MH Porous Ceramic Ball
1. Product Description
MH Porous Ceramic Ball is also called filtering ball. Pores are increased by 20~30% inside the inert ceramic ball. Therefore it can be used not only for supporting and covering the catalyst, but also for filtering and eliminating the impurities of grain, gelatin, asphaltine, heavy metals and iron ions of less than 25μm. If the porous ball is set on the top of a reactor, the impurities failing to be eliminated in the former process could be adsorbed in the pores inside the balls, thus protect the catalyst and prolong the operating cycles of the devices.
Based on the kinds, content and size of impurities existing in the hydrogen-adding, hydrogen-making and restructuring device, the user can select the product by their sizes, pores and porosity, or if necessary, add molybdenum, nickel and cobalt or other active components to prevent the catalyst from coking or poisoning.
