SDT-DS105 Room temperature desulfurizer for shift gas
1. Uses and characteristics
SDT-DS105 is a strip desulfurizer with iron salt as the basic raw material, 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, large sulfur volume, high porosity, high purification degree and good water resistance, and is used for the dry removal of hydrogen sulfide and small molecule mercaptan and carbonyl sulfur in the process of synthetic ammonia production.
Principle of desulfurization:
FeO(OH)＋2H2S 
FeSSH +2H2O

4. Packaging, storage and transportation
1. The desulfurizer is packed in 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.
