    摘要: Disclosed herein are methods of making xylene isomers. The methods generally include contacting an aromatics-comprising feed with a non-sulfided catalyst under conditions suitable for converting the feed to a product comprising xylene isomers. The catalyst includes a support impregnated with a hydrogenation component. The support includes a macroporous binder and a sieve selected from the group consisting of a medium pore sieve, a large pore sieve, and mixtures thereof. The selection of the sieve will depend upon the size of the molecules in the feed, intermediate, and product that can be expected from the catalytic reactions. When the molecules are expected to be large, a large pore sieve should be used. In contrast, when the molecules are expected to be smaller, either a large pore sieve, a medium pore sieve, or a mixture thereof may be used. The macropores within the support have been found to be especially beneficial because they help to overcome diffusional limitations observed when utilizing highly-active catalysts lacking such macropores.

    摘要: Disclosed herein is a method of making xylene isomers. More specifically, the method includes contacting a C9 aromatics-comprising feed with a catalyst under conditions suitable for converting the feed to an intermediate product stream comprising xylene isomers, separating at least a portion of the xylene isomers from the intermediate product stream, and recycling to the feed the xylene isomers-lean intermediate product stream. Alternatively, the method of making xylene isomers includes contacting a feed comprising C9 aromatics and less than about 30 wt. % benzene, based on the total weight of the feed, with a non-sulfided, large-pore zeolite impregnated with a Group VIB metal oxide, under conditions suitable for converting the feed to a product stream comprising xylene isomers. The disclosed method is characterized by unexpectedly high ratios of xylene isomers to ethylbenzene, xylene isomers to C9 aromatics (e.g., methylethylbenzene), xylene isomers to C10 aromatics, trimethylbenzene to methylethylbenzene, benzene to ethylbenzene, in the product of the conversion, and the high conversion of C9 aromatics and methylethylbenzene.

    摘要: Processes are disclosed for production of purified products from a fluid mixtures of C8 aromatics by means of integration of perm-selective separations with purified product recovery operations. The perm-selective separations of the invention comprise of one or more devices using polymeric perm-selective membrane devices to separate a meta-xylene enriched stream from fluid mixtures of C8 aromatics thereby producing a fluid comprising the remaining aromatic compounds which advantageously includes para-xylene. Processes of the invention are particularly useful for recovery of very pure meta-xylene and para-xylene co-products from liquid mixtures even containing ethylbenzene as well as the three xylene isomers.

Broadly, the present invention discloses ionic polymer compositions that are useful for perm-selective membrane separations. More particularly, ionic polymers of the invention comprise a plurality of repeating structural units having as a constituent part thereof organic ionic moieties consisting of nitrogen containing anions and/or cations. In the form of non-porous membranes, ionic polymers of the invention facilitate recovery of purified organic and inorganic products from fluid mixtures by means of perm-selective membrane separations. The present invention also provides methods for forming the ionic polymers, for example by treating selected nitrogen-containing organic polymers with acids, or treating a polymeric material comprising a plurality of carboxylate groups with an amine. Ionic polymer compositions of the invention are particularly useful for simultaneous recovery of a permeate product of an increased concentration, and a desired non-permeate stream, from a fluid mixture containing at least two compounds of different boiling point temperatures.

    摘要: Disclosed are methods, systems, apparatuses, and non-transitory computer-readable media for facilitating measurement of organizational culture in real time. In embodiments, an organization culture measurement system may facilitate culture measurement through receipt and comparison of various actions performed by persons associated with the organization. The organization culture measurement system may provide a networking and interaction interface for users within an organization to interact with each other. User actions in the networking and interaction interface may be received by the organization culture measurement system and used to associate one or more cultural classifications and/or signifiers with users. Cultural classifications and/or signifiers associated with users may be used to measure organizational culture on a wider level and incentivize desired cultural traits. Aggregation of classification of users of the networking and interaction interface may allow the organization, as well as external stakeholders, to see high-level measurement of the culture of those using the interface.
