Compositions that can be used to adsorb low concentration, of unwanted or target substances from a dynamic fluid stream or from an enclosed static vapor phase. Such adsorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, non-woven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The concentration should be reduced to non-offensive sensed limits or a limit that does not produce a biological response.

Materials and methods for mitigating the effects of halide species contained in process streams are provided. A halide-containing process stream can be contacted with mitigation materials comprising active metal oxides and a non-acidic high surface area carrier combined with a solid, porous substrate. The halide species in the process stream can be reacted with the mitigation material to produce neutralized halide salts and a process stream that is essentially halide-free. The neutralized salts can be attracted and retained on the solid, porous substrate.

In general, this disclosure describes method of capturing and storing CO.sub.2 on a vehicle. The method includes contacting an vehicle exhaust gas with one or more of a first metal organic framework (MOF) composition sufficient to separate CO.sub.2 from the exhaust gas, contacting the separated CO.sub.2 with one or more of a second MOF composition sufficient to store the CO.sub.2 and wherein the one or more first MOF composition comprises one or more SIFSIX-n-M MOF and wherein M is a metal and n is 2 or 3. Embodiments also describe an apparatus or system for capturing and storing CO.sub.2 onboard a vehicle.

The present invention is related to a process for manufacturing a sorbent suitable for a use in a circulating dry scrubber device comprising the steps of: providing quicklime and water in an hydrator; slaking said quicklime via a non-wet route in the hydrator; collecting a lime based sorbent at an exit of the hydrator. The process is characterized in that it comprises a further step of adding at least a first additive comprising: a compound comprising silicon, and/or, a compound comprising aluminum, and/or a compound comprising silicon and aluminum before or during said slaking step, at a molar ratio between silicon or aluminum or a combination thereof and the calcium provided to said hydrator equal to or below 0.2 and equal to or above 0.02. In some other aspects, the present invention is related to a sorbent, a premix, and a flue gas treatment process.

The use of porous crystalline solids constituted of a metal-organic framework (MOF) for the capture of polar volatile organic compounds (VOCs). In particular, the MOF of interest are material having an average pores sizes of 0.4 to 0.6 nm and an hydrophobic core formed by a metal oxide and/or hydroxide network connected by linkers, the linkers being selected from the group including (i) C.sub.6-C.sub.24 aromatic polycarboxylate linkers, such as benzyl or naphtyl di-, tri- or tetracarboxylate, and (ii) C.sub.6-C.sub.16 polycarboxylate aliphatic linkers; the linkers bearing or not apolar fluorinated groups, e.g. —(CF.sub.2)n—CF.sub.3 groups, n being a integer from 0 to 5, preferably 0 ou 3, and/or apolar C.sub.1-C.sub.20 preferably C.sub.1-C.sub.4 alkyl groups, e.g. —CH.sub.3 or —CH.sub.2—CH.sub.3, grafted directly to the linkers and pointing within the pores of the MOF. The MOF solids used in the present invention can be used for the purification of air, for example for the capture of polar VOCs like acetic acid and aldehydes from indoor air in cars, museums and archives, much more efficiently than common adsorbents, particularly in presence of above normal levels of humidity. They can in particular be used for the preservation of cultural heritage.
