Introduction of Alumina Silica Gel

Silica Alumina Glue, also known as Alumina Silica Gel, is a transparent or translucent granular gel with a variety of properties and uses. The following is detailed information about Silica Alumina Glue:

I. Properties

Composition and structure: Silica Alumina Glue is mainly composed of alumina and silicon dioxide, and general commodities contain about 10% to 15% alumina. Its morphology is spherical and irregular.

Chemical properties: Silica Alumina Glue is chemically stable, non-flammable, and insoluble in any solvent except strong alkali and hydrofluoric acid.

Physical properties: Silica Alumina Glue is hygroscopic, but worse than silica gel. It has high thermal stability and is suitable for temperature swing adsorption.

Other characteristics: Silica Alumina Glue has excellent adsorption performance, especially under high humidity conditions, its adsorption capacity is 6-10% higher than that of fine-porous silica gel.

II. Application

Petrochemical: Silica Alumina Glue is mainly used as a catalyst and catalyst carrier in the petrochemical industry, such as a catalyst carrier for petroleum catalytic cracking or other organic synthesis.

Industrial application: Silica Alumina Glue is used in industry for dryers, liquid adsorbents and gas separation. In addition, it can also be used to separate light hydrocarbons from natural gas, reduce the dew point of hydrocarbons, and produce natural gas gasoline.

Gas purification: Silica-alumina gel can be used as a common desiccant, catalyst and its carrier, and can also be used as a pressure swing adsorption separation agent, especially suitable for temperature swing adsorption separation agents at higher temperatures.
