摘要:综述了国内外葸醌法流化床与固定床催化剂的研究进展,并且重点介绍了它们的优点和缺点,总结出各
种因素对镍催化剂和钯催化剂催化氩化性能的影响,同时单独介绍了葸醌加氩催化剂在选择性、活性等方面的
内容。还介绍了氯化反应器的特点和研究进展,并进行了比较。在详细比较了流化床与固定床生产技术优缺点
的基础上,总结出流化床相比于固定床技术具有生产成本低、醌降解少、催化剂利用率高、氢效高等优点
与此同时,简单介绍了蔥醌法流化床和固定床反应器应用方面相互比较的数据,得出流化底在大规模装置生产
方面具有明显优势。最后指出煎醌法流化床技术将取代国定床技术成为国内煎醌法的发展方向;同时展望了未
来醌法的发展趋势,并提出日前研究的难点、重点及发展建议

Researches on the catalysts with high catalylic activity and selectivily for the hydrogenation reaction
are reviewed, The characteristics and research progress of hydrogenation reactors are also introduced
and compared. Based on the detailed comparisons between the fluidized bed and fixed bed, it is
concluded that the production with fluidized bed has many advantages of relative lower cost, less
anthraquinone dcgradation, high catalyst utilization ratc and high hydrogenation cfficicncy. From an
application perspective, the diferences between lidi/ed bed and fixed bed are introduced. The paper
Minally points out that the production with fluidized bed has become the developing tendency of the
anthraquinone route and will replace the process with [ixed bed. The practical research difficulties
