| Micro-pore ceramic ball |
| |
 Micro-pore ceramic ball (or filtration ceramic ball) has the same function of supporting & covering catalyst and diversify gas and liquid, as the function of inert alumina ceramic ball. Besides, it can adhere and filter the impurity in oil and catalyst supporting & carrier, which can protect catalyst and prolong the running period of the equipment.

| plum blossom supporting ball series |
| |
 Newly successfully developed plum blossom supporting ball series products are our brand-new products by using latest technology, mainly used as supporting covering packing in reaction equipments of Petroleum & chemical, hydrogenation, refining, ethane, isomerization of aromatics and etc.. They can be used in primary reformer or secondary reformer, in order to lower the pressure of inside tower. With the advantages of larger surface area, better flow volume of gas & liquid, lower burthen of inside tower, these products can attribute to obvious economic benefits. |
