The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. Certain embodiments additionally comprise mixing at least a portion of the two effluents and contacting with an oligomerization catalyst to provide enhanced yields of aliphatic hydrocarbons that possess the characteristics of a blend component of a liquid transportation fuel or other value-added chemical products.

The present disclosure provides petrochemical processing methods and systems, including ethylene conversion processes and systems, for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compounds, with reduced amount of unsaturated hydrocarbons.

Embodiments disclosed herein related to processes and systems for alkane aromatization. In some embodiments, the process includes merging a benzene-containing stream into an ethane containing stream to form a feed stream. The feed stream has at least 5 wt. % benzene based on the total weight of the feed stream. In addition, the process includes contacting the feed stream with an aromatization catalyst to produce an effluent stream comprising C.sub.7+ aromatic hydrocarbons. Less than 5 wt. % net benzene is produced during the contacting, based on a total weight of the feed stream.

The present disclosure provides a method for generating higher hydrocarbon(s) from a stream comprising compounds with two or more carbon atoms (C.sub.2+), comprising introducing methane and an oxidant (e.g., O.sub.2) into an oxidative coupling of methane (OCM) reactor that has been retrofitted into a system comprising an ethylene-to-liquids (ETL) reactor. The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C.sub.2+ compounds. The first product stream can then be directed to a pressure swing adsorption (PSA) unit that recovers at least a portion of the C.sub.2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C.sub.2+ compounds. The second product stream can then be directed to the ETL reactor. The higher hydrocarbon(s) can then be generated from the at least the portion of the C.sub.2+ compounds in the ETL reactor.

A method for making an alkyl cyclobutane fuel, which includes obtaining a solution of at least one alpha olefin. A catalyst is added to the solution, thereby generating a mixture of dimers. The mixture is hydrogenated, thereby converting the dimers to hydrogenated dimers. The mixture is purified to produce an alkyl cyclobutane fuel.

Systems and methods for processing plastic derived pyrolysis oil are disclosed. A plastic derived pyrolysis oil and/or plastic are processed in a catalytic cracking unit and/or a thermal cracking unit under reaction conditions sufficient to produce a gaseous stream comprising propylene and a liquid stream. The liquid stream is further processed to produce additional propylene.
