GT-STDP^SM

GT-STDP^SM produces paraxylene-rich mixed xylene along with high purity benzene streams from toluene.  This toluene disproportionation technology boasts high toluene conversion rates and integrated production routes.  GT-STDP^SM features a commercially-proven proprietary catalyst with high activity and selectivity to paraxylene.

Advantages:

• Simple, low cost fixed-bed reactor design
• Drop-in catalyst replacement for existing hydroprocessing reactors
• Paraxylene enriched to over 90 percent in the xylene stream
• On-specification benzene with traditional distillation
• Physically stable catalyst
• Low hydrogen consumption
• Moderate operating parameters; catalyst can be used as replacement to traditional toluene disproportionation units, or in grass roots designs
• Efficient heat integration scheme, reduced energy consumption
• Turnkey package for high purity benzene and paraxylene production available from licensor
