Filtering powdered catalyst
Thread Content
I have a question for everyone: We have a powdered catalyst that is added to two organic liquids to facilitate a catalytic reaction. The reaction is carried out in a reactor: the reaction temperature is 280 degrees, the pressure is 5.0 MPa, and after 3.0 hours of reaction, the liquid product is removed from the reactor. The question is how to filter out the powdered catalyst? It also needs to be filtered while hot. Is the filtration temperature 200 degrees? Since the catalyst is used once, it is not applicable. So I would like to ask everyone: How is this filtration step carried out in industry? What filtering equipment should be used? Please let those who know share their thoughts.
Forgot to mention: the catalyst particle size is 150 mesh.
You can try Hebei Meibang’s metal membrane filter.
Can this metal membrane filter be heated to 200 degrees for hot filtration?
150 mesh, high temperature of 200 degrees – this is not difficult to handle. A Lützelholz stainless steel filter element will do
Do we still need the metal membrane filter from Hebei Meibang for that filter? :)

The membrane is made of sintered stainless steel, offering good strength and heat resistance; it can be used for filtration while still hot, and it works fine in any environment that is not highly acidic or containing high levels of chlorine. Membrane filters and stainless steel sintered filter elements are essentially the same thing; those with small pores are called membrane filters, while those with larger pores are called filter elements. Currently, over half of the caprolactam manufacturers in China use this company’s filters; it is also a slurry system, with catalysts having a particle size of 200 to 500 mesh.

In the case of a strong acid and high-chlorine system, you can choose ceramic membranes that offer better chemical stability; they also have good heat resistance, though the downside is that the material is somewhat brittle.
A metal membrane filter will do! Multiple material options!
Could you recommend a model and price for a metal membrane filter? The processing capacity is 0.5 tons of oil per hour
