An integrated process for gasoline production is described. The process includes introducing a feed comprising n-Chydrocarbons into a disproportionation reaction zone in the presence of a disproportionation catalyst to form a disproportionation mixture comprising iso-Cand Cdisproportionation products and unreacted n-Chydrocarbons. An iso-Chydrocarbon 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-Cparaffins. 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-Cstream, and an unreacted n-Chydrocarbon stream. The iso-Cstream is recycled to the alkylation reaction zone, and the unreacted n-Chydrocarbon stream is recycled to the disproportionation reaction zone. The stream comprising the alkylate product is recovered.

Integrated process for gasoline production

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 Cand Cparaffins 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.

Flexible gasoline process using multiple feedstocks

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.

Solids management in slurry hydroprocessing

Apparatuses and methods for deoxygenating a biomass-derived pyrolysis oil are provided herein. 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&#xb0; 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.

Apparatuses and methods for deoxygenating biomass-derived pyrolysis oil

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.

Embodiments of a process for improving a re-refined lube oil stream are provided. The process comprises the steps of introducing a gas stream comprising hydrogen (H) and the re-refined lube oil stream comprising hydroprocessed used lube oil to a hydrogenation reactor that contain Group VIII catalyst. A gas to oil feed ratio rate of from about 30 to about 100 NmH/mis used to introduce the streams to the reactor. The hydroprocessed used lube oil is hydrogenated with the Hin the reactor such that an effluent is formed containing hydrogenated re-refined lube oil having about 2 wt. % or less of aromatics and about 55 wt. % or less of naphthenes. The reactor is operating at a temperature of from about 250 to about 300&#xb0; C.

Methods for making a fuel composition comprising contacting one or more components of a hydroprocessing feedstock, for example both a fatty acid- or triglyceride-containing component and a paraffin-rich component, with hydrogen under catalytic hydroprocessing conditions are disclosed. The methods are effective to upgrade the component(s) and provide a hydroprocessed biofuel. A representative method utilizes a single-stage process in which hydrogen-containing recycle gas is circulated through both a hydrodeoxygenation zone and a hydrocracking zone in series.

This invention relates to a catalyst material, and its method of making and manufacture, useful for a diversity of chemical production processes as well as various emission control processes. More specifically, it relates to a catalyst composition, preferably comprising a metal oxide felt substrate, with one or more functional surface active constituents integrated on and/or in the substrate surface, which can be used in the removal of sulfur and sulfur compounds from hot gases as well as acting to trap solid particulates and trace metals within these hot gases.

A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils, the process providing for sulfur management. The process involves catalytically treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. The hydrocarbon fraction is isomerized to improve cold flow properties. A selective separation such as a hot high pressure hydrogen stripper is used to remove at least the carbon oxides from the first zone effluent before entering the isomerization zone, and to provide liquid recycle to the treating zone at pressure and temperature. A vapor stream is separated from the isomerization effluent and at least carbon dioxide is removed using at least one selective or flexible amine solution absorber. The resulting hydrogen-rich stream is recycled to the deoxygenation reaction zone.
