SDG acid gas adsorbent

SDG adsorbent is a new type of acid waste gas adsorption material, which is divided into SDG-1 type and SDG-2 type, respectively for the treatment of different acid containing gases, see the adsorbent performance table below. The SDG adsorbent was twice rated as the best practical extension technology by the former State Environmental Protection Administration. SDG sorbent, commonly known as dry acid gas sorbent, SDG acid waste gas sorbent (dry acid gas sorbent) SDG sorbent, is a dry acid gas sorbent, mainly used for the treatment of acid gas, stable and mature technology.

Advantage：

1, SDG acid gas adsorbent can purify a variety of acid gas, nitrogen oxides；

2, SDG adsorbent purification efficiency is high；

3, SDG adsorbent maintenance is simple and convenient；

4, SDG adsorbent is safe to use, high temperature resistance of more than 300 degrees；

5, SDG adsorbent non-toxic non-regeneration, no secondary pollution。
