    Detailed information

    Characteristics of product

    ZT-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 20-30% 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 <25 μm 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.

    As the sorts, content, and particle sizes of the impurities in the raw materials within the hydrogenation and adsorption or drying are different among the hydrogen producing, customers can choose the porous ceramic ball according to the different pores diameter and the number of pores. In addition, if it is needed, customers could load the active compositions as Mo, Ni, and Co etc., in order to protect the catalyst from carbon laydown, poisoning or agglutinating.

    Chemical and physical properties


    Types and specifications

    For ZT-PCB porous ceramic ball, there are 12 assortments on every 5% as a grade in accordance with the AL2O3 content from 25% to 80%. There are twelve diameter sizes:Ø3,Ø6,Ø8,Ø10,Ø13,Ø16,Ø20,Ø25,Ø30,Ø38,Ø50, andØ75. Further, we can also provide the product as customers required specification and shapes.

    Notice to ordering goods

    a)When ordering goods, customers should correctly choose the outward sizes and specifications of the porous ceramic ball according to the requirement of design.
    b) As to the operating temperature and the loading amounts of the related equipment, customers should consult with our technological personal, and relevantly think over the appropriate margins.
    c) If it is necessary to load the active constitutions as Mo, Ni, and Co etc., customers had better put forward it while ordering goods.
