Catalyst Filters for Precious Metal Catalysts


Many chemical reactions are initiated and aided by catalysts of various types. These catalysts are often made of precious metals such as Palladium (Pd/C), Platinum (Pt/C), Rhodium (Rh/C), Ruthenium (Ru/C) etc. Typically 5% and 10% palladium/platinum/rhodium/ruthenium on activated carbon/alumina catalysts finds application in variety of reactions like hydrogenation, reduction, oxidation etc. Since precious metal catalysts are expensive, their recovery is very important from economic and environmental point of view. In traditional sparkler filters, leaf filters, bag filters or plate and frame filters which operate on a batch or a semi-continuous mode, filtrate needs to recirculate for complete filtration. This increases the time and cost of the process. Also these filters require filter aid for proper filtration and they have limitation of size of filtration area. Compared to these filters, sintered metal candle filters offer 100% recovery in one cycle with shortest possible filtration time. In addition to providing superior filtration in a single pass, these filters reduce operator exposure to process materials and volatile emissions.

Many types of backwashable filters are available in different mechanical configurations. What truly distinguishes one from the other is the filter candles/ cartridges or media used in the filter. It is the key parameter for achieving the desired separation and ensure long operating life. Nano-Mag make filters are fitted with GKN make state of the art Sintered metallic candles, which are designed for true ‘Surface Filtration’ technology. In Surface Filtration, particles are retained mostly on the surface of the candle, thus preventing choking of candles over a period of time. These candles are coated with metallic membrane which prevents the catalyst particles from getting penetrated in the sintered wall of the filter candle and enhances its life. Our Noble Metal Catalyst Filters are specially designed for filtration of various catalysts such as Palladium, Platinum, Rhodium, Ruthenium etc. We work in collaboration with our international business partner GKN Sinter Metals, Germany to offer you a best solution for your filtration requirements. GKN Sinter Metal Filters is one of the world's foremost manufacturers of porous metal elements with defined pore size. We provide Zero Hold-up filters to suit various filtration areas and design conditions. We also supply customized filters for critical applications.
