High-Conversion Hydrocracking

HyK™

HyK™ is Axens high conversion Hydrocracking technology that converts middle distillates or heavy distillates into more valuable products. Apart from the conventional Straight Run VGO, other feeds that could be processed in a hydrocracker includes:

• Heavy Coker Gasoil (HCGO) produced from Delayed coker or Flexicoking process,
• Deasphalted oil (DAO) from SDA,
• VGO cut produced from Resid hydrocracker (ebullated bed or slurry technology),
• Straight run kerosene and diesel,
• LCO coming from FCC,
• LCGO from coker.

In order to adjust the product yields and meet the most profitable production targets it is necessary to choose the right process scheme for each project:

• “Once-Through scheme” offers the possibility to produce middle distillates and valorize the VGO feeds as top-quality Group III lubes or petchem feedstock,
• “Single Stage with Recycle scheme” boosts the conversion and selectivity towards valuable fuels with moderate increase of the investment cost,
• “Two-Stage scheme” offers the best selectivity towards high-value middle distillates or naphtha for petchem while minimizing the unconverted bleed.

HyK™ with Renewable Lipids Co-Processing

Renewable low carbon transportation fuels are playing an important role in the effort to reduce greenhouse gas (GHG) emissions. 

Backed by a long history of strong R&D programs with lipidic feeds and hydroprocessing technologies, Axens offer a complete range of solutions with a possible phased investment approach on the path to decarbonization.
