Alan Howard Pulley 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: 10005971
    Abstract: A process for the hydroprocessing of a gas oil (GO) hydrocarbon feed to provide high yield of a diesel fraction. The process comprises a liquid-full hydrotreating reaction zone followed by a liquid-full hydrocracking reaction zone. A refining zone may be integrated with the hydrocracking reaction zone. Ammonia and other gases formed during the hydrotreatment are removed in a separation step prior to hydrocracking.
    Type: Grant

  • Patent number: 9365782
    Abstract: A process for the hydroprocessing of a low-value light cycle oil (LCO) hydrocarbon feed to provide a high-value diesel-range product. The process comprises a hydrotreatment stage followed by a hydrocracking stage, each of which is conducted under liquid-full reaction conditions wherein substantially all the hydrogen supplied to the hydrotreating and hydrocracking reactions is dissolved in the liquid-phase hydrocarbon feed. Ammonia and optionally other gases formed during hydrotreatment are removed in a separation step prior to hydrocracking. The LCO feed is advantageously converted to diesel in high yield with little loss of hydrocarbon to naphtha.

  • Patent number: 9139782
    Abstract: A process for hydroprocessing hydrocarbons in a combined targeted pretreatment and selective ring-opening unit wherein the targeted pretreatment comprises at least two stages in a single liquid recycle loop. The process operates as a liquid-full process, wherein all of the hydrogen dissolves in the liquid phase. Heavy hydrocarbons and light cycle oils can be converted in the process to provide a liquid product having over 50% in the diesel boiling range, with properties to meet use in low sulfur diesel.
