Patents by Inventor Daniel J. Pintar

Daniel J. Pintar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10745630
    Abstract: A method of reducing catalyst agglomeration in a slurry hydrocracking zone containing at least two reactors is described. A hydrocarbon feed and a slurry hydrocracking catalyst are contacted in a first reactor to form a first effluent containing slurry hydrocracking reaction products, unreacted hydrocarbon feed, and the slurry hydrocracking catalyst, wherein the slurry hydrocracking catalyst agglomerates. The first effluent and an unsupported hydrogenation catalyst are contacted in a second reactor to form a second effluent containing the slurry hydrocracking reaction products, unreacted hydrocarbon feed, the slurry hydrocracking catalyst, and asphaltene reaction products.
    Type: Grant
    Filed: June 4, 2018
    Date of Patent: August 18, 2020

  • Patent number: 9914891
    Abstract: Methods of maximizing diesel production are describes. The methods include providing a stream of heavy heavy naphtha; and blending the stream of heavy heavy naphtha with a diesel stream from the crude distillation zone to increase diesel production while maintaining the blended diesel stream within a specification for diesel. Various apparatus for maximizing diesel production are also described.

  • Patent number: 9567536
    Abstract: An integrated slurry hydrocracking process and apparatus are described. The process includes introducing heavy residual hydrocarbon oil and a hydrogen stream into a slurry hydrocracking zone. The hydrocarbon feed is cracked to form a slurry hydrocracking effluent. At least a portion of the shiny hydrocracking effluent is introduced to a distillate hydrotreater along with make-up hydrogen. The slurry hydrocracking effluent is hydrotreated to form a hydrotreated effluent. The hydrotreated effluent is separated into a liquid stream and a gas stream containing hydrogen. The gas stream containing the hydrogen is recycled to the slurry hydrocracking zone forming the hydrogen stream introduced into the slurry hydrocracking zone.
