The apparatus produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and hydroisomerization to improve cold flow properties. Heavy diesel can be hydrocracked to jet fuel range material or further hydroisomerized to increase its value lower its freeze point while light diesel may be taken as a motor fuel.

Process for producing jet fuel from a biorenewable feed

A new catalyst hydroisomerizes C18 paraffins from fatty acids to a high degree to produce a composition with acceptable freeze point which retains 18 carbon atoms in the hydrocarbon molecule for jet fuel. We have discovered a fuel composition comprising at least 14 wt % hydrocarbon molecules having at least 18 carbon atoms and a freeze point not higher than −40° C. The composition also may exhibit a exhibiting a final boiling point of no more than 300° C. The hydroisomerization process can be once through or a portion of the product diesel stream may be selectively hydrocracked or recycled to hydroisomerization to obtain a fuel composition that meets jet fuel specifications.

A process and apparatus for managing hydrogen sulfide in a refinery is provided. In the process, a hydrogen sulfide stream from said refinery is fed to a sulfur recovery unit to produce sulfur and a sulfur compound stream or to a thermal oxidizer. The sulfur compound stream and the hydrogen sulfide stream are then thermally oxidized to produce a sulfur oxide stream. The sulfur oxide stream is then reacted with an ammonia stream. In aspect, the product of the reaction can be a fertilizer. The ammonia stream can be obtained from stripping the hydrogen sulfide stream.

A process and apparatus for recycling LCO and/or HCO to a hydroprocessing zone to saturate aromatics for cracking in an FCC unit is disclosed. The recycle cracked stream may be recycled to a downstream hydroprocessing zone to avoid a first hydroprocessing zone that is primarily for demetallizing (and desulfurizing) feed to the FCC unit.

Process and apparatus for recycling cracked hydrocarbons

A process and apparatus for two stage hydrocracking saturates aromatics from the first stage hydrocracking unit to prevent production of HPNA's. The saturated HPNA's can be hydrocracked in the second stage to minimize or eliminate purged unconverted oil to approach or obtain maximum conversion. In an aspect, the second stage hydrocracking reactor and hydrotreating reactor may be located in the same vessel.

One exemplary embodiment can be a process for producing a diesel fuel. The process can include providing a hydrocarbon feed to a residue processing unit. Generally, the residue processing unit includes a solvent deasphalting zone, a hydroprocessing zone, and a hydroprocessing fractionation zone. The process can further include recycling at least a portion of an unconverted oil stream from the hydroprocessing fractionation zone, and sending one part of the at least a portion of the recycled unconverted oil stream to the unconverted oil fractionation zone providing a light unconverted oil stream downstream of the solvent deasphalting zone and a heavy unconverted oil stream to the solvent deasphalting zone.

Embodiments of methods for purifying a biomass-derived pyrolysis oil are provided. The method comprises the step of contacting the biomass-derived pyrolysis oil with a first deoxygenating catalyst in the presence of hydrogen at first predetermined hydroprocessing conditions to form a first low-oxygen biomass-derived pyrolysis oil effluent. The low-oxygen biomass-derived pyrolysis oil effluent is contacted with an ionic liquid to remove phenolic compounds, nitrogen compounds and other impurities. This ionic liquid step may be followed by a second deoxygenation step or the deoxygenating may be completed and then followed by the ionic liquid purification step.

A method for producing a linear alkylbenzene product from a bio-renewable feedstock having a mixture of naturally-derived hydrocarbons includes separating the mixture of naturally-derived hydrocarbons into a naphtha portion and a distillate portion, reforming the naphtha portion, and using a high purity aromatics recovery process on the reformed naphtha portion to produce benzene. The method further includes separating a normal paraffins portion from the distillate portion and dehydrogenating the normal paraffins portion to produce mono-olefins. Still further, the method includes reacting the benzene and the mono-olefins to produce the linear alkylbenzene product.

A process for removing a nitrogen compound and a sulfur compound from a hydroprocessed vacuum gas oil feed includes contacting the hydroprocessed vacuum gas oil feed comprising the nitrogen compound and the sulfur compound with a VGO-immiscible phosphonium ionic liquid to produce a hydroprocessed vacuum gas oil and VGO-immiscible phosphonium ionic liquid mixture, and separating the mixture to produce a hydroprocessed vacuum gas oil effluent having a reduced nitrogen compound and sulfur compound content relative to the vacuum gas oil feed. It was found that the amount of the sulfur compound being removed was significantly improved by first removing the nitrogen compounds, especially polar nitrogen compounds.
