Abstract: The present invention provides a catalytic pyrolysis process for the production of renewable diesel fuel. The present invention provides a process for preparing renewable diesel fuel, comprising preparing renewable diesel fuel by a) fractionating a mixture comprising renewable aromatics to produce a first fraction boiling at 180° C. to 350° C. at atmospheric conditions, and a fraction boiling below the boiling point of the first fraction, blending at least a portion of the first fraction with at least one distillate cut having lower aromatic content than the first fraction, and b) hydrogenating a blend of the first fraction and distillate cut having lower aromatic content to produce a hydrogenated fraction comprising a renewable diesel fuel.

Abstract: Aspects of the present disclosure relate to methods, systems, and apparatus for efficiently reducing carbon footprints in refining systems and petrochemical processing systems. In one aspect, a plastic powder feedstock is blended into a feedstock of a processing system to re-use plastic and reduce carbon footprints. In one implementation, a method of blending plastics into a processing system includes pulverizing a plastic supply to a plastic stock having a granule size that is within a range of 7 nanometers to nanometers. The method includes separating the plastic stock to remove a portion having a granule size that is outside of the range of 7 nanometers to 10 nanometers and generate a plastic feedstock. The method includes blending the plastic feedstock into a feedstock of the processing system to generate a blended feedstock, and processing the blended feedstock.

Abstract: Embodiments of the present disclosure relate to a method and system for producing syngas containing hydrogen from waste plastic pyrolysis oil. The method and system for producing syngas containing hydrogen from waste plastic pyrolysis oil according to the embodiments of the present disclosure may minimize formation of an ammonium salt (NH4Cl) and may prevent an adhesion phenomenon of impurity particles in a reactor in a refining process of waste plastic pyrolysis oil containing impurities including chlorine and nitrogen. The method and system for producing syngas containing hydrogen according to the present disclosure may have excellent refining efficiency and may implement a long-term operation of a process because a catalyst used in the process is prevented from being deactivated, and may produce lightened and refined hydrocarbons having a low content of impurities and a low content of olefins from waste plastic pyrolysis oil and may thus produce syngas containing hydrogen.
