Raschig Ring Alumina Catalyst Carrier CAS 21645-51-2 Dia 4mm
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.
1.High-purity Alpha and Gamma Alumina structure.
2.High Crush Strength
3. Good performance in resistance to heat and impact
4. Low Attrition
Could be used in drying tower, absorption tower, scrubbing tower,
regeneration tower in chemistry, metallurgy, oxygen generation,
etc.
