Hydrocracking

UOP’s Hydrocracking technology is an important conversion technology for producing high-value naphtha or distillate products from a wide range of refinery feedstocks. Examples of these feedstocks include heavy straight-run vacuum gas oil, heavy synthetic crude gas oil, thermally or catalytically cracked stocks, or solvent extracted vacuum bottoms. Our hydrocracking technologies have a long history of commercial application, with more than 150 licensed units and more than 90 units currently operating worldwide.

In 1990, UOP joined forces with Unocal to create the Unicracking technology. UOP’s Unicracking process operates at elevated pressure and temperature, and consumes hydrogen. The unconverted fractionator bottoms product can be fed to an FCC unit or lube oil hydrofinishing unit, or it can be recycled back to the process for full conversion to lighter high-value products.

UOP can offer you a complete range of hydrocracking services and solutions:

  • Unicracking technology licenses.
  • A wide selection of Unicracking catalysts.
  • Select equipment for improved reactor operation.
  • A full range of engineering design and technical services.
