摘要： A monolithic catalyst used for a carbon dioxide hydrogenation reaction and a method for preparing the same. The catalyst comprises a carrier, a coating, and active components. The carrier is a honeycomb ceramic. The coating and the active components are separately applied to honeycomb ceramic hole walls from inside to outside. Moreover, each of the honeycomb ceramic holes is divided into an upper segment and a lower segment, and different active components are separately loaded on the two segments. The method for preparing the monolithic catalyst comprises first applying a coating to a honeycomb ceramic by means of impregnation to obtain a coating-containing carrier, and then applying active components to an upper segment and a lower segment of the coating-containing carrier successively by means of impregnation to obtain the monolithic catalyst.

摘要： An aftertreatment component for use in an exhaust aftertreatment system. The aftertreatment component comprises an aftertreatment substrate and a compressible material. The compressible material may be formed from a plastic thermoset, a rubberized material, or a metal foil which permits for the selective expansion of the substrate within the compressible material, while also reducing cost and manufacturing complexity. In various embodiments, the aftertreatment substrate and the compressible materials may be formed separately and coupled to each other, or they may be formed concurrently via coextrusion.

摘要： According to one embodiment, a catalyst system that reduces polymeric fouling may include at least one chromium compound, at least one aluminum compound, and at least one antifouling agent or a derivative thereof. The antifouling agent may have a structure including a central aluminum molecule bound to an R1 group, bound to an R2 group, and bound to an R3 group. One or more of the chemical groups R1, R2, and R3 may be antifouling groups having the structure —O((CH2)nO)mR4, a phosphonium or phosphonium salt, a sulfonate or sulfonate salt, a sulfonium or sulfonium salt, an ester, an anhydride, a polyether, or a long-chained amine-capped compound, where n is an integer from 1 to 20, m is an integer from 1 to 100, and R4 is a hydrocarbyl group. The chemical groups R1, R2, or R3 that do not include an antifouling group, if any, may be hydrocarbyl groups.

摘要： Provided is a method for directly preparing dimethyl ether by synthesis gas, the method comprises: the synthesis gas is passed through a reaction zone carrying a catalyst, and reacted under the reaction conditions sufficient to convert at least a portion of the raw materials to obtain the reaction effluent comprising dimethyl ether; and the dimethyl ether is separated from the reaction effluent, wherein the catalyst is zinc aluminum spinel oxide. In the present invention, only one zinc aluminum spinel oxide catalyst is used, which can make the synthesis gas to highly selectively form dimethyl ether, the catalyst has good stability and can be regenerated. The method of the present invention realizes the production of dimethyl ether in one step by the synthesis gas, and reduces the large energy consumption problem caused by step-by-step production.

摘要： An oxygen transfer agent comprising a metal-boron oxide is provided. The average oxidation state of the metal in the metal-boron oxide is about 3+, and has 10% or less of a stoichiometric excess in moles of Mn with respect to the boron. The oxygen transfer agent may further comprise a magnesia-phosphate cement. The oxygen transfer agent is capable of oxidatively dehydrogenating a hydrocarbon feed at reaction conditions to produce a dehydrogenated hydrocarbon product and water. The oxidative dehydrogenation can take place under reaction conditions of less than 1000 ppm weight molecular oxygen, or in the presence of more than 1000 ppm weight of molecular oxygen. Also provided are methods of using the oxygen transfer agents, and an apparatus for effecting the oxidative dehydrogenation of the hydrocarbon feed.

摘要： A catalyst for synthesizing a carbon nanotube includes a support containing a metal, and an active metal impregnated on the support. The active metal includes cobalt and manganese. A surface molar ratio of the active metal relative to the metal of the support is 40% or less of a bulk molar ratio of the active metal relative to the metal of the support. A carbon nanotube having high purity and low resistance is obtained from the catalyst.
