This disclosure includes regenerated inorganic fermented beverage stabilization and/or clarification media and a process for such regeneration. Inorganic stabilization and clarification media (for processing beer or the like) may include expanded perlite or other expanded natural glasses, diatomaceous earth, silica gel or other precipitated silicas and compositions that incorporate these materials. Such media may be regenerated individually, together in a mixture or together as part of a composite product. The regenerated media meet the requirements for physical and chemical properties for re-use and replacement of the majority of particulate inorganic filtration media and inorganic stabilization media consumed in stabilization and clarification processes, and the related regeneration process provides for substantial benefits to brewers through a reduction of costs to purchase and transport stabilization and clarification media, to dispose of spent cake and/or membrane retentate, while providing for substantial reductions in the introduction of soluble impurities into the fermented beverage.

A process for deodorizing a rosin ester composition is disclosed. The process employs an adsorptive bed containing an adsorbent material. The adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, BET surface area of at least 300 m.sup.2/g, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si—OH] level of 0.5 to 5 unit/nm.sup.2. The deodorized rosin ester composition has an odor intensity reduction of at least 1 unit on odor intensity scale of Offensive Odor Control Act as compared to the rosin ester feedstock. In embodiment, the deodorizing treatment comprises using multi-staged adsorbent system with an adsorbent column having multiple layers of different adsorbent materials.

The present development is a method for capturing and purifying CO.sub.2 from a flue gas stream using a metal aluminate nanowire absorbent and then regenerating the absorbent. After the CO.sub.2 is adsorbed into the absorbent, the adsorbent is regenerated by subjecting the CO.sub.2 saturated adsorbent to a dielectric barrier discharge plasma or to a microwave plasma or to a radio frequency (RF) plasma while ensuring that the external temperature does not exceed 200° C.

Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H.sup.+ZP within a casing for a treatment; and after the treatment, refurbishing the H.sup.+ZP while maintained within the casing via (i) regenerating the non-disinfected H.sup.+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H.sup.+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H.sup.+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H.sup.+ZP while maintained within the casing. Multiple batch sorbent refurbishing implementations are also disclosed.

The present disclosure includes a process for pelletizing a spent bleach earth (SBE) into a clay-biocarbon composite including classifying the SBE based on at least one parameter of the SBE, selecting at least one filler compound and mixing the at least one filler compound with the SBE to make a mixture, forming a plurality of pellets out of the mixture, and pyrolyzing the pellets to produce the clay-biocarbon composite. Pyrolyzing a pelleted spent bleach earth (SBE) may include advancing the pelleted SBE with a distributer to a first thermal chamber for providing even thermal processing, releasing the pelleted SBE to a second auger to cool to room temperature, and condensing at least one volatile compound emitted from the pelleted SBE during thermal processing to produce a condensate for reuse.

The invention provides methods and systems for washing adsorptive media with minimal water consumption. More specifically, the invention provides methods and systems for in situ regeneration and/or sanitization of adsorptive media, such as activated carbon, using back-and-forth washing.

The invention relates to a gas treatment monolith article, said gas treatment article comprising: a full body porous material comprising a porous substrate and an aluminium oxide coating homogeneously distributed throughout said porous substrate, wherein said porous substrate is a fibrous material; and at least one acid gas absorption active component or a precursor thereof impregnated into said porous aluminium oxide coated substrate. The invention further relates to uses of the gas treatment monolith article of the invention.

The present invention relates to methods for the preparation of pellets of sorbent suitable for carbon dioxide capture, to said pellets of sorbent, and to the use of said pellets of sorbent in carbon dioxide capture.

Metal-organic frameworks for capturing one or more of SO.sub.2, CO.sub.2, and H.sub.2O are disclosed herein. Non-limiting examples of metal-organic frameworks include NbOFFIVE-1-Ni and AlFFIVE-1-Ni, among others. The metal-organic frameworks can be used in applications for removing and/or sensing one or more of SO.sub.2, CO.sub.2, and H.sub.2O from a fluid composition or an environment, either of which can proceed under dry or humid conditions and/or at room temperature.

The present disclosure generally relates to a microporous aerogel, processes for preparing a microporous aerogel, and applications for the microporous aerogel. The present disclosure also generally relates to an apparatus for capturing carbon dioxide from a gaseous stream or from the atmosphere, the apparatus comprising a microporous aerogel for selectively adsorbing and desorbing the carbon dioxide.
