    摘要: The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which said process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime.

    摘要: Improved processes and catalysts are described for the conversion of oxygenate-containing olefinic Fischer Tropsch naphtha into aromatics. This involves removal of the oxygenates without complete saturation of the olefins followed by aromatization of the oxygenate-depleted olefinic naphtha preferably over a catalyst that is tolerant to oxygenates.

    摘要: The present invention is a multistage reforming process to produce high octane product from naphtha boiling range feed. In the process, a effluent product from a penultimate reforming stage is separated into at least a first stream and a second stream by boiling point. The lower boiling of the two streams is further reformed in a final reforming stage over a medium pore molecular sieve catalyst.

    摘要: A process for preparing a C4- product stream and a C6+ product stream is disclosed. The process involves contacting a C5 containing paraffinic feedstock with a catalyst that includes a hydrogenation/dehydrogenation catalyst and an olefin metathesis catalyst under conditions which dehydrogenate the paraffins to olefins. The olefins are then metathesized and rehydrogenated to provide a product stream. A C4- fraction and a C6+ fraction can each be isolated from the product stream. The C4- fraction can be used, for example, in an alkylation reaction to provide compounds useful in gasoline compositions. Unconverted C5 paraffins can be recycled. The C6+ fraction can be used, for example, as solvents. Alternatively, they can be isomerized to form gasoline additives, or can be converted to aromatic compounds via reforming, for example, using conventional reforming techniques, preferably using the AROMAX™ process or traditional rheniforming conditions.
