A method for producing a lubricant base oil includes a first hydrogenation treatment step of bringing a hydrogenation treatment catalyst and a light wax into contact with each other at temperature T.sub.1, and thereby obtaining a first treated oil; a second hydrogenation treatment step of bringing the hydrogenation treatment catalyst and a heavy wax into contact with each other at temperature T.sub.2, and thereby obtaining a second treated oil; and a base oil production step of obtaining a lubricant base oil from a feedstock oil containing at least one selected from the group consisting of the first treated oil and the second treated oil, in which the hydrogenation treatment catalyst is a catalyst obtained by supporting one or more metals selected from the elements of Group 6, Group 8, Group 9, and Group 10 of the Periodic Table of Elements, on an inorganic oxide support.

Method of producing pyrolysis products from a mixed plastics stream along with an associated system for processing mixed plastics. The method includes conducting pyrolysis of a plastic feedstock to produce a stream of plastic pyrolysis oil; feeding the plastic pyrolysis oil to an aromatization unit having an aromatization reactor with an aromatization catalyst disposed therein to generate an aromatics rich stream; and passing the aromatics rich stream to an aromatic recovery complex to separate the aromatics rich stream into a BTX fraction, a gasoline blending fraction, a gas fraction comprising hydrogen and C1-C4 hydrocarbons, and an aromatic bottoms fraction comprising hydrocarbons boiling above 180° C., where the BTX fraction consists of benzene, toluene and mixed xylenes and the gasoline blending fraction comprises aliphatic hydrocarbons with a boiling range from C5 hydrocarbon up to the aromatic bottoms fraction.

The present disclosure relates to methods for preparing aviation fuel component from a feedstock containing fossil hydrotreating feed and a second feed containing esters of fatty acids and rosins, free fatty acids and resin acids. The method includes subjecting the feedstock to hydrotreatment reaction conditions to produce a hydrotreated stream, separating the hydrotreated stream to three fractions from which at least part the highest boiling fraction is subjected to hydrocracking reaction to produce a hydrocracked stream. At least part of the hydrocracked stream is admixed with at least part of the hydrotreated stream, and their admixture is processed further until desired conversion of the feedstock to the aviation fuel component is obtained.

An economic and sustainable process is described herein for zeroing the addition of diluent required in heavy oils transportation by pipelines and by rails. The process reduces both heavy oils characteristics such as: (a) viscosity, (b) density, (c) acidic compounds (TAN), (d) sulfur and (e) olefins generated during the thermal treatment in order to meet stablished criteria for transportation. To prevent premature catalyst deactivation and precipitation, the solids materials in the crude heavy oil are removed first through a physical separation unit, and constitutes a fraction called solid fraction (≤30%), while the solids free fraction or de-solidified fraction (≥70%) of the heavy oil undergoes a thermo-catalytic treatment in a second unit under hydrogen pressure. During this step, both heavy oils properties listed above are reduced. Once produced, the olefins are then saturated by the hydrogen (or additive) present during the reaction yielding a stable treated heavy oil.
