Alumina catalyst carrier & support
This series of products with large surface area, pore volume stability, good mechanical strength, low wear, pore structure suitable, low impurity content, active component impregnation characteristics and so on. The company produces different types of aluminum hydroxide as a raw material, can produce a variety of forms and different performance indicators of the catalyst carrier. This product is mainly used for the preparation of oil refining, chemical catalysts, especially petroleum distillate hydrogenation catalyst, can also be used directly as industrial adsorbents, desiccant use. Carrier can be produced according to user requirements of the following carriers: cylindrical, spherical, Clover, hollow and Rasching ring carrier.
Microsphere Alumina Carrier
These products are white sphere with relative smaller diameters, and are made both by spray pelletization and rolling. Because of the even structure and high crush strengrth, our spherical carriers will not crack when face water and fluctuation of temperature. The high attrition index minimize the lost of active ingredients thus are widely applied in precious metal catalyst.

【Applications】
Can be used as catalyst carrier for many kinds of liquid or gas in steel smelting, petroleum chemistry, water purification, chemical fertilizer and other fields.
Alumina Raschig Rings is a common used shape for alumina catalyst carrier, and has been extensively used in petroleum industry, chemistry, natural gas industry as carrier and support material for catalyst in reactors. This carrier mainly used to increase the distribution area of gas or liquid, to support and protect catalyst active ingredients.
