High Specific Surface Calcium Hydroxide Desulfurizer refers to calcium hydroxide with an exceptionally large specific surface area, typically exceeding 50 m²/g.
Core Features & Benefits:
1. Superior Adsorption Capacity Efficiency: Removes >95% of sulfur dioxide (SO₂) from flue gas, with broad adaptability to gas temperatures (0-430℃), minimal temperature drop, and excellent fluidity. It also has a relatively high removal rate for acidic gases such as hydrogen chloride and hydrogen fluoride.
2.Low construction investment and environmental protection: no water consumption, no hazardous waste generation, no wastewater discharge, no carbon emissions, and by-products can be recycled. It can replace some high-cost adsorbents (such as activated carbon), reducing environmental governance costs; as an alkaline material, it is naturally non-toxic, and the desulfurization product (CaSO₃) is harmless to the environment.
Wide Application: Demonstrates significant advantages in flue gas desulfurization across industries including environmental protection, new materials, steel, coking, industrial silicon production, sodium silicate manufacturing, photovoltaics, lithium battery production, cement, and waste-to-energy plants, positioning it as a high-efficiency functional material.

High-surface-area calcium hydroxide, with its unique pore structure, ensures that HCl and SO₂ emissions in flue gas are significantly below the stringent standard of 10mg/m³. Its highly efficient chemical reaction mechanisms—such as the reaction between Ca(OH)₂ and SO₂ to form CaSO₃ and H₂O, as well as the reaction with HCl to produce CaCl₂ and H₂O—can be completed in an extremely short time, with a utilization rate exceeding 85%. Moreover, its superior flowability effectively prevents pipeline clogging and other issues in practical applications, further enhancing operational convenience and safety.
