A system and method for cleaning, conditioning, and/or rejuvenating carbon-based sorbents is disclosed where a chemical cleaning process is used to separate contaminants from the sorbent. The contaminants can be disposed of or recycled for industrial uses. The cleaned and/or rejuvenated carbon-based sorbent is recycled back into a reverse venturi shaped fluidized bed apparatus for later use. Spent carbon-based sorbent can be routed for appropriate disposal. The carbon-based sorbents include, but are not limited to, activated carbon sorbent and biochar sorbent. Optionally, the sorbents can be processed through the system prior to exposure to contaminated emissions to enhance and increase the porosity of the outer surface of the sorbents.

Method and apparatus for separating a target substance from a fluid or mixture. Capsules having a coating and stripping solvents encapsulated in the capsules are provided. The coating is permeable to the target substance. The capsules having a coating and stripping solvents encapsulated in the capsules are exposed to the fluid or mixture. The target substance migrates through the coating and is taken up by the stripping solvents. The target substance is separated from the fluid or mixture by driving off the target substance from the capsules.

Provided are a sheet for pets which contains carbon and has a superior appearance, and a method of manufacturing the sheet for pets. A sheet for pets is provided with a liquid-permeable front surface sheet, a liquid-impermeable back surface sheet, an absorbent layer that contains carbon and is positioned between the front surface sheet and the back surface sheet, and a front surface-side liquid-permeable sheet that is black and is positioned on the front surface sheet-side of the absorbent layer. The front surface-side liquid-permeable sheet is preferably formed from pulp fibers that have been dyed black.

A process to prepare a carbon molecular sieve adsorbent composition comprises steps beginning with an activated carbon having specific effective micropore size. The activated carbon is impregnated with monomers or partially polymerized polymer, allowed to complete polymerization, and then carbonized such that the impregnant shrinks the micropores to another specific effective micropore size. Finally, the impregnated/polymerized/carbonized product is annealed at a temperature ranging from 1000? C. to 1500? C., which ultimately and predictably shrinks the micropores to a size ranging from 4.0 Angstroms to 4.3 Angstroms. The invention surprisingly enables fine tuning of the effective micropore size, as well as desirable selectivity, capacity and adsorption rates, to obtain highly desirable carbon molecular sieving capability particularly suited for use in, for example, fixed beds in pressure swing or temperature swing processes to enable propylene/propane separations.

An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.

A method of adsorbing a dye from an aqueous solution including contacting a composition with the aqueous solution. At least a portion of the dye adsorbs to the composition. The composition includes biochar, cellulose nanocrystals, and a layered double hydroxide (LDH). The LDH includes Cu and Fe. Particles of the LDH and the biochar at least partially cover an outer surface of the cellulose nanocrystals.

Continuous fuel flow enhancer device for internal combustion engines has two internal solid phases in the fuel circulation where the following components intervene: silica gel (SiO2 nH2O) which performs a dehydration process, and in a second phase, activated carbon for organic compounds intervene, which performs an adsorption, purification and dehydration process.

The electronic structure of nanowires, nanotubes and thin films deposited on a substrate is varied by doping with electrons or holes. The electronic structure can then be tuned by varying the support material or by applying a gate voltage. The electronic structure can be controlled to absorb a gas, store a gas, or release a gas, such as hydrogen, oxygen, ammonia, carbon dioxide, and the like.

An adsorption device for compressed gas, is provided with a vessel with an inlet for the supply of a compressed gas to be treated, and an outlet for treated gas and an adsorption element is affixed in the vessel. The adsorption element extends along the flow direction of the compressed gas to be treated, between the inlet and the outlet. The adsorption element has a monolithic supporting structure that is at least partially provided with a coating that contains an adsorbent.

In order to provide a separating agent for liquid chromatography that is able to separate a protein using target characteristics as an index while retaining the original steric structure, the separating agent for liquid chromatography is equipped with a substrate, a recognition site including a compound that operates by recognizing characteristics of biopolymers such as proteins, and a spacer that bonds the recognition site to the substrate, wherein the spacer has an effective length to enable the recognition site to operate by reaching deep portions of the steric structure of a target biopolymer.
