Effect of hydrodynamic conditions on the hydrocracking process

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    Model studies of the three-phase fluidized bed, under conditions where the physical properties of the cold system are approximately similar to properties of the real system under operating conditions, have shown the necessity for including recirculation of the hydraulic recycle in the scheme of hydrocracking in a three-phase fluidized bed.

  2. 2.

    In operating the three-phase fluidized-bed hydrocracking pilot installation with different kinds of charging stock, the cold model indices for phase velocities including velocities in holes of the distributing grid were substantiated, and isotropic condition of the temperature field in the pilot installation reactor was determined.

  3. 3.

    The technical feasibility of three-phase fluidized bed hydrocracking was demonstrated both in the case of distilling the heavy distillates and run-down distillation of residuals,and prospects for commercial hydrocracking of residuals from crudes with high sulfur content were revealed.
