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.

Abstract: The present invention relates to a method for producing carbon nanoparticles employing heavy petroleum as a carbon precursor, obtained from decant oil, by using the technique of chemical vapor deposition (CVD), and optionally by using an organometallic catalyst that is soluble in the carbon precursor. The main feature of the method according to the invention is that the precursor is vaporized in a controlled manner so as to provide pulses of vapor of constant composition inside a tubular furnace which can be arranged in a vertical position for the continuous production of nanomaterials or in a horizontal position for batch production.

Abstract: The present invention relates to a method for producing carbon nanoparticles from heavy petroleum fractions as the carbon source (precursor), particularly aromatic oil residue (RARO) by chemical vapor deposition (CVD), and optionally by using an organometallic catalyst that is soluble in the precursor. The main feature of the method according to the invention is that the precursor is evaporated in a controlled manner so as to provide a pulse supply of precursor having a constant composition to the inside of a tubular furnace which can be arranged in a vertical position for the continuous production of nanomaterials or in a horizontal position for batch production.

Abstract: This invention describes a process for the distillation of decanted oil to improve the efficiency of the production of pitches having excellent physical and chemical properties through the development of a distillation process which basically comprises the introduction of a stage of condensation of light volatile compounds derived from distillation of the decanted oil, causing these light compounds to be recycled to the hot zone of the still and react with the raw material acting as a solvent phase which has a lower viscosity than the reaction system, within a particular temperature range and for a particular time.
