SDT-DS103 Special room temperature desulfurizer for biogas
1. Uses and characteristics
SDT-DS103 is a strip desulfurizer developed for biogas with iron salt as the basic raw material for biogas containing a large amount of carbon dioxide and water vapor, low pressure and unstable air flow, which is converted into special activated iron oxide by chemical synthesis and processed by adding composite additives and binders. The product has the characteristics of high active substance content, carbon dioxide resistance, large sulfur capacity, low resistance, high purification degree and good water resistance, and is used for the removal of hydrogen sulfide and small molecule mercaptan in biogas produced by various methods.
Principle of desulfurization:
FeO(OH)＋2H2S 
FeSSH +2H2O

3. Packaging, storage and transportation
1. The desulfurizer is packed in tons of bags or woven bags, lined with plastic bags.
2. Rolling, collision and violent vibration should be avoided during transportation to avoid crushing.
3. Under the condition of not damaging the packaging, it can be used normally after 1~2 years of storage.
