摘要： A filter device has a support tube, which has an inner face and an outer face and which forms an interior adjoining the inner face, into which interior an inlet opening leads, the support tube having through-openings, which connect the interior to a surrounding space adjoining the outer face of the support tube, and a first filter element, which has an inner face and an outer face. The first filter element is disposed in the interior of the support tube and the outer face of the first filter element is adjacent to the inner face of the support tube. A support body is disposed in the interior of the support tube and the support body adjoins the inner face of the first filter element. The filter device can be disposed in a filter housing and, in particular, can also be used in separating water from hydrocarbons.

摘要： A separation method includes a separation step of using a zeolite membrane composite to separate a branched diolefin from a branched hydrocarbon mixture containing the branched diolefin and at least one branched hydrocarbon in which the number of carbon-carbon double bonds is 1 or less and that is of an equivalent carbon number n to the branched diolefin. The zeolite membrane composite used in this step is a zeolite membrane composite that includes a porous support and a FAU-type zeolite membrane formed on at least one surface of the porous support, and in which the FAU-type zeolite membrane is a silylated FAU-type zeolite membrane including a silyl group at the surface thereof.

摘要： A gas separation method including performing a gas separation operation that separates a source gas into a primary-side gas and a secondary-side gas with a membrane of a membrane module. The source gas contains a combustible component. The gas separation operation includes pressurizing the source gas and supplying the source gas to a primary side of the membrane module and depressurizing a secondary side of the membrane module to a pressure lower than an atmospheric pressure. The primary-side gas has a higher concentration of the combustible component than the secondary-side gas, and the gas separation method further includes detecting a composition of the secondary-side gas and stopping the gas separation operation in an instance in which the composition enters a specified range.

摘要： The invention is an improved method of making an improved carbon molecular sieve (CMS) membrane in which a precursor polymer (e.g., polyimide) is pyrolyzed at a pyrolysis temperature to form a CMS membrane that is cooled to ambient temperature (about 40° C. or 30° C. to about 20° C.). The CMS membrane is then reheated to a reheating temperature of at least 250° C. to 400° C. to form the improved CMS membrane. The CMS have a novel microstructure as determined by Raman spectroscopy. The improved CMS membranes have shown an improved combination of selectivity and permeance as well as stability for separating light hydrocarbon gas molecules such as C1 to C6 hydrocarbon gases (e.g., methane, ethane, propane, ethylene, propylene, butane, butylene).

摘要： One variation of a method includes: ingesting an air sample captured during an air capture period at a target location for collection of a first mixture including carbon dioxide and a first concentration of impurities; conveying the first mixture through a liquefaction unit to generate a second mixture including carbon dioxide and a second concentration of impurities less than the first concentration of impurities; in a methanation reactor, mixing the second mixture with hydrogen to generate a first hydrocarbon mixture comprising a third concentration of impurities comprising nitrogen, carbon dioxide, and hydrogen; conveying the first hydrocarbon mixture through a separation unit configured to remove impurities from the first hydrocarbon mixture to generate a second hydrocarbon a fourth concentration of impurities less than the third concentration of impurities; and depositing the second hydrocarbon mixture in a diamond reactor containing a set of diamond seeds to generate a first set of diamonds.

摘要： An integrated process is provided for producing benzene, toluene, and/or xylene and hydrogen from shale gas under the feeding of carbon dioxide. The integrated process for producing an aromatic compound and hydrogen can efficiently and continuously produce high value-added aromatic compounds and hydrogen without the need to separate methane from shale gas through cryogenic distillation.

摘要： A humidification and selective permeation module in which humidification of a gaseous feed stream and selective permeation of components in the gaseous feed stream using a facilitated-transport membrane occurs within the same unit operation is disclosed. A process for separation of components in a gaseous feed stream using the humidification and permeation module combines continuous humidification of the feed stream and selective permeation using the facilitated-transport membrane.
