  • Patent number: 10280128
    Abstract: In a process for alkylating an aromatic hydrocarbon feedstock with an olefin feedstock, at least one of the aromatic hydrocarbon and olefin feedstocks is passed through a pretreatment unit containing an adsorbent such that the adsorbent removes impurities contained by the feedstock. Passage of the at least one feedstock through the pretreatment unit is then terminated and a heated inert gas is passed through the pretreatment unit such that the inert gas desorbs impurities from the adsorbent to produce an inert gas effluent stream containing the desorbed impurities. A condensable fluid is added to at least part of the inert gas effluent stream such that at least a portion of the impurities contained therein condense with said fluid to leave a purified inert gas stream, which is recycled to the pretreatment unit.

  • Patent number: 8496735
    Abstract: Apparatus and methods for reducing or eliminating undesirable air-borne substances, such as odors, bacteria, viruses, fungi, and toxins, are provided. A filter containing nanocrystalline metal oxide or metal hydroxide particles may be installed within an air handling apparatus such as an existing HVAC unit located within a building, and particularly within a home, or a portable air processor or purifier. The air handling apparatus comprises a blower which pulls air containing various undesirable substances from within the enclosed environment and directs it through a filtering device containing the nanocrystalline particles. The undesirable substances are sorbed by the nanocrystalline particles thereby creating a deodorized stream of air that may then be directed back into various portions of the enclosed environment or vented to the atmosphere.

  • Patent number: 8480794
    Abstract: A method for adsorbing volatile organic compounds (VOCs) derived from organic matter comprises adsorbing the VOCs onto palladium doped ZSM-5, optionally at ambient temperature. The organic matter can be perishable organic goods such as food, including fruit and/or vegetables, horticultural produce, including plants and/or cut flowers, or refuse. The palladium doped ZSM-5 has a Si:Al ratio of less than or equal to 100:1 and preferably has a palladium content of from 0.1 wt % to 10.0 wt % based on the total weight of the doped ZSM-5.

  • Patent number: 8480770
    Abstract: A hydrogen manufacturing system for performing offgas flow control includes: a vaporizer (1) for heating a material mixture containing a hydrocarbon material; a reforming reactor (2) for generating hydrogen-containing reformed gas by reforming reactions of the material; a PSA separator (5) for repeating a cycle of adsorption and desorption, where in the adsorption PSA separation is performed with an adsorption tower loaded with an adsorbent to adsorb unnecessary components in the reformed gas and extract hydrogen-enriched gas out of the tower, and in the desorption the offgas containing the unnecessary components from the adsorbent and remaining hydrogen is discharged from the tower; and a buffer tank (6) for holding the offgas before supplying to the vaporizer. The offgas flow supply from the tank (6) to the vaporizer is changed continuously over time when the cycle time is changed according to load change on the separator (5).

  • Patent number: 8435329
    Abstract: Gas fired internal combustion engines which are run on contaminated fuel suffer from the buildup of internal deposits and corrosion. This is a particular problem with engines fuelled by biogas, e.g. from waste decomposition. By filtering the fuel via a filter containing an ion-exchange resin substantial improvements can be obtained.

  • Patent number: 8414691
    Abstract: The system and method for recycling and using the heat from compressed gas produced by a biogas treatment plant. The system includes a biogas cleaning stage and a plurality of compression and heat exchanger stages that allows the heat generated by compressed gases to be harvested. After the heat is harvested, it is delivered to a jacketed vessel containing media used to remove contaminants from the biogas. The media inside the jacketed vessel requires regeneration or stripping of harmful VOCs and other contaminants picked up from the biogas. The system also includes an inert gas generator that creates hot inert gas that is delivered to the jacketed vessel that heats the media located therein to remove contaminants. Because the jacket vessel and the media are simultaneously heated, the system's heat-up time is reduced The system also includes a heat exchanger that partially recovers the heat from the inert gas.

  • Patent number: RE44536
    Abstract: A filter includes at least two different adsorptive media. First, chemisorptive media, which is porous and includes an acidic functional group, is used to remove molecular bases, including ammonia, organic amines, imides and aminoalchols, from the atmosphere used in semiconductor fabrication and other processes that require uncontaminated gaseous environments of high quality. Second, physisorptive media is able to adsorb condensable contaminants, particularly those having a boiling point greater than 150 degrees C. The physisorptive media can include untreated, activated carbon.
