Catalyst Recovery Filters
A catalyst is any substance that induces a chemical reaction without participating in it directly, remaining unchanged post-process. The use of catalyst filtration systems, including precious metal catalyst filters, to effectively trap and reclaim catalysts like platinum and palladium can significantly enhance your system’s efficiency, reduce waste, and cut costs. Mott’s three precious metal catalyst filters are meticulously engineered to capture +99% of catalysts for recycling or reclamation, ensuring superior filtrate quality. The Mott HyPulse® LSI is perfect for various clean-in-place backwashes, from discharging an approximate 15 wt.% slurry to an approximate 50 wt.% wet cake. For capturing submicron particles, the HyPulse® LSX cross-flow filter ensures less than 50 ppm filtrate quality, preventing media blinding by small catalyst particles. Meanwhile, the HyPulse® LSM excels in applications with dense particles like Raney nickel, combining configurable filtration and backwash operations with gravity settling for high solids loading streams. All three technologies, designed for precise process conditions, can endure operating temperatures up to 1700°F, high operating pressures, and corrosive environments, making them invaluable for systems utilizing precious metal catalysts.

Product Specs
| Typical Catalysts |
Mott filters are often used to capture the following catalyst – Platinum, palladium, rhodium, nickel, and various specialty catalysts. |
|---|---|
| Filtration Efficiency |
Media grade elements down to 0.2 μm are available to capture even the smallest catalyst particles, resulting in 99%+ capture efficiency, typically leading to a 10-20% reduction in total catalyst costs for manufacturers. |
| Vessel Diameter |
Standard Diameters – 4” to 72” diameter vessels are standard to accommodate a wide range of flow rates. Custom vessels are available upon request, consult factory. |
| Material Choices |
Standard filter element alloys – 316L SS, 310 SS, Hastelloy® C-276, Hastelloy® X, Monel 400, Nickel 200, Inconel® 600. Standard vessel alloys – 316L SS, Hastelloy®, Carbon Steel, 316 SS. Other alloys are available, consult factory |
| Operating Temperatures |
Alloys with temperature resistance up to 1700° degrees Fahrenheit are available. Custom alloys available to accommodate unique operating temperatures, consult factory. |
| Cleaning |
Mott LSI filters for catalyst processes are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or through a backwash cycle. Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned. |
The Mott Filter Design Process
Filter Feasibility Testing – In our Customer Innovation Center, we will replicate, or very closely correlate, your process conditions to determine the appropriate media grade and material for your application, specifically focusing on precious metal catalyst filters and catalyst recovery filters. We will provide you with a comprehensive, in-depth analysis to prove the feasibility of using porous metal in your catalyst recovery process and furnish you with a comprehensive ROI justification.
Pilot Testing – As an option, we can install a pilot unit in your facility enabling you to witness, first-hand, how our precious metal catalyst filters will perform in your process stream and under your actual operating temperatures and pressure conditions.
