Abstract
A multi-stage process is described for upgrading pyrolysis tar, such as steam cracker tar, by hydroprocessing in at least two stages. Hydroprocessing in a first stage is performed in the presence of a utility fluid. The utility fluid has a boiling point distribution from about 120° C. to about 480° C. and is separated from the first stage product.
