Increasing the hydrogenation activity of commercial catalysts for selective hydrocracking
- and others
The catalysts generally used in hydrodewaxing or selective hydrocracking of n-paraffins are zeolites with the pentasil structure: TsVK, TsVM, TsVN, and Ultrasil. For use in the production of high-quality transformer oils from paraffinic feedstocks, these catalysts have not only a high cracking activity but also an adequate hydrogenating activity. Catalysts containing a nickel-molybdenum complex (or nickel molybdate synthesized by a specific method) are higher in hydrogenating activity in comparison with catalysts in which the metals are introduced by coextrusion or impregnation. Precipitation of a nickel-molybdenum complex on a solid support (aluminosilicate or zeolite) tends to increase its hydrogenating activity, so that the content of the hydrogenating metals in the catalyst can be reduced. This report describes studies on catalysts based on TsVM and TsVN high-silica zeolites.
