DX Process

GTC’s DX process converts ethylbenzene (EB) in C8 aromatics feedstock to high-purity benzene and ethane, and upgrades the mixed xylenes to premium grade.

Process Advantages

  • Simple, low cost fixed –bed reactor design
  • Flexible feedstock and operation
  • High EB conversion per pass can be nearly 100%
  • DX products are isomerized to equilibrium composition of xylene, which relaxes isomerization unit
  • Low ring loss at very high EB conversion
  • On-specification benzene with traditional distillation
  • Extremely stable catalyst
  • Low hydrogen consumption
  • Moderate operating parameters
  • Efficient heat integration scheme reduces energy consumption
  • Turnkey package for high purity benzene, toluene and paraxylene production available from licensor
