Abstract: In accordance with one or more embodiments of the present disclosure, a method for producing aromatic compounds from pyrolysis gasoline comprising C5-C6 non-aromatic hydrocarbons includes aromatizing the pyrolysis gasoline in an aromatization unit, thereby converting the C5-C6 non-aromatic hydrocarbons to a first stream comprising benzene-toluene-xylenes (BTX); hydrotreating the first stream comprising BTX in a selective hydrotreatment unit, thereby producing a de-olefinated stream comprising BTX hydrodealkylating and transalkylating the de-olefinated stream comprising BTX in a hydrodealkylation-transalkylation unit, thereby producing a second stream comprising BTX, the second stream comprising BTX having a greater amount of benzene and xylenes than the first stream comprising BTX; and processing the second stream comprising BTX in an aromatics recovery complex, thereby producing the aromatic compounds from the pyrolysis gasoline, the aromatic compounds comprising benzene, toluene, and xylenes.

Abstract: A method for producing a linear alkylbenzene product from a bio-renewable feedstock having a mixture of naturally-derived hydrocarbons includes separating the mixture of naturally-derived hydrocarbons into a naphtha portion and a distillate portion, reforming the naphtha portion, and using a high purity aromatics recovery process on the reformed naphtha portion to produce benzene. The method further includes separating a normal paraffins portion from the distillate portion and dehydrogenating the normal paraffins portion to produce mono-olefins. Still further, the method includes reacting the benzene and the mono-olefins to produce the linear alkylbenzene product.

Abstract: Processes and apparatuses for preparing aromatic compounds are provided. In an embodiment, a process of preparing aromatic compounds includes providing a heavy reformate stream including C7 hydrocarbons, xylenes, styrene, and compounds having more than 8 carbon atoms. The xylenes and styrene are separated from the compounds that have more than 8 carbon atoms in the heavy reformate stream to form a mixed xylene stream including the xylenes and styrene and a C9+ stream including compounds with less volatility than C8 aromatics. The styrene within the mixed xylene stream is selectively hydrogenated to form a hydrogenated xylene stream including xylenes and ethylbenzene. At least some of the xylenes are separated from the ethylbenzene in the hydrogenated xylene stream to form a C8 raffinate stream including the ethylbenzene and a xylene product stream including one or more xylene species.
