    摘要: A method for assembling patterned crystalline arrays of colloidal particles using ultraviolet illumination of an optically-sensitive semiconducting anode while using the anode to apply an electronic field to the colloidal particles. The ultraviolet illumination increases current density, and consequently, the flow of the colloidal particles. As a result, colloidal particles can be caused to migrate from non-illuminated areas of the anode to illuminated areas of the anode. Selective illumination of the anode can also be used to permanently affix colloidal crystals to illuminated areas of the anode while not affixing them to non-illuminated areas of the anode.

    摘要: A process is set forth for reacting impure toluene to obtain benzene, toluene and a para-rich xylene stream, which are substantially free of close-boiling non-aromatics. The impure toluene comprises at least 70 wt % toluene and between about 0.2 wt % and about 5 wt % close-boiling non-aromatics. The process may also comprise aromatizing a naphtha over a non-acidic catalyst. The impure toluene from the aromatization step is passed over an acidic intermediate pore zeolite to produce a para-rich xylene stream and chemically pure benzene.

    摘要: A catalyst composition and a process for converting a hydrocarbon stream such as, for example, gasoline to C6 to C8 aromatic hydrocarbons such as toluene and xylenes are disclosed. The catalyst composition includes an alumina, a silica, and a metal wherein the weight ratio of aluminum to silicon is in the range of from about 0.002:1 to about 0.6:1. The process includes contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to a C6 to C8 aromatic hydrocarbon. Also disclosed is a process for producing the catalyst composition which includes: (1) contacting a zeolite with an effective amount of an acid under a condition sufficient to effect a reduction in aluminum content of the zeolite to produce an acid-leached zeolite; and (2) impregnating the acid-leached zeolite with an effective amount of a metal compound under a condition sufficient to effect the production of a metal-promoted zeolite.

    摘要: The present invention relates to a process for driving a non-polymerization solution-phase photochemical transformation. A sensitizer, such as a substituted diaminobenzophenone having a solubility in norbornadiene greater than that of Michler's Ketone, may be added to norbornadiene to form a solution, wherein the sensitizer decreases the induction period at the beginning of the reaction, increases the photon or quantum efficiency of conversion of norbornadiene to quadricyclane, and increases the rate of conversion at the end of the reaction. If the solution is irradiated with light from a metal halide-doped mercury arc lamp to photochemically transform the norbornadiene to quadricyclane, the conversion is more efficient than when other light sources are utilized. Furthermore, the addition of triethylamine to the solution tends to result in the formation of fewer by-products in the transformation reaction.

    摘要: A process for preparing distillate fuel compositions from a C2-6 olefinic fraction and a C20+ fraction via molecular averaging is described. The fractions can be obtained, for example, from Fischer-Tropsch reactions, and/or obtained from the distillation or other processing of crude oil. Molecular averaging converts the fractions to a product that includes a significant fraction in the C5-20 range that can be used for preparing a distillate fuel composition. The product is preferably isomerized to increase the octane value and lower the pour, cloud and smoke point. The product can also be hydrotreated and/or blended with suitable additives for use as a distillate fuel composition.

    摘要: Enabling a transalkylation process to handle both C10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column. No longer requiring a rigorous split between C9 and C10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. A further enhancement to the flow scheme is accomplished through the elimination of clay treaters in favor of selective olefin saturation at the exits of a reforming unit and an isomerization unit. These improvements result in an aromatics complex with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.

The process further includes: forming a plurality of elongated optical channels in the substrate, wherein a first optical channel is operative for transmitting light to the plurality of elongated optical channels such that the transmitted light is divided among the plurality of elongated optical channels, thereby forming an optical beamsplitter.
