title: INCREASING YIELD OF DISTILLATE FRACTIONS DURING COKING OF PETROLEUM RESIDUES
abstract: The research results of the influence of preliminary mechanochemical activation of heavy oil feedstock (oil-fuel, tar) on the output of their coking products are presented. Raw materials were activated by creating a cavitation effect when a hydrocarbon stream passes through a diffuser under a pressure. The pressure gradient on the diffuser ranged from 10 to 50 MPa, and the number of cycles of passage through the diffuser - from 1 to 5. It is shown that hydrodynamic cavitation processing results
