Process Brief:
The material involves hydrogen fuel cell catalyst nanopowder. Ceramic membrane equipment and nanofiltration (NF) membrane equipment are used to remove auxiliary materials (acids, salts) from the product, achieving purification. Through a multi-stage filtration system comprising ceramic membrane clarification, ultrafiltration (UF), and nanofiltration (NF), the process performs graded purification to remove acids, salts, and other impurities from the extract, thereby increasing product concentration and purity.

Technical Advantages:

• Enables low-temperature filtration, effectively protecting the physicochemical properties of functional components;

• Ceramic membrane clarification produces a clear filtrate with complete removal of all solids;

• Nanofiltration offers excellent desalting efficiency, high concentration factor, and high product yield;

• The membrane filtration system enables batch and continuous production of functional components, reducing production intensity and lowering manufacturing costs.
