How to filter small particles in coal-based hydrogen production

I’ve heard that the American company GE uses ceramic filter elements; I’m not sure what the material of these elements is or what their dimensions are. If anyone knows, please let me know. Thank you!

The two methods currently used in China are metal powder sintering and ceramic membrane filtration; the specific materials and choices to be made depend on the conditions of the raw gas available at your site
Commonly used for dust removal, sedimentation, and bag filtration
Have ceramic or metal powder sintered filters been used on the 2nd floor? How to choose a model?
What are the specific differences between ceramic membrane filtration and metal powder sintering?
Ceramic and powder filtration work on basically the same principle. Nowadays, ceramic filters use ceramic membranes, while powder filters use metal membranes; the only differences lie in the materials used and the cost. It seems that the filtering materials produced by our company can be used just fine – at least in theory, it definitely works
For selection: are you planning to build the filter yourself? It’s quite difficult to do this if you have no knowledge at all of this industry
You can get in touch with Hebei Meibang; they produce excellent filter elements for use in the chemical industry!
Sintered porous metal filtration media possess excellent heat resistance and mechanical properties. At room temperature, the strength of sintered porous metal media is 10 times that of ceramic media, and even at high temperatures of 700°C, their strength remains several times higher than that of ceramic media. The good thermal conductivity and toughness of sintered porous metal media endow them with excellent thermal shock resistance; they are suitable for continuous reverse pulse cleaning, can be fully welded together, have good recyclability, and a long service life. Therefore, the sintered porous metal filtration technology exhibits excellent adaptability and advantages in high-temperature gas filtration applications.
