More Information
Summary:The invention relates to a utility fluid, such as a fluid containing aromatic and non-aromatic ringed molecules, useful as a diluent when hydroprocessing pyrolysis tar, such as steam cracker tar. The specified utility fluid comprises 10.0 wt % aromatic and non-aromatic ring compounds and each of the following: (a) 1.0 wt % of 1.0 ring class compounds; (b) 5.0 wt % of 1.5 ring class compounds; (c) 5.0 wt % of 2.0 ring class compounds; and (d) 0.1 wt % of 5.0 ring class compounds. The invention also relates to methods for producing such a utility fluid and to processes for hydroprocessing pyrolysis tar.
