A process for purification a hydrocarbon stream including: (a) Providing a hydrocarbon stream having a diene value of at least 1.0, a bromine number of at least 5 g and containing at least 10 wt % of pyrolysis plastic oil; b) contacting the effluent obtained in step a) with a silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports, and/or silica gel, or any mixture thereof; c) performing a first hydrotreating step; d) contacting the effluent obtained in step c) with silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminium oxide, molecular sieves, alkaline oxide and/or porous supports and silica gel, or any mixture thereof; e) performing a second hydrotreating step; and f) recovering a purified hydrocarbon stream.

A desulfurization system has an oxidation process unit, and a multi-stage, liquid-liquid extraction unit in series with the oxidation process unit. The multi-stage, liquid-liquid extraction unit spits a fuel input from the oxidation process unit into a desulfurized fuel that is output for use, and a by-product. A solvent/sulfur/hydrocarbon separation process unit receives the by-product from the multi-stage, liquid-liquid extraction unit.

Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

A process for the purification of a hydrocarbon stream including: (a) Providing a hydrocarbon stream having a diene value of at least 1.0 and a bromine number of at least 5 gBr2/100 g and containing pyrolysis plastic oil; (b) Optionally contact the hydrocarbon stream obtained in step (a) with a silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminum oxide, molecular sieves, alkaline oxide and/or porous supports and silica gel, or any mixture thereof; (c) Heating the stream obtained in step a) or b) followed by a mixing of the heated stream with a second diluent heated at a temperature of at least 300° C. preferably at least 330° C.; (d) performing an hydroprocessing step at a temperature of at least 250° C. in the presence of H2; and (e) recovering a purified hydrocarbon stream.

An integrated process that is operated to create both a higher value pipelineable crude and a higher value carbon fiber product from a lower value common heavy hydrocarbon feedstock where the feedstock is processed in a thermal reactor followed by a solvent deasphalting unit with the liquids being gathered and processed to reduce olefins for pipeline transport and the solids are processed to generate a marketable carbon fiber product with any gases generated throughout the entire process reused in the process or sold.

The present disclosure relates to a method for upgrading liquefied waste plastics, the method including a step (A) of providing liquefied waste plastics (LWP) material, optionally a step (B) of pre-treating at least part of the liquefied waste plastics (LWP) material to produce a pre-treated liquefied waste plastics (LWP) material, a step (C) of blending the liquefied waste plastics (LWP) material and/or the pre-treated liquefied waste plastics (LWP) material with a highly paraffinic material to obtain a cracker feed such that the cracker feed meets the requirements for chlorine content and olefins content of the steam cracker, and a step (D) of steam cracking the cracker feed in a steam cracker to obtain a cracker product.

There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.
