1. Product Description

    This product has been independently developed and manufactured by our company, and is primarily used for the removal of hydrogen sulphide from gases such as biogas, natural gas, semi-water gas, coke oven gas and petroleum refining gas. The chelated iron desulphurisation catalyst is a type of catalyst containing active iron ions, with a solution that is weakly alkaline. It features a high sulphur capacity, strong resistance to fluctuations in hydrogen sulphide levels, and high hydrogen sulphide removal efficiency, with a single-pass removal rate of up to 99%.

2. Technical Specifications
