Zinc oxide desulfurizer is widely used in the fine desulfurization of various petrochemical raw materials gas and industrial gas, with the advantages of high desulfurization precision and large sulfur capacity. Zinc oxide desulfurization agent is divided into normal temperature zinc oxide desulfurization agent and medium temperature (high temperature) zinc oxide desulfurization agent, the former's use temperature 10 ~ 120 ℃, the latter is 220 ~ 450 ℃, clover appearance, 30% increase in external surface area.
