Targeted Desulfurization Apparatus Integrating Oxidative Desulfurization And Hydrodesulfurization To Produce Diesel Fuel Having An Ultra-Low Level Of Organosulfur Compounds
United States Patent Application 20160208179
Saudi Aramco: Bourane; Abdennour ; et al. July 21, 2016
Abstract
Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boil at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with an oxidizing agent and an active metal catalyst in an oxidation reaction zone to convert the refractory organosulfur compounds to oxidized organosulfur compounds. The oxidized organosulfur compounds are removed, producing a stream containing an ultra-low level of organosulfur compounds. The two streams can be combined to obtain a full range hydrocarbon product having an ultra-low level of organosulfur compounds.

Adsorptive Desulfurization
United States Patent Application 20160175806
University of Connecticut: Suib; Steven L. ; et al. June 23, 2016
Abstract
The disclosure relates to a method for removing sulfur-containing compounds from a fluid. The method involves adding manganese oxide to the fluid; doping the manganese oxide in situ with iron, cobalt, or combinations thereof to give a doped manganese oxide adsorbent; and contacting the fluid with a selected amount of the doped manganese oxide adsorbent and at a selected temperature and pressure sufficient for the doped manganese oxide adsorbent to preferentially adsorb the sulfur-containing compounds in the fluid. The disclosure also relates to a process for preparing a doped manganese oxide adsorbent, and a doped manganese oxide adsorbent prepared by the process. The disclosure further relates to a method for tuning structural properties (e.g., surface area, pore size and pore volume) of a doped manganese oxide adsorbent.

Sulfur-resistant Catalyst for Aromatics Saturated Hydrogenation and Preparation Method Thereof
United States Patent Application 20160167017
PetroChina: Yang; Xiaodong ; et al. June 16, 2016
Abstract
The present invention relates to a method for preparing a sulfur-resistant catalyst for aromatics saturated hydrogenation, comprising the steps of: preparing noble metal impregnation solutions from a noble metal and deionized water or an acid solution; impregnating a carrier with the impregnation solutions sequentially from high to low concentrations by incipient impregnation; homogenizing, drying, and calcinating to obtain the sulfur-resistant catalyst for aromatics saturated hydrogenation. The catalyst for aromatics saturated hydrogenation prepared by the method according to the present invention is primarily used in processing low-sulfur and high-aromatics light distillate, middle distillate, atmospheric gas oil, and vacuum gas oil. The method according to the present invention is advantageous in that the catalyst for aromatics saturated hydrogenation exhibits good hydrofining performance, superior aromatics saturation performance, high liquid yield of products, as well as excellent desulfurization and sulfur-resistance, and the catalyst has remarkable effects in use and a great prospect of application.
