Patents by Inventor Louis Burns

Louis Burns 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).

  • Integrated hydroprocessing with high productivity catalysts
    Patent number: 8864975
    Abstract: Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for lower temperature operation, which reduces catalyst degradation, while the low density of the catalysts means a corresponding reduction in the amount of metal needed to fill a reactor volume. The methods allow for flexible processing of feedstocks with a variety of wax contents.
    Type: Grant
    Filed: June 13, 2008
    Date of Patent: October 21, 2014
    Assignee: Exxonmobil Research and Engineering Company
    Inventors: Darden Sinclair, Michel Daage, Charles J. Mart, Louis Burns, Timothy L. Hilbert
  • Integrated hydroprocessing with high productivity catalysts
    Patent number: 8864976
    Abstract: Integrated hydroprocessing methods using high activity, low density catalysts are provided. The high activity catalysts allow for blocked operation when processing lube range feedstocks of widely varying characteristics, such as wax content, without having to substantially change the configuration or operating conditions of the process train. Instead, the different feedstocks can be accommodated by varying the reaction temperature in the process train.

  • Preparation of titania and cobalt aluminate catalyst supports and their use in Fischer-Tropsch synthesis
    Publication number: 20070244207
    Abstract: Supports for Fischer-Tropsch catalysts are formed by forming a particulate material from titania, alumina and optionally silica. A cobalt compound is incorporated into the particulate material which then is calcined to convert at least part of the alumina to cobalt aluminate.

  • Integrated plant process to produce high molecular weight basestocks from fischer-tropsch wax
    Publication number: 20050284797
    Abstract: High viscosity lube base oils are produced from syngas by converting syngas under Fischer-Tropsch reaction conditions which are sufficient to produce hydrocarbon products containing greater than 20 lbs of 700° F.+(371° C.+) product per 100 lbs of CO converted. A 450° F.+(232° C.+) cut is separated from the hydrocarbon products and catalytically hydroisomerized and distilled to provide high viscosity lube base oils.
