Chemicals & Catalysts

GTC's proprietary chemicals and catalysts are used within all of GTC-licensed technologies, and are available as part of a comprehensive technology transfer package for either grassroots projects or for revamp and replacement of existing process units.  We offer a portfolio of Techtiv® series high-performing solvents that allow us to extend the range of operation and upgrade additional petrochemical components from wide boiling fractions.  Our solvents have versatile applications which transform low-value materials into premium value petrochemicals.  
 
Our portfolio of catalysts include a selective toluene disproportionation catalyst (STDP), transalkylation catalyst, xylene isomerization catalyst, pygas hydrotreating catalyst and aromatization catalyst.  To learn more about our chemicals and catalysts please contact us.
 

Techtiv Series Solvents

  • Techtiv® 500 Extractive Distillation Solvent

Techtiv 500 is a proprietary blended solvent used in GTC's  GT-BTX Select® aromatics extractive distillation process.  Its superior combination of selectivity and solvency make it a desirable alternative to other commonly used aromatics extraction solvents.

  • Techtiv® 200 Extractive Distillation Solvent

Techtiv 200 is a proprietary blended solvent used in GTC's GT-Styrene® extractive distillation process and is specifically designed for untreated pygas component extraction applications. 

  • Techtiv® DS Extractive Distillation Solvent

Techtiv DS is a proprietary blended solvent used in GTC's GT-BTX PluSSM aromatics extractive distillation process and is specifically tailored for aromatics separation from cracked naphtha feedstock.
 

Catalysts

  • Selective Toluene Disproportionation Catalyst

The selective toluene disproportionation catalyst is used in GTC's 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

The transalkylation catalyst is used in GTC's 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

The EB-dealkylation type isomerization catalyst is used in GTC's GT-IsomPXSM process and is capable of achieving high EB conversion rates while returning the paraxylene-depleted feed to equilibrium concentrations. 

  • Pygas Hydrotreating Catalysts

The pygas hydrotreating catalysts are used to remove di-olefins (first stage hydrotreating) and olefins (second stage hydrotreating) in pyrolysis gasoline.  The C6- C8 cut after second stage hydrotreating is the feedstock for our GT-BTX® process to produce benzene, toluene, and mixed xylenes.

  • Aromatization Catalysts 

Aromatization 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.
