Learn Silica Alumina Gel Type H
Silica alumina gel H type is a slightly yellow substance with the chemical formula mSiO2.nAl2O3.xH2O. Compared to fine-pored silica gel, it has a similar adsorption capacity at low humidity levels (such as RH=10%, RH=20%), but its adsorption capacity at high humidity levels (such as RH=80%, RH=90%) is 6-10% higher than that of fine-pored silica gel. Its thermal stability (at 200°C) is over 150°C higher than that of fine-pored silica gel, making it highly suitable as a TSA (temperature swing adsorption) adsorbent.

Applications
-
Natural Gas Processing: Effectively separates light hydrocarbons from natural gas and reduces dew points, producing dry and pipeline-ready gas.
-
High-Humidity Drying: Desiccant of choice for environments exceeding 80% RH, protecting equipment and ensuring optimal processing conditions.
-
PSA and TSA Process: Ideal for TSA and PSA applications due to its exceptional thermal stability and high adsorption capacity across temperature ranges.
-
Catalyst and Carrier: Can be used as a catalyst itself or carrier for various catalytic reactions, contributing to efficient chemical processes.
-
Protective Layer: In presence of liquid water, approximately 20% (weight ratio) of Water-Resistant Si-Al-Silica Gel acts as a protective layer for Type H, enhancing its lifespan.
