  • Patent number: 10041011
    Abstract: A process for recovering hydrocarbons from a slurry hydrocracking reactor. The hydrocarbons are recovered by taking a drag stream of the slurry in the reactor. After separating lighter hydrocarbons in a separation zone, the heavier hydrocarbons can be processed in a deashing zone, with a vacuum column bottoms from a separation of the effluent stream recovered from the reactor. The deashing zone can recover the heavier hydrocarbons in a deashed pitch. Additionally, a VGO rich stream from the deashing zone may be recycled back to the reactor.

  • Patent number: 10041004
    Abstract: A process for de-ashing pitch. The pitch from a slurry hydrocracking process is mixed with a solvent. The mixture is separated into solvent and soluble materials and insoluble materials. The insoluble materials can be dried to recover solvent which may be recycled. The solvent and soluble materials are separated. The solvent may be recovered and recycled. Hi-Sol 15 may be the solvent. Additionally, CSO may be the solvent and a portion thereof may be used with the de-ashed pitch to make an asphalt binder.

  • Patent number: 9777226
    Abstract: Methods and systems for slurry hydrocracking with reduced feed bypass and methods for modulating an amount of toluene insoluble material present in a slurry hydrocracking reactor are provided. An exemplary slurry hydrocracking method comprises the steps of: combining a hydrocarbon feed and a slurry hydrocracking catalyst or catalyst precursor to generate a slurry hydrocracking feed; introducing the slurry hydrocracking feed to a slurry hydrocracking reactor under hydrocracking conditions suitable to generate a first product stream; drawing a drag stream from the slurry hydrocracking reactor, the drag stream comprising a hydrocarbon, mesophase material, and solid catalyst particles; separating the drag stream into a first separated stream and a recycle stream, with the first separated stream comprising mesophase material and solid catalyst particles, and the recycle stream comprising the hydrocarbon; and directing the recycle stream into the slurry hydrocracking reactor.

  • Patent number: 8691080
    Abstract: One exemplary embodiment can include a slurry hydrocracking process. The process can include combining one or more hydrocarbons and a slurry hydrocracking catalyst as a feed to a slurry hydrocracking reaction zone, fractionating an effluent from the slurry hydrocracking reaction zone, separating the pitch from at least a portion of the slurry hydrocracking catalyst, and recycling the suspension to the slurry hydrocracking reaction zone. The slurry hydrocracking catalyst may include a support. Fractionating the effluent may provide a light vacuum gas oil, a heavy vacuum gas oil, and a mixture comprising a pitch and the slurry hydrocracking catalyst. Generally, the separated slurry hydrocracking catalyst is comprised in a suspension.

  • Patent number: 8617384
    Abstract: A process for maximizing p-xylene production begins by producing a naphtha fraction and a light cycle oil fraction from a fluid catalytic cracking zone. The gasoline and light cycle oil fractions are combined and hydrotreated to produce a hydrotreated product. Fractionation of the hydrotreated product in a fractionation zone makes a light ends cut, a naphtha cut, a hydrocracker feed and an unconverted oil fraction. The hydrocracker feed is sent to a hydrocracking zone to make a hydrocracker product, which is then recycled back to the fractionation zone, feeding the hydrocracker product above an outlet for the hydrocracker feed, but below an outlet for the naphtha cut. The naphtha cut goes to a dehydrogenation zone where hydrogen is removed to make aromatics from naphthenes to make a dehydrogenated naphtha. The dehydrogenated naphtha is fed to an aromatics recovery unit to recover p-xylene and other aromatics.

  • Patent number: 8608941
    Abstract: A reforming process includes integrating catalytic cracking product naphtha dehydrogenation and naphtha from a hydrocracking zone and feeding them to a dehydrogenation zone. The dehydrogenation zone includes a first portion of reforming catalyst from a catalyst regenerator that moves downward through the dehydrogenation zone. A product stream from the dehydrogenation zone flows to an aromatics unit and is separated into an aromatic-rich extract and a raffinate. Straight run naphtha and the raffinate are introduced to a first reforming zone that includes a second portion of reforming catalyst. The reforming catalyst moves through the first reforming zone then is removed from the bottom of each of the first reforming zone and the dehydrogenation zone and is fed to a second reforming zone. An effluent from the first reforming zone is fed to a plurality of reforming zones. The reforming catalyst moves downward through the multiple reforming zones then to a regenerator.

Fractionation of the hydrotreated product makes a hydrocracker feed that is sent to a hydrocracking zone to make a naphtha cut and a hydrocracker product. The hydrocracker product is recycled back to the fractionation zone, and the naphtha cut is dehydrogenated in a dehydrogenation zone to make aromatics. Reforming catalyst from a catalyst regenerator moves downward through the dehydrogenation zone. Straight run naphtha and raffinate from the aromatics unit are introduced to an additional series of reforming zones. The reforming catalyst moves in parallel through the first reforming zone and the dehydrogenation zones, then is combined for entry to the second and subsequent reforming zones prior to regeneration.
