  • Patent number: 12195679
    Abstract: An hydroconverted effluent composition is provided, along with systems and methods for making such a composition. The hydroconverted effluent composition can have an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the hydroconverted effluent composition, the composition can include unexpectedly high contents of nitrogen.

  • Patent number: 11981870
    Abstract: Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.

  • Patent number: 11767477
    Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport.

  • Patent number: 11760942
    Abstract: An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593° C. (1100° F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

  • Publication number: 20230098592
    Abstract: This application relates to renewable diesel production and to production of renewable naphtha in a renewable diesel unit. Disclosed herein is an example of a method of renewable diesel production. Examples embodiments of the method may include hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock; contacting at least a portion of the hydrotreated biofeedstock with a dewaxing catalyst to produce a renewable diesel product and a renewable naphtha product; separating the renewable diesel product and the renewable naphtha product in a product splitter; and monitoring an octane number of the renewable naphtha product with an analyzer.

  • Patent number: 11225611
    Abstract: Disclose is an online analyzer to monitor conversion of a biofeedstock in a first hydrotreating stage to avoid catalyst poisoning in a subsequent stage. An example method of processing a biofeedstock may comprise hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock. The method may further comprise monitoring conversion of the biofeedstock in the hydrotreating with an online analyzer.
