Chemicals and Catalysts

GTC supplies various proprietary chemical and catalyst products associated with our process technologies. 

Chemicals

  • TechtivSM-100 Extractive Distillation Solvent
This proprietary blended solvent is used in the GT-BTX® aromatics extractive distillation process. Its 
superior combination of selectivity and solvency make it a desirable alternative to other commonly used aromatics extraction solvents.
  • TechtivSM-200 Extractive Distillation Solvent
             This proprietary blended solvent is used in the GT-Styrene® extractive distillation process and is
             specifically designed for untreated pygas component extraction applications. 
  • TechtivSM-DS Extractive Distillation Solvent
             This proprietary blended solvent is used in the GT-BTX PluS® aromatics extractive distillation
             process and is specifically tailored for aromatics separation from cracked naphtha feedstock.

Catalysts

  • Selective Toluene Disproportionation Catalyst
             This shape-selective catalyst is used in the GT-STDPSM process and is capable of producing    
             paraxylene-enriched mixed xylenes product (>85 wt.% paraxylene), which can be efficiently    
             purified to high-purity (99.9 wt.%) in the CrystPXSM process. 
  • Transalkylation Catalyst
             This catalyst is used in the GT-TransAlkSM process and is capable of handling high concentrations
             of C9+ aromatics along with toluene to produce high-purity benzene and equilibrium mixed xylenes.
  • Xylene Isomerization Catalyst
             This EB-dealkylation type isomerization catalyst is used in the GT-IsomPXSM process and is 
             capable of achieving high EB conversion rates while returning the paraxylene-depleted feed to    
             equilibrium concentrations. 
  • Pygas Hydrotreating Catalysts
              These catalysts are used to remove di-olefins (1st stage hydrotreating) and olefins (2nd stage 
              hydrotreating) in pyrolysis gasoline.  The C6- C8 cut after 2nd stage hydrotreating is the feedstock
              for our GT-BTX® process to produce benzene, toluene, and mixed xylenes.
  • Aromatization Catalysts 
             These catalysts are used in Aromatization Technologies either for octane improvement of straight-             run gasoline and natural gas condensate or aromatics production with C4 - C8 olefins as feedstock.
