alumina ceramic ball-Catalyst bed support media
　　(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, reach to JM
and UOP standard.pass a high pressure shock test.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 ***8.
In the same year, this product entered the national honor roll of
the excellent new product. In ***0, it gained the national
certificate of the science and technology achievements. In ***6,
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.ÂÂ
