Abstract
Pitch is obtained, in a reactor configured for the atmospheric process, from a feedstock of oil hydrocarbons consisting of a feedstock of decanted oil. In the process, the feedstock is subjected to heating stages in reflux and distillation conditions with removal of volatile products generated, wherein the gaseous products are eliminated at each stage and the successively generated residual products comprise a final residue recovered as a predominantly isotropic pitch.
