    摘要： An oxygenate to olefins (OTO) process, comprising the steps of: (i) purifying an oxygenate feedstream comprising one or more ionic contaminants by contacting the feedstream with a membrane, resulting in the formation of a retentate and a permeate separated by the membrane, which permeate is a purified oxygenate stream which contains a lower ionic contaminant concentration than the original oxygenate feedstream; (ii) introducing the purified oxygenate stream into an oxygenate to olefins reaction zone; and (iii) contacting the purified oxygenate stream with a molecular sieve catalyst in the oxygenate to olefins reaction zone to form a product stream comprising olefins.

    摘要： Catalytic structures include a catalytic material disposed within a zeolite material. The catalytic material may be capable of catalyzing a formation of methanol from carbon monoxide and/or carbon dioxide, and the zeolite material may be capable of catalyzing a formation of hydrocarbon molecules from methanol. The catalytic material may include copper and zinc oxide. The zeolite material may include a first plurality of pores substantially defined by a crystal structure of the zeolite material and a second plurality of pores dispersed throughout the zeolite material. Systems for synthesizing hydrocarbon molecules also include catalytic structures. Methods for synthesizing hydrocarbon molecules include contacting hydrogen and at least one of carbon monoxide and carbon dioxide with such catalytic structures. Catalytic structures are fabricated by forming a zeolite material at least partially around a template structure, removing the template structure, and introducing a catalytic material into the zeolite material.

    摘要： The dual-zeolite catalyst for production of ethylbenzene is formed by mixing at least two different zeolites selected from mordenite, beta, ZSM-5, ZSM-11, ZSM-12, ZSM-22, ZSM-23, MFI topology zeolite, NES topology zeolite, EU-1, SAPO-5, SAPO-34, SAPO-11 and MAPO-36 zeolites and an inactive alumina binder. The two zeolites have different topology and possess dissimilar and unique physical and chemical characteristics, including particle size, surface area, pore size and acidity. The preferred amount of the two zeolites may range from 10 to 90 wt % of the total catalyst amount in the final dried and calcined form, preferably the zeolites are in equal parts by weight.

    摘要： Process for the separation of close boiling isomeric compounds comprising distilling a dilute solution of isomers in a high boiling compound in the presence of a solid adsorbent. Multi and/or monobranched as well as cyclic isomers are withdrawn at the top of the distillation column, while straight chain and/or mono branched isomers are retained within the solid adsorbent. The diluent solution of the high boiling compound is withdrawn from the bottom of the distillation column and recycled, where it may be combined with the feed isomer mixture or recycled straight to the top of the adsorption column.

    摘要： A precursor to a catalytic structure comprising zinc oxide and copper oxide. The zinc oxide has a sheet-like morphology or a spherical morphology and the copper oxide comprises particles of copper oxide. The copper oxide is reduced to copper, producing the catalytic structure. The catalytic structure is fabricated by a hydrothermal process. A reaction mixture comprising a zinc salt, a copper salt, a hydroxyl ion source, and a structure-directing agent is formed. The reaction mixture is heated under confined volume conditions to produce the precursor. The copper oxide in the precursor is reduced to copper. A method of hydrogenating a carbon oxide using the catalytic structure is also disclosed, as is a system that includes the catalytic structure.
