The present application generally relates to the introduction of a renewable fuel oil as a feedstock into refinery systems or field upgrading equipment. For example, the present application is directed to methods of introducing a liquid thermally produced from biomass into a petroleum conversion unit; for example, a refinery fluid catalytic cracker (FCC), a coker, a field upgrader system, a hydrocracker, and/or hydrotreating unit; for co-processing with petroleum fractions, petroleum fraction reactants, and/or petroleum fraction feedstocks and the products, e.g., fuels, and uses and value of the products resulting therefrom.

A catalytic cracking system in which liquid hydrocarbon and bio-oil are directed into a reactor riser of a fluid catalytic cracking unit by separate feed spray nozzle assemblies. To protect liquid bio-oil directed through the liquid bio-oil feed nozzle assembly from high temperature degradation, an insulating layer is provided between a central bio-oil feed tube in a concentrically surrounding atomizing gas passageway. Cooling channels also may be provided in the spray tip of the bio-oil feed nozzle assembly.

Methods and a system for manufacturing a base stock from an ethanol stream are provided. An example method includes dehydrating an ethanol stream to form an impure ethylene stream, recovering an ethylene stream from the impure ethylene stream, and oligomerizing the ethylene stream to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and blended with the ethylene stream prior to the oligomerization. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. The hydro-processed stream is distilled to form the base stock.

A method comprising of converting an oxygenate feed stream stock to a hydrocarbon product stream having substantially no detectable solid content can include conveying the oxygenate feed stream stock through a fluidized catalyst bed comprising catalyst particles to convert the oxygenate feedstock to the product stream comprising catalyst particles and a hydrocarbon selected from the group consisting of a C.sub.5+ gasoline, an olefin, an aromatic, and combinations thereof; and conveying the product stream through a plurality of filter units comprising filter medium to generate a filtered product stream having substantially no detectable solid material, wherein the filter medium comprises a metal alloy, a sintered metal alloy, or a combination thereof.

A process for producing liquid hydrocarbon products from a biomass-containing feedstock and/or a biomass-derived feedstock is provided. The process comprises: a) contacting the feedstock with a hydropyrolysis catalyst composition and molecular hydrogen in a hydropyrolysis reactor vessel to produce a product stream comprising a deoxygenated hydrocarbon product, H.sub.2O, H.sub.2, CO.sub.2, CO, C.sub.1-C.sub.3 gases, char and catalyst fines; b) removing char and catalyst fines from said product stream; c) cooling the remaining product stream to a temperature of no more than 300 C.; and d) hydroconverting all or a portion of said deoxygenated hydrocarbon product in a hydroconversion reactor in the presence of one or more catalyst compositions suitable for the aromatic saturation of the deoxygenated hydrocarbon product and of the H.sub.2O, CO.sub.2, CO, H.sub.2, and C.sub.1-C.sub.3 gas generated in step a), to produce a product comprising C.sub.4+ hydrocarbon product, H.sub.2O, CO, CO.sub.2, and C.sub.1-C.sub.3 gases.

The invention provides a catalyst system and method for the deoxygenation of hydrocarbons, such as bio-oil, using a sulphide-sulfate or an oxide-carbonate (LDH) system. The invention extends to a pyrolysis process of a carbonaceous bio-mass wherein a first combustion zone is carried out in one or more combustion fluidised beds in which a particulate material including chemically looping deoxygenation catalyst particles is fluidised and heated, and a second pyrolysis zone carried out in one or more pyrolysis fluidised beds in which the hot particles, including the catalyst particles, heated in the combustion zone are used for pyrolysis of the bio-mass, said combustion zone being operated at a temperature of from 250 C. to 1100 C., typically around 900 C., and the pyrolysis zone being operated at a temperature of from 250 C. to 900 C., typically 450 C. to 600 C., said catalyst particles being oxygenated in the pyrolysis zone in the presence of oxygenates in the pyrolysis oil and regenerated in the combustion zone either by calcining to drive off the carbon oxides, such as CO.sub.2, or by reduction to its form which is active for deoxygenation of the pyrolysis oil.

The invention relates to a process that comprises dehydration of by-products from ethanol production from sugar cane, by fluidized bed catalytic cracking, for obtaining a renewable hydrocarbon stream, preferably consisting primarily of olefins with 5 carbon atoms, for use in gasolines, and to the and to the hydrocarbon stream and gasoline formulations thus obtained.

Systems and methods are provided for conversion of oxygenate-containing feeds to a hydrocarbon effluent that includes a naphtha boiling range portion with an increased research octane number and/or increased octane rating. The conditions for converting the oxygenate-containing feed can correspond to conversion conditions for fluidized bed operation and/or moving bed operation, with a low acidity catalyst that also includes phosphorus to improve the hydrogen transfer rate relative to the expected hydrogen transfer rate for a low acidity catalyst. In addition to providing a naphtha fraction with an improved research octane number and/or octane rating, the amount of durene in the naphtha fraction can be reduced or minimized.
