GT-TransAlk^SM

GT-TransAlk^SM process technology produces benzene and xylenes via transalkylation of the methyl groups  from toluene and/or heavy aromatics streams. The technology features a proprietary zeolite catalyst and can accommodate varying ratios of feedstock while maintaining high activity and selectivity.  GT-TransAlk^SM is especially well-suited for processing heavy aromatics (C9-C10+) with a long run length in order to maximize the production of xylenes from the aromatic feedstock.  High purity benzene is produced by simple distillation.  

Advantages:

• Simple, low cost fixed-bed reactor design
• Selective toward xylene production with high toluene / C9 conversion rates
• Physically stable catalyst
• Flexible to handle up to 100% C9+ components in feed
• Flexible to handle benzene recycle to increase xylene yields
• Moderate operating parameters; catalyst can be used as replacement to other transalkylation units or in grass roots designs
• Decreased hydrogen consumption due to low cracking rates
• Efficient heat integration scheme, reduces energy consumption
• Benzene can be produced at 99.9% purity by simple distillation
