ET-1 type dechlorination agent is an efficient dual function purification agent used under low room temperature conditions, widely used in the petrochemical and nitrogen fertilizer industries for gas-liquid phase dechlorination. When the HCl content in the export is less than 0.1× At 10-6 (v/v), the original particle size penetrates the chlorine capacity by more than 8%; ET-1 also has excellent desulfurization performance. When the sulfur content in the purified gas at the outlet is less than 0.1mg/Nm3, the H2S sulfur capacity reaches 20%, and the COS sulfur capacity and CS2 sulfur capacity reach 2.0%, respectively.
