Chemicals and Catalysts

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

Chemicals

This proprietary blended solvent is used in the GT-BTX® aromatics extractive

distillation process and is characterized by its superior combination of selectivity and

solvency when compared to other commonly used aromatics extraction solvents.

This proprietary blended solvent is used in the GT-Styrene® extractive

distillation process and is specifically tailored for untreated pygas component

extraction applications.

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.

This shape-selective catalyst is used in the GT-STDP^SM 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 CrystPX^SM process.

This catalyst is used in the GT-TransAlk^SM process and is capable of handling high

concentrations of C9+ aromatics along with toluene to produce high-purity benzene

and equilibrium mixed xylenes.

This EB-dealkylation type isomerization catalyst is used in the GT-IsomPX^SM process

and is capable of achieving high EB conversion rates while returning the paraxylene-

depleted feed to equilibrium concentrations.

These catalysts are used to remove di-olefins (1^ststage hydrotreating) and olefins (2^nd stage

hydrotreating) in pyrolysis gasoline. The C₆- C₈ cut after 2^nd stage hydrotreating is the feedstock

for our GT-BTX® process to produce benzene, toluene, and mixed xylenes.

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.
