Cyclohexanol Dehydrogenation Catalyst CD-6-Other Catalysts-

Cyclohexanol Dehydrogenation Catalyst CD-6

CD-6 is a high-performance catalyst engineered for the dehydrogenation of cyclohexanol to cyclohexanone, particularly suitable for large and medium-scale caprolactam production processes. Based on a copper-silicon system, it offers a broad operating temperature window, strong low-temperature activity, excellent selectivity, and consistent stability under industrial conditions.
