Sulfur and chloride impurities in industrial feedstocks can create significant challenges for downstream processing. Sulfur compounds may deactivate sensitive catalysts, while chloride contaminants can contribute to equipment corrosion and operational problems.
Selecting the appropriate purification catalyst or adsorbent helps chemical plants manage feedstock quality before steam reforming, CO shift conversion, methanation, ammonia synthesis and methanol production.
Our purification product range supports three important treatment requirements:
Organic Sulfur Conversion: Convert suitable organic sulfur compounds into hydrogen sulfide through catalytic hydrogenation.
Sulfur Removal & Polishing: Remove hydrogen sulfide and other sulfur compounds using metal-oxide-based desulfurization materials.
Chloride Removal: Capture hydrogen chloride from industrial gas and selected liquid hydrocarbon streams.
Different products perform different functions. The appropriate selection depends on the impurity composition, purification target and process conditions.
Our nickel-based methanation catalysts cover two main applications: residual CO and CO₂ removal from hydrogen-rich process gas, and methane synthesis for synthetic natural gas (SNG) production. The range supports new methanation units, catalyst replacement and existing plant upgrades, with catalyst selection based on feed gas composition, operating conditions and process requirements.

The operating values above are published references. Final catalyst selection and operating limits should be confirmed against the latest product specifications, feed gas analysis and reactor requirements. For SNG applications, heat management and catalyst configuration also require process-specific evaluation.
Different purification products operate under different temperatures, pressures and impurity loading conditions. The following table summarizes selected published product information to support preliminary catalyst comparison.
| Product Type | Reference Temperature | Reference Pressure |

Natural gas and hydrocarbon feedstocks may contain sulfur and chloride impurities that require removal before downstream catalytic processing.
Our purification product range provides options for organic sulfur conversion, hydrogen sulfide removal and HCl capture according to the required treatment stages.
Sulfur impurities in hydrocarbon feedstocks can negatively affect the catalysts used in steam reforming and other hydrogen production processes.
Suitable desulfurization materials can support feedstock pretreatment before sensitive catalytic stages.
Ammonia and methanol plants require suitable feed gas quality to maintain catalyst performance through reforming, shift conversion and synthesis stages.
Our purification products can support impurity removal before the relevant process units, depending on plant configuration.
Coke oven gas and coal-derived gas streams may contain different inorganic and organic sulfur compounds.
Selecting purification materials based on gas composition and process temperature is important for downstream treatment and synthesis operations.
Refinery gas and selected hydrocarbon feedstocks may require pretreatment to reduce sulfur or chloride contamination.
Our product range includes materials for different purification stages used in refinery-related and chemical manufacturing processes.
The most suitable catalyst or adsorbent depends on the specific impurities present in the feedstock and the required purification result.
1. Identify the Impurities
Determine whether the main contaminants are H₂S, COS, CS₂, mercaptans, other organic sulfur compounds or HCl. Different contaminants may require different treatment mechanisms.
2. Evaluate Your Operating Conditions
Confirm the process temperature, operating pressure, feed gas flow rate, space velocity and available hydrogen concentration where hydrogenation is involved.
3. Define Your Outlet Purity Requirements
Specify the acceptable outlet sulfur or chloride concentration according to the sensitivity of downstream equipment and catalysts.
4. Review the Purification Sequence
Organic sulfur hydrogenation, bulk sulfur removal, fine sulfur polishing and chloride removal may be carried out in separate stages. Material selection should consider the complete purification system.
5. Confirm Reactor & Catalyst Requirements
For replacement projects, provide existing catalyst specifications, reactor dimensions, bed volume, loading quantity and operating history.
With these details, our technical team can review suitable catalyst options for your application.
For EPC contractors, engineering companies and chemical plant project owners, selecting purification catalysts involves matching the material to the process design and target feed gas quality.
We can discuss available product specifications, required catalyst quantities and technical information for procurement evaluation.
For operating plants, replacing spent purification materials requires consideration of existing reactor conditions, contaminant loading and required outlet purity.
Share your current product details and operating requirements to explore available replacement options.
Where suitable, catalyst dimensions or physical forms may be discussed based on specific reactor and loading requirements.
Technical suitability and available customization options should be confirmed before procurement.
A hydrodesulfurization catalyst converts suitable organic sulfur compounds into hydrogen sulfide in the presence of hydrogen. A ZnO desulfurizer primarily removes hydrogen sulfide through reaction with zinc oxide. Both may be used at different stages of a feed gas purification process.
The selection depends on the type and concentration of sulfur compounds, operating conditions and required outlet concentration. Cu-Zn fine desulfurization materials may be suitable for selected low-sulfur polishing applications, while other products are used for different sulfur conversion and removal duties.
Not necessarily. Sulfur conversion, sulfur removal and chloride capture involve different material functions. A process may require separate products or treatment stages depending on the impurities present.
Please provide the feedstock type, gas composition, impurity concentrations, operating temperature and pressure, gas flow rate, target outlet quality and required catalyst quantity. Existing catalyst information is also useful for replacement projects.
