Zinc Oxide Desulfurization Catalyst
ZnO Desulfurization Catalysts are widely used in feedstock purification processes for the production of hydrogen, ammonia, alcohols, and organic chemicals.
The main reaction of the desulfurization process is as follows:
H2S+ZnO=ZnS+H2
ZnO Desulfurization Catalyst is highly adaptable.
It can work in severe conditions with high sulphur absorption capacity, high activity, high strength, good sustainability for activity and sulphur absorption capacity, and good tolerance to high steam-to-gas ratio.
It can obtain satisfactory operation results both at higher ( about 400℃) and lower (about 200℃) temperatures.
