An adsorbent system including an enclosure having a cavity defining a humidity-controlled environment and a body having or defining a channel therein. The body is coupled to the enclosure such that a first end of the channel is in selective fluid communication with an ambient environment and a second end of the channel is in fluid communication with the humidity-controlled environment. The system further includes an adsorbent material in the channel, wherein the channel and adsorbent material are configured such that inlet fluid flowing from the first end to the second end through the channel is flowable over at least a portion of the adsorbent material, and such that outlet fluid flowing from the second end to the first end is directly flowable over a majority of the portion of the adsorbent material that is flowable over by the inlet fluid, The system further includes a valve system positioned at or adjacent to or in fluid communication with the first end of the channel. The valve system includes an inlet valve portion that is biased to a closed position to generally block a flow of inlet fluid therethrough and that is movable to an open position when a pressure in the channel is sufficiently low relative to a pressure in the ambient environment. The valve system further includes an outlet valve portion that is biased to a closed position to generally block a flow of outlet fluid therethrough and that is movable to an open position when the pressure in the channel is sufficiently high relative to the pressure in the ambient environment.

Provided herein are methods of making an adsorbent bed useful as a micro-reactor, or a catalytic and/or separation device. The adsorbent bed comprises a metal-organic framework composite. In the present methods, one or more metal-organic frameworks in powder form are mixed in a liquid to produce a metal-organic framework suspension or other type of metal-organic framework coating. A monolith is coated with the suspension or coating to provide the metal-organic framework composite having at least one metal-organic framework coating layer deposited on and bounded to the monolith. The metal-organic framework composite produced has a BET surface area of about 1 m.sup.2/g to about 300 m.sup.2/g and/or a comparative BET surface area of about 40% to about 100% relative to the metal-organic framework monolith, and pore size between about 1 nm and about 50 nm.

The present invention relates to a neutralizing absorbent for decontaminating a leaked chemical substance, a method of preparing the same, and a neutralizer filled with the same. The neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention includes an inorganic adsorbent, which is commonly usable in neutralizing absorption of acidic, basic, and/or organic chemical substances, at 40 to 60 wt %, a thickener at 20 to 30 wt %, a surfactant at 20 to 30 wt %, and a color change indicator, and is formulated in a solid state. The neutralizing absorbent is effective in promptly and safely taking an initial action regardless of the type, nature, and characteristics of acidic, basic, and/or organic chemical substances leaked in the leakage accident of the chemical substance, and accordingly, is useful in preventing secondary accidents. Also, when the neutralizing absorbent is used, there are no concerns about the spread of contamination due to water generated by an acid-base reaction, concerns about the additional occurrence of secondary contamination due to a decontaminating agent can be minimized by using a non-toxic chemical absorbent, and a decontamination process can be visually checked in real time regardless of the type, nature, and characteristics of the leaked chemical substance. Furthermore, when a neutralizer filled with the neutralizing absorbent for decontaminating a leaked chemical substance according to the present invention is used, the leaked chemical substance can be more safely and effectively decontaminated during an initial action.
