    摘要： An improved process for hydroconverting carbonaceous material wherein the hydroconversion is accomplished in the presence of a sulfide of tin or tin and at least one metal selected from the Group of metals consisting of the Groups IV-B, V-A, VI-A, VII-A and Group VIII-A metals of the Periodic Table of the Elements and in the presence of iodine. The tin and any other metal may be added directly as the sulfide or as a soluble precursor that will either decompose or be converted to the sulfide. The iodine may be added directly as iodine, hydrogen iodine or as a precursor which will decompose to yield either iodine or hydrogen iodide. The hydroconversion is also accomplished in the presence of hydrogen. The tin sulfide when used either alone or in combination with a sulfide of at least one other metal selected from the Group of metals consisting of Groups IV-B, V-A, VI-A, VII-A and VIII-A of the Periodic Table of the Elements when used with iodine surprisingly increases the yield of gasoline boiling range product from the hydroconversion or liquefaction process. When tin sulfide is used in combination with at least one other metal sulfide, the increase in the yield of gasoline boiling range product is even more surprising.

    摘要： This invention relates to novel liquid membrane formulations which are water-in-oil emulsions wherein the oil phase comprises a sulfonated polymer having a backbone which is substantially nonaromatic, for example, less than 10 mole % aromatic, and uses thereof in high temperature liquid membrane processes. The emulsions are useful in liquid membrane water treating processes, especially in water treating processes which are desirably run at high temperatures. In the most preferred embodiment, these compositions are used in a liquid membrane sour water treating process wherein a waste water stream containing ammonium sulfide is contacted with a liquid membrane emulsion, i.e. the emulsions of the instant invention, at conditions whereby ammonia permeates through the external phase of the emulsion into an acidic internal phase wherein it is converted to a nonpermeable form, e.g. ammonium ion, while H.sub.2 S is continuously stripped out of the waste water solution by means of an inert gas, e.g. steam. Processes of this sort are most effectivey carried out at temperatures greater than 80.degree. C. wherein the emulsions of the instant invention have excellent stability.

    摘要： Contacting deactivated hydrodesulfurization catalyst, such as Co-Mo supported on alumina, with a heteropoly acid, such as molybdophosphoric acid or tungstosilicic acid, in pH range of about 1 to 3 and temperature range of about 20.degree. to 80.degree. C., results, before any coke is burned off the catalyst, in selective abstraction of vanadium and nickel, removal of sulfur, increase in surface area, and increase in pore volume of the catalyst. Subsequent cobalt doping of demetallized catalyst followed by calcination promotes decoking, additional sulfur removal and additional increase in surface area and pore volume. The process results in substantially complete regeneration of catalytic activity.

    摘要： The instant invention relates to novel liquid membrane formulations, i.e., emulsions, which comprise an aqueous interior phase and a water-immiscible exterior phase; said water-immiscible exterior phase comprising an ethylene vinyl acetate copolymer and a solvent for this polymer. These compositions may additionally contain a water insoluble surfactant to stabilize the emulsions. In the most preferred embodiment, the aqueous interior phase comprises a strong acid, for example from about 1 to 10 percent by weight sulfuric acid. These emulsions are useful in liquid membrane processes for the separation of dissolved components from aqueous solution. Emulsions of the instant invention are characterized as showing very low swelling when contacted with aqueous solutions, especially at higher temperatures and thus are especially effective for use in the treatment of sour water feed streams by the liquid membrane technique.
