Abstract: An integrated process for gasoline production is described. The process includes introducing a feed comprising n-C5 hydrocarbons into a disproportionation reaction zone in the presence of a disproportionation catalyst to form a disproportionation mixture comprising iso-C4 and C6+ disproportionation products and unreacted n-C5 hydrocarbons. An iso-C4 hydrocarbon stream and an olefin feed are introduced into an alkylation reaction zone in the presence of an alkylation catalyst to produce an alkylation mixture comprising alkylate and unreacted iso-C4 paraffins. The disproportionation mixture and the alkylation mixture are combined, and the combined mixture is separated into at least a stream comprising the alkylate product, an iso-C4 stream, and an unreacted n-C5 hydrocarbon stream. The iso-C4 stream is recycled to the alkylation reaction zone, and the unreacted n-C5 hydrocarbon stream is recycled to the disproportionation reaction zone. The stream comprising the alkylate product is recovered.

Abstract: A flexible process for gasoline refineries is described. The process can vary depending on the available feedstock and the desired products. At one time, the process can involve disproportionating pentanes to a product mixture including isobutane and isohexane. At other times, by switching the feedstock and operating conditions, the process can convert a mixture of C4 and C7 paraffins to a low aromatic blendstock with suitable octane and a vapor pressure lower than butanes. The process can be performed in separate stand-alone units operated at different times, or a single unit can be operated according to one process at one time and according to the other process at another time.

Abstract: The recovery of solids, and particularly solid particulates used as catalysts in slurry hydroprocessing, from asphaltene containing hydrocarbons is improved by controlling asphaltene precipitation. The formation of agglomerates of the solid particulates, having an increased diameter, results in the presence of precipitated asphaltenes, possibly due to flocculation. Asphaltene precipitation is controlled by varying process parameters or introducing additional diluent or flush streams that change the polarity of an asphaltene containing liquid product recovered from an effluent of a slurry hydroprocessing reaction zone.

In one example, the method comprises of dividing a feedstock stream into first and second feedstock portions. The feedstock stream comprises the biomass-derived pyrolysis oil and has a temperature of about 60° C. or less. The first feedstock portion is combined with a heated organic liquid stream to form a first heated diluted pyoil feed stream. The first heated diluted pyoil feed stream is contacted with a first deoxygenating catalyst in the presence of hydrogen to form an intermediate low-oxygen pyoil effluent. The second feedstock portion is combined with the intermediate low-oxygen pyoil effluent to form a second heated diluted pyoil feed stream. The second heated diluted pyoil feed stream is contacted with a second deoxygenating catalyst in the presence of hydrogen to form additional low-oxygen pyoil effluent.

Abstract: Fuel compositions exhibiting reduced greenhouse gas (GHG) emissions, based on a lifecycle assessment from the time of cultivation of feedstocks (in the case of plant materials) or extraction of feedstocks (in the case of fossil fuels) required for the compositions (up to and including the ultimate combustion of the fuel composition by the end user) are disclosed. The reduced level of emissions (“carbon footprint”) is achieved by incorporating a pyrolysis derived component having a higher heating value than ethanol and meeting other applicable standards for fossil fuel (e.g., petroleum) derived components conventionally used for the same purpose, such as transportation fuels. Advantageously, fuel compositions comprising pyrolysis derived gasoline can exhibit lower GHG emissions than gasoline derived solely from petroleum, or even conventional blends of petroleum derived gasoline and ethanol.

A vapor stream is separated from the net process effluent and at least carbon dioxide is removed using at least one selective or flexible amine absorber. The resulting hydrogen-rich stream is recycled to the reaction zone.
