ABSTRACT:
A process for converting cat cracker bottoms to a feedstock suitable for carbon artifact manufacture, especially carbon fiber manufacture, is provided. Basically, the cat cracker bottom is stripped of fractions boiling below about 400.degree. C., catalytically heat soaked at temperatures below about 410.degree. C., and then vacuum stripped to provide a pitch. The pitch is subsequently treated to remove high melting solids, such as ash, coke and catalyst fines.
