porous ceramic ball

Description

WH-PCB porous ceramic ball that is also called the filtrating ceramic ball is prepared by opening holes on the basis of the former inert alumina. Thus, there is the same bulk void volume as the inert ceramic ball. Therefore, it can play the roles of covering or supporting the catalyst, and separating the gas and liquid. At the same time, there is ****0% pore volume of structure increased, which has the adsorbing capacity, so that it may be utilized to the impurities filtrating in the oil. As there are such different patterns in the oil as the granular, gum forming, asphaltene, and heavy metals, though these impurities have been filtrated some through the raw material filtrating equipment, there are rather some of the impurities remained (such as <*5 Î&frac*4;m granular impurities and ferrous ions). If the porous ceramic ball is loaded on the top of the reactors, the impurities, which is still remained through the raw material filtrating equipment, can be adsorbed in its pores, therefore, the catalyst is protected and the under-stream period is guaranteed.
