Adsorbent structures for removal of water and fuel contaminants in engine oil

Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

Devices and methods for removal of condensed, blow-by contaminants with small molecular dimensions from the circulating lubricating engine oil of internal combustion engines, including automotive engines, with a positive crankcase ventilation system are disclosed. These condensable blow-by contaminants include water, alcohols and hydrocarbons with preponderantly seven or fewer carbon atoms. A macroporous structure comprising alumino-silicate particles with micro-pores is at least partially immersed in the circulating oil. The micro-pores are sized to adsorb the small, condensed, blow-by, contaminant molecules but not the larger oil molecules. The particles may be multi-layered, with an inner layer adapted for adsorption of polar molecules. Adsorption is most extensive at lower oil temperatures and decreases as the oil temperature increases. Thus at low temperatures the contaminant molecules may be adsorbed, removed from the oil and temporarily stored in the micropores. At high temperatures some of the contaminants will desorb and be re-incorporated in the oil. The desorbed contaminants will be carried with the higher temperature oil into the engine crankcase where they may vaporize and be removed by the engine positive crankcase ventilation system.

Attrition resistant hardened zeolite materials for air filtration media

Номер: US20120118160A1
Принадлежит: JM Huber Corp

Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.

Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas.

Catalytic adsorbents obtained from municipal sludges, industrial sludges, compost and tobacco waste and process for their production

Номер: US20130102456A1
Автор: Teresa J. Bandosz

Industrial waste derived adsorbents were obtained by pyrolysis of sewage sludge, metal sludge, waste oil sludge and tobacco waste in some combination. The materials were used as media to remove hydrogen sulfide at room temperature in the presence of moisture. The initial and exhausted adsorbents after the breakthrough tests were characterized using sorption of nitrogen, thermal analysis, XRD, ICP, and surface pH measurements. Mixing tobacco and sludges result in a strong synergy enhancing the catalytic properties of adsorbents. During pyrolysis new mineral phases are formed as a result of solid state reaction between the components of the sludges. High temperature of pyrolysis is beneficial for the adsorbents due to the enhanced activation of carbonaceous phase and chemical stabilization of inorganic phase. Samples obtained at low temperature are sensitive to water, which deactivates their catalytic centers.
