连续加氢脱硫体系上，系统研究各晶型氧化铝与FCC汽油加氢脱硫性能之间的关联；研究微波场对各晶型氧化铝及其负载型加氢脱硫催化剂之间的协同作用，以及含硫化合物在微波场中的行为，揭示微波加氢脱硫作用机理。为定向开发高效微波响应加氢脱硫催化剂，及该技术的最终工业化应用奠定坚实的理论基础，对生产满足新标准的超低硫汽油具有重要意义。

英文摘要： With higher demands of environmental protection, the requirement of gasoline quality is increasingly stringent all around the world. In China, about 80% of the commercial gasoline is from FCC gasoline, which has significantly high sulfur content, ultra deep desulfurization of FCC gasoline therefore becomes the key issue. Traditional hydrodesulfurization (HDS) technologies have disadvantages of higher energy consumption, lower octane number and liquid yield. This project intends to synthesize a kind of alumina with different crystalline structures, and then prepare HDS catalyst using the synthesized alumina as support. Systematically investigate the relationship between alumina based catalyst and its HDS performance using the former developed continuous microwave HDS system. Study the microwave synergistic effect on the alumina with different crystalline structure and its supported HDS catalyst. Reveal microwave HDS mechanism based on the sulfur compounds behavior in microwave field and the interaction between microwave and catalyst. This technology will establish a solid theoretical basis for the ultimate industrial application and the development of high HDS performance catalyst under microwave irradiation. It is significant to the practical production of ultra low sulfur gasoline.
