What is the mainstream process of catalyst filtration and recovery at present?

At present, in the traditional and common processes of catalyst recovery, metal filter media, namely metal tubular filter elements, are mostly used. The new process adopts inorganic membrane separation, the difference is that the existing ultrafine catalyst metal filter element can not be completely intercepted, which leads to catalyst consumption or affects the quality of downstream products. The application of ceramic membrane in catalyst recovery can solve this technical problem. However, ceramic membrane technology is more expensive, depending on the recovery value of your catalyst and the added value of the product. Nanjing filtration industry has done a lot of research and application in this field, and there should be a lot of experimental data accumulation. You can ask.
