Abstract: In a first stage of a methane conversion system, at least some methane (CH4) in an input gas flow stream can be converted into C2 hydrocarbons, hydrogen gas (H2), and aromatics to provide a first processed stream. The conversion can be direct non-oxidative methane conversion (DNMC). At least some of the aromatics can be removed from the first processed stream to provide a second processed stream. In a second stage of the methane conversion system, at least some of the H2 can be removed from the second processed stream to provide a recycle stream. The recycle stream can be returned to the first stage of the methane conversion system for further conversion of methane and removal of aromatics and H2 products.

Abstract: A process for cracking olefins to produce propylene, ethylene, or both, includes providing a feed stream that includes mixed butenes and contacting the feed stream with a cracking catalyst at reaction conditions that cause at least a portion of the mixed butenes in the feed stream to react to form propylene, ethylene, or both. The cracking catalyst includes zeolite particles formed from shape selective zeolite particles and an alumina binder. The cracking catalyst further includes at least one transition metal oxide impregnated onto the zeolite particles, where the at least one transition metal oxide can be iron oxide, nickel oxide, or a combinations of these. The cracking catalyst with the iron oxide, nickel oxide, or both increases conversion of mixed butenes to propylene, ethylene, or both alone or in combination with a metathesis upstream of the cracking catalyst, as compared to conventional cracking catalysts.

Abstract: A method for carbon dioxide direct hydrogenation to gasoline-range hydrocarbons is provided in this invention. Under the reaction conditions of 250-450° C., 0.01-10.0 MPa, 500-50000 mL/(h·gcat) of feedstocks, 0.5-8 molar ratio of H2 to CO2, the mixture of carbon dioxide and hydrogen may be directly converted to gasoline-range hydrocarbons over a multifunctional hybrid catalyst. The multifunctional hybrid catalyst comprises: iron-based catalyst for carbon dioxide hydrogenation as the first component, one, two or more of zeolites optionally modified by metal as the second component. In this method, a per-pass conversion of CO2 may achieve more than 33%, the methane selectivity in the hydrocarbon products is less than 8%, the selectivity of gasoline-range hydrocarbons with carbon numbers from 5 to 11 in the hydrocarbon products is more than 70%. The obtained gasoline-range hydrocarbons exhibit high octane number due to its composition comprising isoparaffins and aromatics as the major components.

Abstract: The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM1) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S1) which originates from a steamcracking process. The hydrocarbon mixture (HM1) obtained from this stream (S1) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S1), and (HM1) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM1), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM1). In addition, depending on the presence of other components of (HM1), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM2) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.
