대표청구항 ▼

1. A heavy hydrocarbon treatment method, comprising: (a) providing a heavy hydrocarbon having a mass density (measured at 15° C.) ≧1.0 g/cm3 and a kinematic viscosity (measured at 50° C.) KVi≧30 cSt;(b) cavitating the heavy hydrocarbon to produce a cavitated heavy hydrocarbon having a kinematic viscosity (measured at 50° C.) of KVc, wherein (i) KVc is =(y*KVi) and (ii) y is ≦0.95 and wherein cavitation is conducted at a temperature between 50° C. and 200° C.; and(c) hydroprocessing at least a portion of the cavitated heavy hydrocarbon to produce a treated product. 2. The method of claim 1, further comprising: (d) providing a utility fluid which (i) comprises 1-ring and/or 2-ring aromatics in an amount ≧25.0 wt. % and (ii) has a final boiling point ≦430° C.; and(e) combining the utility fluid with the heavy hydrocarbon and/or cavitated heavy hydrocarbon before the hydroprocessing. 3. The method of claim 1, further comprising cavitating at least a portion of the hydroprocessed product. 4. The method of claim 1, wherein the heavy hydrocarbon comprises ≧90.0 wt. % of steam cracker tar, the steam cracker tar having one or more of (i) an IN≧85, (ii) a mass density (measured at 15° C.) ≧1.07 g/cm3, and (iii) a viscosity in the range of from 1000 cSt to 500,000 cSt. 5. The method of claim 1, wherein y is ≦0.7. 6. The method of claim 1, wherein y is ≦0.5. 7. The method of claim 1, wherein the hydroprocessing is catalytic hydroprocessing and the hydroprocessing conditions include a temperature in the range of 300° C. to 500° C., a molecular hydrogen consumption rate ≦267 standard m3 of molecular hydrogen per m3 of the heavy hydrocarbon, and a molecular hydrogen partial pressure in the range of from 34 bar (abs) to 48 bar (abs). 8. The method of claim 1, further comprising: producing a raffinate by separating from the hydroprocessed product one or more of (i) at least a portion of any vapor present in the hydroprocessed product and recycling at least a portion of the separated vapor to the hydroprocessing and (ii) separating from the hydroprocessed product at least a portion of those components having an atmospheric boiling point ≦430° C., wherein the utility fluid comprises at least a portion of the separated components of the hydroprocessed product. 9. The method of claim 8 wherein the raffinate comprises ≧90 wt. % of the hydroprocessed product's molecules having an atmospheric boiling point ≧290° C., and wherein the raffinate has one or more of (i) a kinematic viscosity (measured at 50° C.) <30 cSt, (ii) an IN≦80, (iii) a sulfur content ≦1.0 wt. %, and (iv) a mass density (measured at 15° C.) ≦1.1 g/cm3.
