An apparatus for capturing a water content from a water containing gas, the apparatus comprising: a housing having an inlet into which the water containing gas can flow; a water adsorbent enclosed within the housing, the water adsorbent comprising at least one water adsorbent metal organic framework composite capable of adsorbing a water content from the water containing gas, the metal organic framework composite comprising: at least 50 wt % water adsorbent metal organic framework; from 0.2 to 10 wt % magnetic particles having a mean particle diameter of less than 200 nm; and at least 0.1 wt % hydrophilic binder comprising a hydrophilic cellulose derivative; and a water desorption arrangement in contact with and/or surrounding the water adsorbent, the water desorption arrangement comprising an alternating current (AC) magnetic field generator located within and/or around the water adsorbent configured to apply an AC magnetic field to the water adsorbent.

A vehicle system having an internal combustion engine and evaporative emission system including a canister is described, wherein canister includes a chamber having a flexible Metal Organic Framework (MOF) material disposed therein. A controllable device is coupled to the flexible MOF material, and a controller is operatively connected to the controllable device and the purge valve. The controller includes an instruction set that is executable to activate the controllable device and control the purge valve to an open state in response to a command to purge the canister, determine an activation parameter for the controllable device, determine a purge flow, integrate the purge flow to determine a total purge mass, and deactivate the controllable device when the total purge mass is greater than a threshold.

The present invention relates to granular functionalized silicas, wherein the Hg pore volume (<4 μm) is more than 0.80 ml/g, d.sub.Q3=10% is more than 400 μm, d.sub.Q3=90% is less than 3000 μm, the ratio of d.sub.50 without ultrasound exposure to d.sub.50 after 3 min of ultrasound exposure is <4.00 and the carbon content is 1.0-15.0% by weight. The inventive granular functionalized silicas can be used as a support material, especially as a support for enzymes.

Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.
