PROCESS FOR HIGHLY SHAPE SELECTIVE DEWAXING WHICH RETARDS CATALYST AGING |
摘要 |
This application discloses a process for catalytically dewaxing a feedstock whereby the aging of the dewaxing catalyst is miminized. A variety of feedstocks which possess moderate levels of nitrogen and sulfur may be dewaxed in this invention. The feed is treated by a catalyst system comprising two catalysts acting in synergistic combination, a hydrotreating catalyst and a dewaxing catalyst. The hydrotreating catalyst is preferably loaded with noble metals and is capable of operating at higher than usual space velocities. The dewaxing catalyst is downstream of the hydrotreating catalyst. The dewaxing catalyst further comprises a constrained intermediate pore crystalline material which is loaded with a noble metal.
