The TFC series ferric oxide desulfurizer is a new type of desulfurizer developed based on comprehensive research of ferric oxide desulfurizers and activated carbon desulfurizers. It addresses the shortcomings of both ferric oxide and activated carbon, combining their strengths while overcoming the drawbacks of ferric oxide's tendency to pulverize and activated carbon's over-reliance on oxygen. Its overall performance is significantly superior to other dry desulfurizers available on the market. It can be widely used in industries such as biogas, coal chemical industry, petrochemical industry, natural gas industry, metallurgy, and environmental protection, effectively removing hydrogen sulfide from water gas. It is also suitable for various chemical raw gas such as natural gas, liquefied petroleum gas, coke oven gas, flue gas, and industrial waste gas.

TFC-2 ambient temperature iron oxide desulfurization agent is a newly developed composite desulfurizing agent specifically formulated for the biogas industry, characterized by its unique application environment, high humidity in raw gas, and anaerobic conditions. It is particularly suitable for removing hydrogen sulfide from large and medium-sized biogas as well as household biogas. It also offers certain desulfurization effects on nitrogen oxides, sulfur oxides, and various organic sulfur compounds.
