    摘要: Methods of making synthetic distillate fuel are described. The methods involve the use of an absorbent bed of molecular sieves which adsorb the n-paraffins from a distillate fuel cut. This allows the distillate fuel true boiling point cut point on the distillation column to increase to a higher temperature to make a distillate fuel which meets all of the synthetic paraffinic kerosene (SPK) or synthetic diesel specifications on distillation as well as the cold flow property specification, such as freeze point for SPK or cloud point, cold filter plugging point and pour point for synthetic diesel. This approach could improve aviation fuel yields by about 5 to about 10% and synthetic diesel yields up to 20%.

    摘要: This invention relates to a process for thermochemically transforming biomass or other oxygenated feedstocks into high quality liquid hydrocarbon fuels. In particular, a catalytic hydropyrolysis reactor, containing a deep bed of fluidized catalyst particles is utilized to accept particles of biomass or other oxygenated feedstocks that are significantly smaller than the particles of catalyst in the fluidized bed. The reactor features an insert or other structure disposed within the reactor vessel that inhibits slugging of the bed and thereby minimizes attrition of the catalyst. Within the bed, the biomass feedstock is converted into a vapor-phase product, containing hydrocarbon molecules and other process vapors, and an entrained solid char product, which is separated from the vapor stream after the vapor stream has been exhausted from the top of the reactor. When the product vapor stream is cooled to ambient temperatures, a significant proportion of the hydrocarbons in the product vapor stream can be recovered as a liquid stream of hydrophobic hydrocarbons, with properties consistent with those of gasoline, kerosene, and diesel fuel. Separate streams of gasoline, kerosene, and diesel fuel may also be obtained, either via selective condensation of each type of fuel, or via later distillation of the combined hydrocarbon liquid.

    摘要: A process has been developed for producing a diesel boiling point range product and an aviation boiling point range product from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction which is then isomerized and selectively cracked to form the diesel boiling point range product and the aviation boiling point range product. A portion of the diesel boiling point range product, aviation boiling point range product, naphtha product, LPG, or any combination thereof can be optionally used as a rectification agent in the selective hot high pressure hydrogen stripper to decrease the amount of product carried in the stripper overhead.

    摘要: The present invention involves a process for processing an acidic biorenewable feedstock comprising olefins, in which the acidic biorenewable feedstock is diluted with a deoxygenated feed to produce a diluted biorenewable feedstock and then is sent through a guard bed comprising a hydroprocessing catalyst to cause the olefins to be saturated with hydrogen and thereby to produce a treated biorenewable feedstock. This treated biorenewable feedstock can then be treated under standard hydroprocessing condition to produce an upgraded feedstock for transportation fuels.

    摘要: A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils and animal oils, fats, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and/or hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel or diesel boiling range fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A portion of the hydrogenated and deoxygenated feedstock is selectively separated and then recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

    摘要: 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.
