Silica-Alumina Gel (WS)
This product is a fine-pored, water-resistant silica-alumina gel. It is generally used as a protective layer for fine-pored silica gel and fine-pored silica-alumina gel, and can also be used alone in situations where the content of free water (liquid water) is very high. When the operating system contains liquid water, the use of this product can also achieve a relatively low dew point.
Product Overview
【Properties】
This product is a fine-pore water-resistant silica-alumina gel. It is generally used as a protective layer for fine-pore silica gel and fine-pore silica-alumina gel, and can also be used alone under conditions with high content of free water (liquid water). When liquid water is present in the operating system, this product can also achieve relatively low dew points.
【Applications】
Mainly used for air drying in air separation processes, acetylene adsorption in the preparation of liquid oxygen and liquid nitrogen, drying of compressed air and various industrial gases. It serves as a liquid adsorbent and catalyst carrier in industries such as petrochemicals, electric power, and brewing, and is used as a protective layer for ordinary silica gel and silica-alumina gel.
When used as a protective layer, the dosage of this product is approximately 20% of the total usage.
