The Product Heavy Marine Fuel Oil has a maximum sulfur content (ISO 14596 or ISO 8754) less than 0.5 mass %. A process plant for conducting the process for conducting the process is disclosed.
Abstract:
A multi-stage process for transforming a high sulfur ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a core desulfurizing process that produces a Product Heavy Marine Fuel Oil that can be used as a feedstock for subsequent refinery process such as anode grade coking, needle coking and fluid catalytic cracking. The Product Heavy Marine Fuel Oil exhibits multiple properties desirable as a feedstock for those processes including a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process is also disclosed.

Abstract:
The present invention relates to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride comprised of at least one chemical element selected from Groups 3-11 (including the lanthanides, atomic numbers 58 to 71), and at least one chemical element selected from Groups 13-15 from the IUPAC Periodic Table of Elements. These interstitial metal hydrides, their catalysts and processes using these interstitial metal hydrides and catalysts of the present invention improve overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams.
Abstract:
The present invention provides an adsorbent catalytic nanoparticle including a mesoporous silica nanoparticle having at least one adsorbent functional group bound thereto. The adsorbent catalytic nanoparticle also includes at least one catalytic material. In various embodiments, the present invention provides methods of using and making the adsorbent catalytic nanoparticles. In some examples, the adsorbent catalytic nanoparticles can be used to selectively remove fatty acids from feedstocks for biodiesel, and to hydrotreat the separated fatty acids.

A process of hydrodesulphuration of at least one gasoline cut implementing a catalyst comprising, in its oxide form, at least one metal from group VIB and/or at least one metal from group VIII of the periodic table, present in the form of at least one polyoxometalate of the formula (HhXxMmOy)q−, wherein X is an element selected from phosphorus, silicon, boron, nickel and cobalt, M is one or more element(s) selected from molybdenum, tungsten, nickel and cobalt, h is an integer from 0-12, x is an integer from 0-4, m is an integer 5, 6, 7, 8, 9, 10, 11, 12 and/or 18, y is an integer of 17-72 and q is an integer of 1-20, the polyoxometalates being present within a mesostructured silicon oxide matrix having a pore size of 1.5-50 nm and having amorphous walls of thickness 1-30 nm, the catalyst being sulphured before use in the process.
Abstract:
The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value.
Abstract:
A hydrogenation catalyst particularly suitable for hydrogenating oxygenates in a hydrogenation unit of a Fischer-Tropsch plant is disclosed. A preferred embodiment comprises more than 5% and less than 20% nickel based on a wide pore alumina support. The catalyst successfully hydrogenates oxygenates which otherwise tend to poison a catalyst in a hydroconversion unit downstream. Moreover, the temperature at which the unwanted hydrogenolysis of long chain paraffins to methane occurs is higher for one catalyst disclosed herein than a comparable known catalyst. This allows the hydrogenation plant to operate at a higher temperature.
