(1) Introduction:
The inert alumina ceramic ball is broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc. There are lots of merits for it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.
This product, which had been developed by our group company, had gained the award of excellent new product and the prize of the science and technology improvement of Jiangxi province in 1988. In the same year, this product entered the national honor roll of the excellent new product. In 1990, it gained the national certificate of the science and technology achievements. In 1996, it also got the provincial certificate and the golden prize of the famous brand product. Of late years, it has always been recommended by SINOPEC. Since it entered the market, all circles of customers had realized that its properties and effects are the same as the foreign products, and some of the technological index has surpassed the same foreign products.
