Macro-pored Micro-spherical Silica Gel: High-Performance Catalyst Support for Petrochemical Industry

In the petrochemical and chemical industries, the efficiency of a catalytic process often depends on the quality of the catalyst support. A good support must provide a high surface area, uniform pore structure, excellent thermal stability, and sufficient mechanical strength to withstand demanding operating conditions.

Macro-pored micro-spherical silica gel is engineered to meet these exact requirements. With its uniform internal micro-porous structure and large pore diameter, it has become a preferred catalyst and catalyst support material for producing key industrial chemicals such as melamine, phthalic anhydride, maleic anhydride, cis-butadiene rubber, and acrylonitrile.

Whether you are refining petrochemical products, removing aromatic hydrocarbons, or performing selective adsorption and separation, macro-pored micro-spherical silica gel delivers reliable performance.

Macro-pored micro-spherical silica gel is a white, transparent or translucent spherical material. It is manufactured with a controlled pore structure that provides:

8.0–12.0 nm

300–550 m²/g

0.8–1.3 mL/g

0.92 kJ/(kg·°C)

0.167 kJ/(m·h·°C)

Its stable physical and chemical properties, good thermal stability, and high mechanical strength make it suitable for both catalytic and adsorption applications.

consistent pore size distribution for predictable performance.

300–550 m²/g, providing abundant active sites for catalysis.

0.8–1.3 mL/g, allowing efficient mass transfer.

suitable for high-temperature catalytic processes.

resists attrition and crushing in industrial reactors.

improves flow characteristics and reduces pressure drop.

multiple size ranges available to match your process.

Note: Rattler loss is not applicable to the 125–180, 75–150, and 50–100 μm size ranges. Specifications can be customized according to your process requirements.

Macro-pored micro-spherical silica gel is widely used as a catalyst or catalyst support in the production of:

Its large pore size and high surface area allow active catalytic components to be well dispersed, improving reaction efficiency and selectivity.

It is used in the refining of petrochemical products to remove aromatic hydrocarbons. The uniform pore structure enables selective adsorption of unwanted compounds while preserving valuable product streams.

The material is suitable for the selective adsorption and separation of organic gases and liquids. It can be used in fixed-bed or moving-bed systems for purification and separation processes.

Macro-pored micro-spherical silica gel can remove multivalent harmful elements from water through ion exchange. This makes it useful for environmental protection and water treatment applications.
