UPGRADING CHALLENGED FEEDS AND PITCHES PRODUCED THEREFROM

Document Type and Number:

WIPO Patent Application WO/2020/123370

Kind Code:

A3

Abstract:

A method for producing pitch can include: hydroprocessing a challenged feed from a refinery operation to produce a hydroprocessed product; distilling the hydroprocessed product to yield one or more upgraded fractions and a resid fraction; and solvent deasphalting the resid fraction to yield a deasphalted oil stream and a hydroprocessed pitch stream. The resultant pitch can have a micro carbon residue (MCR) of 50 wt% or greater, a solubility in toluene of 95 wt% or greater, and a softening point of 200°C or less. The pitch can optionally be fluxed with a fluxing solvent.
