	Sulphur Removal. ActiSorb® S 7 is recommended for the removal of H2S, mercaptans, disulphides and thiophens in hydrocarbon feedstreams, ranging from naphtha to middle distillates.

Hydrodesulphurisation. Standard Catalysts for the hydrogenation of organic sulphur compounds in hydrocarbon feedstocks are the cobalt-molybdenum-type catalysts from the HDMax 200 series. These catalysts are used in both liquid and gas phase for all types of hydrocarbons, such as naphtha, LPG, natural gas and off-gases. For the hydrogenation of organic nitrogen compounds and/or olefin saturation the cobalt-molybdenum-based HDMax 310 catalyst is recommended.

H2S Removal. The ActiSorb® S series of ZnO based adsorbents is used for the removal of sulphur components such as hydrogen sulphide, mercaptans and COS from hydrocarbon feedstreams. ActiSorb® S 2 is the perfect solution when operating at high space velocities and elevated temperatures, while ActSorb® S 3 is recommended in applications with lower space velocities and higher inlet sulphur concentrations. The maximum bulk density catalyst ActiSorb® S 1 is ideal in applications where maximum sulphur pick-up per loaded unit volume is required. ActiSorb® S 6, a copper-promoted zinc oxide removes the remaining H2S to a value < 10 ppb under a wide range of operating conditions. Purification for natural gas containing low concentrations of total sulphur can also be performed by ActiSorb® G 1.

	Chlorine Removal. Süd-Chemie offers a range of adsorbents for the removal of HCl, ammonium chlorides and organic chlorine compounds, depending on the hydrocarbon feedstock and operating conditions. ActiSorb® Cl 2 and ActiSorb® Cl 6 are used for liquid phase applications, while ActiSorb® Cl2 and ActiSorb Cl 3 adsorbents are recommended in the gas phase.

	Fluorine Removal. ActiSorb® F adsorbs organic fluorine compounds and HF in hydrocarbon feedstocks.
