Processes for the production of a gasoline blend. A C.sub.7 portion of a naphtha stream is first isomerized to increase the branched, iso-paraffins, and then, the isomerized effluent is passed to a dehydrogenation reaction zone. In the dehydrogenation zone, the C.sub.7 saturated hydrocarbons are convert to C.sub.7 olefins. The C.sub.7 olefins have a higher octane number than the C.sub.7 saturated hydrocarbons, and the branched olefins have a higher octane number than the normal olefins. The C.sub.7 olefins can be blended in a gasoline pool. C.sub.5 and C.sub.6 hydrocarbons can be isomerized and dehydrogenated as well, separately or with the C.sub.7 components.

Process scheme configurations are disclosed that enable conversion of crude oil feeds with several processing units in an integrated manner into petrochemicals. The designs utilize minimum capital expenditures to prepare suitable feedstocks for the steam cracker complex. The integrated process for converting crude oil to petrochemical products including olefins and aromatics, and fuel products, includes mixed feed steam cracking and conversion of naphtha to chemical rich reformate. Feeds to the mixed feed steam cracker include light products from hydroprocessing zones within the battery limits, recycle streams from the C3 and C4 olefins recovery steps, and raffinate from a pyrolysis gasoline aromatics extraction zone within the battery limits. Chemical reformate from straight run naphtha streams is used as an additional feed to the aromatics extraction zone and or the mixed feed steam cracker. Feeds to the gas oil steam cracker include hydrotreated gas oil range intermediates from the vacuum gas oil hydroprocessing zone.

Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.
