Joseph P. Matula 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).

  • Once-through coking with hydrotreating and fluid catalytic cracking
    Patent number: 4839023
    Abstract: Disclosed is a process for converting heavy hydrocarbonaceous feedstock to more valuable products. The feedstock is introduced into a coking unit containing a coking zone and a scrubbing zone. The bottoms fraction from the scrubbing zone is passed through a microfiltration unit, thus removing fine coke particles which are recycled to the coking zone. The substantially solids-free filtrate is hydrotreated, then passed to a catalytic cracking unit.
    Type: Grant
    Filed: September 16, 1987
    Date of Patent: June 13, 1989
    Assignee: Exxon Research and Engineering Company
    Inventors: Francis X. Mayer, William E. Lewis, Joseph P. Matula, David W. Staubs
  • Once-through coking with solids recycle
    Patent number: 4834864
    Abstract: Disclosed is a process wherein a scrubber bottom stream from a fluid coker is departiculated by passing it through a microfiltration system. The substantially solids-free filtrate is then upgraded by hydrotreating.
    Type: Grant

  • Fluid coking and gasification process
    Patent number: 4331529
    Abstract: An integrated fluid coking and gasification process is provided in which a portion of the coke is gasified in a first gasification zone in the presence of an oxygen-containing gas to produce a hot gas and hot coke. A portion of the resulting hot coke is gasified in a second gasification zone in the presence of steam to produce a gas comprising hydrogen and carbon monoxide, which is suitable, after conventional shift and clean up, for use as synthesis gas.

  • Fluid coking process
    Patent number: 4057487
    Abstract: A hydrocarbonaceous oil is introduced to a quench and scrubbing zone mounted on a fluid coking reactor. Heat from the coker vapor product vaporizes a portion of the hydrocarbonaceous oil. The unvaporized portion of the oil is used to quench and scrub the coker vapor product. The bottoms fraction of the quench and scrubbing zone is passed to a vacuum distillation zone to recover a heavy oil fraction and to produce a vacuum residuum for use as coker feed.
