Adsorption heat exchanger devices (11, 25) are provided for use in solid sorption refrigeration systems (1) together with methods for making such devices and adsorbent structures therefor. The methods include applying a curable binder, in solution in a solvent, to granular adsorbent material, and then evaporating the solvent and curing the binder. The curable binder solution is sufficiently dilute that, during evaporation of the solvent, the binder becomes concentrated around contact points between granules (18) of the adsorbent material whereby localized bonds (19) are formed around the contact points on curing of the binder.

A method including adding to or positioning in a vehicle air conditioning system a solid form adsorbent. The solid form adsorbent includes a plurality of discrete adsorbent particles spatially bound in place by point bonding with a binder. At least about 25% of the external surface area of a majority of the particles is not sealed off by the binder and is available for adsorption.

A method for producing biochar aggregate particles that comprising the steps of (i) collecting or producing treated biochar fines less than 1 mm, (ii) adding a binding agent to the fines, (iii) forming the fines and binding agent into solid aggregate particles. The steps may further include, for example, adding additives to the fines, drying the solid aggregate particles, activing the binder after forming the solid aggregate particles with heat or cold temperatures and/or treating the biochar fines prior to forming the aggregate particles.

A process for producing an adsorbent comprising activated carbon, wherein the process comprises a molding step of molding an adsorbent through a plurality of stages, and wherein the molding step comprises molding in a final stage performed by tableting.

The present disclosure provides for a porous gas sorbent monolith with superior gravimetric working capacity and volumetric capacity, a gas storage system including a porous gas sorbent monolith of the present disclosure, methods of making the same, and method for storing a gas. The porous gas sorbent monolith includes a gas adsorbing material and a non-aqueous binder.

Described herein is a building panel comprising a substrate and an odor and VOC reducing coating applied to the substrate, the coating comprising a blend of a first component comprising ethylene urea; a second component comprising silica; and a rheology modifier.

A preparation method for a combined modified straw active particulate carbon adsorption material and use of same. The preparation method for the combined modified straw active particulate carbon adsorption material comprises the following steps: 1) mixing straw powders, distilled water, a binder and a composite mineral, then pelletizing same, and then placing same in a tube furnace for pyrolysis to prepare straw particulate carbon; 2) introducing an inert gas into a modification reagent, adjusting the pH value combined and 3) soaking the straw particulate carbon into the combined modification solution for 30 min, and performing cleaning and drying, so as to obtain a combined modified straw active particulate carbon adsorption material. The combined modified straw active particulate carbon has a good adsorption effect on phosphate group in low-pollution water.

A composite material for purifying air includes a porous foam material which is an open-cell polyurethane foam net; and a mixture sprayed on the interior and/or the surface of the porous foam material, the mixture including an absorbent material, a treating agent and an adhesive; wherein the adsorptive material is diatomite, and the treating agent is alkali solution.

Described herein is a building panel comprising a substrate and an odor and VOC reducing coating applied to the substrate, the coating comprising a blend of a first component comprising ethylene urea; a second component comprising silica; and a rheology modifier.

A method for preparing a nano-enabled activated carbon block, a nano-enabled activated carbon block produced by the method, a household water filtration system comprising the nano-enabled activated carbon block, and a method for filtering tap water using the household water filtration system are provided. The method includes contacting a solution including a metal(lic) precursor (e.g. a titanium compound and/or an iron compound and/or a zirconium compound) with activated carbon particles such that the solution fills pores of the activated carbon particles. The method further includes causing a metal (hydr)oxide (e.g. titanium dioxide and/or zirconium dioxide and/or iron oxide) to precipitate from the solution thereby causing metal oxide nanoparticles to become deposited within pores of the activated carbon particles. The method also includes preparing a nano-enabled activated carbon block from the activated carbon particles having metal oxide nanoparticles deposited within the pores thereof.
