PRECIOUS METAL CATALYST RECOVERY IN HYDROGENATION IN AROMATIC CHEMICAL PROCESSING

فاقد چكيده

One common unit operation is filtration in the Hydrogenation reactions in Aromatic chemistry, petrochemical and fine chemical industry which uses a lot of specialty precious catalysts. Catalyst recovery after every operation is important and helps in reducing bottle-necks, downtimes and losses of precious metal catalyst in chemical processing. The Catalyst to be recovered from processes can be from a few gms to many kgs per batch. The high rising prices of these catalysts as well as environmental and work place regulations have forced companies to have good and efficient catalyst recovery systems.
