Raffinates from catalytic gasoil as feedstocks for the production of technical carbon

Abstract

Investigates desorbed raffinates, obtained in the adsorption treatment of CGO, as feedstocks for technical carbon production. Explains that the CGO was produced in a type 1A/1M commercial unit operating on zeolitic catalyst with a heavy distillate feedstock from mixed medium-sulfur crudes of the Ural district. Finds that the yield of technical carbon from the desorbed raffinate is 3-4% higher than from the traditional feedstock (e.g. the solvent extract). Notes that the technical carbon obtained from the experimental feed is characterized by a considerably higher oil number in comparison with the carbon produced from the standard feed, and the specific surface areas are quite similar. Points out that the technical carbon from the desorbed raffinate completely meets the requirements for high-dispersity, highly structurized technical carbon in grades PM-75V and PM-100V. Recommends the desorbed raffinate from adsorptive treating of heavy CGO as a feedstock for the production of high-dispersity technical carbon, with either normal structure or a higher level of structure.
