| Abstract: | The application of a supported hydrogenation catalyst SCB - 1 in an auxiliary reactor of cyclohexane unit of adipic acid production line was intro- duced in Liaoyang Petrochemical Company,PetroChiha. The results showed that catalyst SCB -1 had higher crushing strength and activity, its performance was superior to that of similar foreign catalyst, so that it could completely replace catalyst LD 143 which was made in France. Under the condition of optimizedprocess parameters, SCB -1 exhibited stable activity in a longer period, and its service life lasted from 6 years （design value） to 9 years. LD 143（6 t） used in 2 sets of cyclohexane unit were replaced by catalyst SCB - 1, so that 600 thousands Yuan was saved, and owing to the extended service life of catalyst, production cost of 750 thousands Yuan was saved. |
