Macroporous chromatographic silica gel powder is processed from special silica gel as raw material, appearing as white uniform particles, fine, odorless and tasteless, with silicon dioxide as the main component. It features high purity, safety, and hygiene.

This silica gel utilizes differences in adsorption retention times for various substance components, enabling the separation and purification of mixed components of different substances. It is primarily used for refining petroleum products to remove aromatic hydrocarbons or as an adsorbent for acetylene in liquid air and liquid oxygen in the air separation industry. It can also adsorb acids and water in oil, as well as decolorize organic solvents. It is harmless to oil and internal combustion engines. It serves as a catalyst carrier, enzyme preparation carrier, and inorganic adsorbent. It is used as a desiccant for industrial gases and as a buffer desiccant for ordinary silica gel protective beds. In air conditioning systems, it supplements the shortcomings of conventional air conditioners. When used together, separate treatment of temperature and humidity becomes more effective, and refrigeration air regulation control can reduce pressure and excessive cooling capacity.
