Iron products for effective
desulfurization of biogenic gases

In addition to our extensive range of activated carbon products, we also offer iron hydroxide products. These are used to reduce the hydrogen sulfide (H2S) content in biogenic gases directly within the fermenter. Iron hydroxide is introduced along with fermentation substrates, during, the fermentation process. Our high quality products consist of purely natural, partially processed, iron with high purity.

SORB NEO: For coarse desulfurization within the fermenter

Iron hydroxide is introduced along with fermentation substrates to reduce hydrogen sulfide (H2S) during fermentation. SORB NEO is a pure natural iron hydroxide. Due to its high iron content, the extra amount of material added into the fermenter is low, and because of the purity of SORB NEO, there are no additional sediments.

Product properties:

  • Easy and safe to use
  • Non-hazardous material
  • Very high iron content
  • Natural product with a very low heavy metal content
  • No sedimentation from extra material input in the fermenter
  • Free-flowing and low-dust
  • Dry and easy storable

FEPS: for specialized desulfurization

FEPS has been specially developed for the removal of hydrogen sulfide from technical and biogenic gases. It is based on highly amorphous iron oxide, which efficiently and safely removes trace gases from the gas. A highly porous structure leads to a very high loading capacity, which also means FEPS is very cost-effective. The uniformly shaped and pressure-resistant pellets lead to a low and consistent pressure drop in the packed bed.

Product properties:

  • Very effective, high concentration of amorphous iron 
  • Safe handling, non-combustible
  • Stable, low incidence of dust, easy storable
  • Possible to load with a high amount of hydrogen sulfide

Good to know

What type of activated carbon do I need for my plant?

Based on a simple gas analysis, we establish the right solution for the efficient operation of your gas plant. Benefit from our experience and obtain a free consultation today!

Why does SILOXA prefer to discuss activated carbon in liters and not in kg?

Our market-leading activated carbon filters, have a maximum filling capacity in liters. To ensure your filter is always at optimal performance, our  high-quality activated carbon is measured and delivered in liters, not kilograms. The same applies for filters supplied by other manufacturers.

Why is high-quality activated carbon so light?

The lower the specific weight of activated carbon (in g/l or kg/m³), the higher the pore volume of the activated carbon. A high pore volume means a lager contact surface, which leads to better purification. High pore volume is a quality characteristic of high-quality activated carbon.
