A chemical adsorbent specifically targeted at hydrogen chloride gas impurities.

A chemical adsorbent for the removal of hydrogen chloride impurities from gaseous or liquid hydrocarbons by the removal of hydrogen chloride impurities gamma-alumina and alkali metal carbonate or alkaline earth metal carbonate additives from gaseous or liquid hydrocarbons. The preparation method can be mixed extrusion method, impregnation method, rolling ball method or tablet forming method. The adsorbent has a strong hydrogen chloride removal capacity and can reduce the impurity content of hydrogen chloride in gas or liquid hydrocarbons to less than 0.5ppm. At this time, the adsorption amount of hydrogen chloride on the adsorbent can reach 25% (by weight).

Hydrogen chloride's Useful

1. Industrial production: Hydrogen chloride is widely used in industrial production, such as hydrochloric acid, chlorine, chloride and other chemical products preparation.

2. Chemical experiments: Hydrochloric acid (HCl) is a reagent commonly used in many chemical experiments to regulate the pH and acid hydrolysis of substances in the reaction.

3. Pickling and cleaning: Due to the strong acidity of hydrogen chloride, it can be used for pickling metal surfaces, cleaning dirt and oil stains.

4. Chlorination agent: hydrogen chloride can be used as chlorination agent in some chemical reactions, such as desulfurization reaction in petroleum refining process.
