A method is provided involving reducing a pressure drop across a hydroprocessing reactor having a reactor feed and producing a hydroprocessing product, where the reactor feed includes a bio-oil feed and a hydrocarbon diluent; and the step of reducing the pressure drop comprises stopping or substantially reducing the bio-oil feed supplied to the reactor and supplying the hydrocarbon diluent to the reactor with a mass flux of at least about 1,000 lb/hr/ft.

Reducing pressure drop buildup in bio-oil hydroprocessing reactors

The present technology generally relates to a method for producing a naphtha product from a biorenewable feedstock. The method includes hydrotreating the biorenewable feedstock to produce a hydrocarbon product stream, hydrocracking hydrocarbons from the hydrocarbon product stream to produce a distribution of cracked hydrocarbons, and separating a biorenewable naphtha fraction from the distribution of cracked hydrocarbons.

Biorenewable naphtha

The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.

A process for producing a hydrocarbon from biomass. A feed stream containing biomass having fatty acids, mono-, di-, and/or triglycerides, and a phosphorus content of between about 1 wppm and about 1,000 wppm is provided. A heated hydrocarbon solvent and a hydrogen-rich gas are provided. The feed stream, the heated hydrocarbon solvent, and the hydrogen-rich gas are combined in the presence of a low activity hydrogenation catalyst. A spent low activity hydrogenation catalyst is recovered at the end of a run wherein the spent low activity hydrogenation catalyst contains at least 3% by weight phosphorus.
