Abstract: A canister includes an activated carbon molding configured to adsorb an evaporated fuel originating in a fuel tank of a vehicle; and an adsorption chamber accommodating the activated carbon molding. A method of manufacturing the canister includes pressing fibrous activated carbons in a specific direction, or performing suction to thereby gather the fibrous activated carbons in the specific direction and mold the fibrous activated carbons into the activated carbon molding that has a columnar shape; and arranging, inside the adsorption chamber, the activated carbon molding produced such that a pressing direction or a suction direction for the activated carbon molding is perpendicular to a flow direction of the evaporated fuel.

Abstract: A portable oxygen concentrator includes a compressor and a controller. The compressor includes a motor, at least one chamber, and at least one piston operably coupled to the motor and movable within the at least one chamber. In some embodiments, the controller is configured to: determine actual motor speeds for commutations steps of the motor during a first rotational cycle; determine an average motor speed during the first rotational cycle; determine a voltage pattern based at least on a comparison of the average motor speed during the first rotational cycle and the actual motor speeds for the commutation steps of the motor during the first rotational cycle; and cause the voltage pattern to be applied to the motor during a second rotational cycle to reduce differences between applied motor torque and variable torque load imparted by the at least one piston.

Abstract: A device for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having an opening and a sorbent regeneration system. The device also includes a capture structure coupled to the release chamber, having at least one collapsible support and a plurality of tiles spaced along the collapsible support. Each tile has a sorbent material. The capture structure is movable between a collection configuration and a release configuration. The collection configuration includes the capture structure extending upward from the release chamber to expose the capture structure to an airflow and allow the sorbent material to capture atmospheric carbon dioxide. The release configuration includes the collapsible support being collapsed and the plurality of tiles being sufficiently enclosed inside the release chamber that the sorbent regeneration system may operate on the plurality of tiles to release captured carbon dioxide from the sorbent material and form an enriched gas.

Abstract: Some embodiments are directed to a system for extracting carbon dioxide from a fluid. The system can include a fluid source and a reactor. The reactor can include one or more chambers, and each chamber can include one or more monoliths for adsorbing carbon dioxide from the fluid. The chambers can be alternatively unsealed for a contacting mode and sealed for a regeneration mode. A power source can provide an electric current to the monoliths to release carbon dioxide adsorbed by the monoliths. Each chamber can include an array of monoliths. Each monolith can include a sorbent that adsorbs carbon dioxide from fluid. The system can include modular components such that the number of reactors can be increased or decreased.

Abstract: Processes, compositions, and apparatus are disclosed. A first process includes providing a cyclopropenimine (CPI). A second process includes providing 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The first and second processes include reacting the CPI and DBU, respectively, with carbon dioxide (CO2) in the presence of a nucleophilic species (NuH) and releasing CO2 from products of the reactions by heating to a temperature below about 120° C. A process of direct air capture includes obtaining atmospheric CO2, reacting the CO2 with an organic base having an imine moiety to form a NuCO2− salt, and heating the NuCO2− salt to a temperature below about 120° C. A composition for low-temperature CO2 release includes a tris(amino)cyclopropenium (TAC+) ion and NuCO2−. An apparatus includes a component configured to provide a composition, including a CPI, for capturing CO2 and a component configured to release the CO2 by heating a to a temperature below 120° C.

Abstract: One aspect of the present disclosure provides a canister configured to adsorb and desorb fuel vapor generated in a fuel tank of a vehicle. The canister includes a charge port, a purge port, an atmosphere port, a first adsorption chamber and a second adsorption chamber directly coupled to the charge port and the purge port or indirectly coupled to the charge port and the purge port via an additional chamber, a first adsorption member housed in the first adsorption chamber, and a second adsorption member housed in the second adsorption chamber. The first adsorption member includes: an adsorption sheet formed of a fiber having properties to adsorb the fuel vapor; and granules having properties to adsorb the fuel vapor and arranged to be dispersed on a surface of or an inside of the adsorption sheet. The adsorption sheet is wound around or folded to form two or more layers.

Abstract: A sorption structure used in a plasma process chamber includes an inner layer having one or more heating elements to heat the sorption structure, a middle section having a lattice structure and a coolant flow delivery network through which a coolant circulates to cool the sorption structure, and a vacuum flow network that is connected to a vacuum line to create low pressure vacuum. The lattice structure includes network of openings defined in a plurality of layers. The inner layer is disposed adjacent to the middle section and an outer layer of the lattice structure faces an interior region of the chamber. The openings in the layers of the lattice structure progressively increase in size from the inner layer to the outer layer. The lattice structure is used to adsorb by-products released in the process chamber and the vacuum flow network is used to remove the by-products.

Abstract: An enhanced capture structure is disclosed, including a sorbent structure having a CO2 sorbent material. The capture structure also includes a plurality of barriers extending outward from the sorbent structure, each sized and positioned such that as an airflow passes along the sorbent structure, a high pressure region forms proximate the sorbent structure on a first side of the barrier facing into the airflow and a low pressure region forms proximate the sorbent structure on a second side of the barrier facing away from the airflow. The barriers on one side of the sorbent structure are staggered with respect to barriers on the other side such that a plurality of high and low pressure regions are formed, each high pressure region being formed opposite a low pressure region on the other side of the structure, creating a pressure differential that promotes CO2 mass transfer into the sorbent material via convection.

Abstract: An oxygen production system (100) may include a main control module (120) and a molecular sieve module (140). The molecular sieve module (140) may include a molecular sieve and a molecular sieve information unit. The molecular sieve information unit may be configured to store information of the molecular sieve. The main control module (120) may be configured to read, write and/or update the information of the molecular sieve stored in the molecular sieve information unit. When reading, in response to at least part of the information of the molecular sieve exceeding a preset range, the main control module (120) may control the oxygen production system (100) to perform a corresponding operation. The oxygen production system (100) may occupy small space, have good performance and a high oxygen production efficiency, and enable a user to obtain a more user-friendly experience.
