The Rentech Process - The Rentech Catalyst

Rentech utilizes its patented and proprietary iron-based catalyst in its Fischer-Tropsch reactors. The Rentech catalyst was chosen to be used over cobalt catalyst for two very specific reasons.

• The qualities of iron catalyst make it the most flexible catalyst, able to convert synthesis gas made from the widest range of hydrocarbon feedstocks with excellent economic efficiency.
  
  
• Specific to Coal-to-Liquids, iron catalyst can tolerate low levels of sulfur contamination and ammonia compounds that may get into the synthesis gas and still maintain economic levels of conversion. Cobalt catalysts have little or no resistance to poisons that may be contained in the synthesis gas produced from coal and once contaminated must be replaced.
