Silica-alumina gel H type is a light yellow solid particle with stable chemical properties, high specific surface area and drying ability. Its surface polarity, thermal stability, adsorption and separation performance are better than fine-porous silica gel.
Silica-alumina gel H type is a light yellow solid particle with stable chemical properties, high specific surface area and drying ability. Its surface polarity, thermal stability, adsorption and separation performance are better than fine-porous silica gel. Due to its higher strength and lower wear rate, it has a longer life and higher cost performance.

Application
Silicate-alumina gel is very suitable for temperature swing adsorption and separation agent because of its stable characteristics under humidity changes and pressure changes. It is widely used in compressed air drying, natural gas drying, dry gas, and liquefied gas drying.
We can recommend the best adsorption solution according to customer needs, which can not only meet performance requirements but also reduce the cost of use.
