  • Patent number: 11542442
    Abstract: Hydrocracked bottoms fractions are treated to separate HPNA compounds and/or HPNA precursor compounds and produce a reduced-HPNA hydrocracked bottoms fraction effective for recycle. A process for separation of HPNA and/or HPNA precursor compounds from a hydrocracked bottoms fraction of a hydroprocessing reaction effluent comprises contacting the hydrocracked bottoms fraction with heteropoly acid compounds to promote adsorption of HPNAs onto the heteropoly acids and to produce a heteropoly acid treated hydrocracked bottoms fraction, that is recycled within the hydrocracking operation.

  • Publication number: 20220389334
    Abstract: An integrated process for conversion of a hydrocarbon stream comprising light naphtha to enhanced value products. The process includes passing the hydrocarbon stream through the first reactor, the first reactor being an isomerization reactor with an isomerization catalyst disposed therein to generate an isomerate stream comprising at least 20% by weight iso-paraffins. The process further includes passing the isomerate from the first reactor through a second reactor, the second reactor being an aromatization reactor with an aromatization catalyst disposed therein to generate an aromatic rich stream. The process finally includes passing the aromatic rich stream to an aromatic recovery complex to separate the aromatic rich stream into an aromatic fraction, a raffinate fraction comprising unconverted paraffins, and an aromatic bottoms fraction comprising C9+ hydrocarbons, where the aromatic fraction comprises benzene, toluene and mixed xylenes. An associated system for performing the process is also provided.
