A method of upgrading refining streams with high polynucleararomatic hydrocarbon (PNA) concentrations can include: hydrocracking a PNA feed in the presence of a catalyst and hydrogen at 380&#xb0; C. to 430&#xb0; C., 2500 psig or greater, and 0.1 hrto 5 hrliquid hourly space velocity (LSHV), wherein the weight ratio of PNA feed to hydrogen is 30:1 to 10:1, wherein the PNA feed comprises 25 wt % or less of hydrocarbons having a boiling point of 700&#xb0; F. (371&#xb0; C.) or less and having an aromatic content of 50 wt % or greater to form a product comprising 50 wt % or greater of the hydrocarbons having a boiling point of 700&#xb0; F. (371&#xb0; C.) or less and having an aromatic content of 20 wt % or less.

Upgrading polynucleararomatic hydrocarbon-rich feeds

A process id disclosed for upgrading tars, typically those resulting from hydrocarbon refining processes, to products suitable for other uses, such as blending with other hydrocarbons to provide low-sulfur fuel oils or Emission Control Area-acceptable fuels. A low-sulfur hydrocarbon product obtained from the process is also disclosed.
