Abstract: Provided are apparatus and systems for performing a swing adsorption process. This swing adsorption process may involve using a selectivation agent to selectivate the adsorbent material. The selectivation agent may be utilized with the swing adsorption process as an in-situ process. The adsorbent material may be utilized for swing adsorption processes to remove one or more contaminants from a feed stream.

Abstract: Adsorbent materials comprising a core, for example CHA, and at least one coating, for example DDR, are provided herein. Adsorbent contactors and gas separation processes using the adsorbent materials are also provided herein.

Abstract: A process for converting hydrocarbons comprising the step of contacting said hydrocarbons under conversion conditions with a crystalline molecular sieve having a pore size in the range of from about 2 to about 19 ?, said molecular sieve made by a method comprising the steps of (a) providing a mixture comprising at least one source of ions of tetravalent element (Y), at least one trivalent element hydroxide source (OH?), and water, said mixture having a solid-content in the range of from about 15 wt. % to about 50 wt. %. %, preferably of from about 20% to about 30%; and (b) treating said mixture to form the desired crystalline molecular sieve with stirring at crystallization conditions sufficient to obtain a weight hourly throughput from about 0.005 to about 1 hr?1, wherein said crystallization conditions comprise a temperature in the range of from about 200° C. to about 500° C. and a crystallization time less than 100 hr, wherein said crystalline molecular sieve has a zeolite framework type of MFI.

Abstract: The present invention is a coated hydrogenation catalyst that includes a porous support material, an active metal component and a silica precursor, wherein the support material is impregnated with the active metal component and then contacted with the silica precursor. After impregnation, the support material is calcined to form a SiO2 layer. The active metal component can be one or more Group VIII metals, metal oxides, metal sulfides or metal carbides. The support material for the coated catalyst is kieselguhr, alumina, silica or silica-alumina. In a preferred embodiment, the active metal component is platinum, palladium, rhodium, rhenium or iridium and the catalyst includes a zeolite component. The coated catalyst is prepared by first impregnating the support material with the active metal component and then contacting the silica precursor to form an impregnated catalyst. The impregnated catalyst is then calcined to form the coated catalyst having a SiO2 layer.
