Embodiments discloses herein relate to methods of processing coal. A method to process coal includes subjecting raw coal to a liquefaction process effective to form a liquid pitch resin and subjecting the liquid pitch resin to a filtration process. The method further includes subjecting the liquid pitch resin to a low crystallinity spinning process to form a raw fiber. The raw fiber is then further subjected to a stabilization process configured to oxygen cross-link the fiber to form a stabilized fiber and then subjecting the stabilized fiber to a carbonization process to form a low thermal conductivity carbon fiber.

The present invention includes apparatuses and methods to separate a gas from a gaseous mixture using supercapacitive swing adsorption.

Disclosed is a gas supply device provided for a container in which a breathing plant is housed. The device supplies nitrogen-enriched air into the container. The device is provided with a malfunction diagnosis section which checks whether each of components of the device works properly or not and specifies a malfunctioning portion if an oxygen concentration of the nitrogen-enriched air does not fall to or below a predetermined concentration. The malfunction diagnosis section checks whether each of an air pump, a motor, and a switching mechanism works properly or not, and determines that an adsorbent is not working properly when it is determined that all of the air pump, the motor, and the switching mechanism are working properly.

An object of the present invention is to provide a water collecting device and a water collecting method each of which makes it possible to efficiently extract water absorbed as moisture in a polymeric moisture-absorbing material. The object is achieved by a water collecting device including: a stimulus applying section for applying an external stimulus which is intended to decrease the affinity with water of a polymeric moisture-absorbing material; and a vibration section for providing vibration to the polymeric moisture-absorbing material having a decreased affinity with water and thereby causing water to be released from the polymeric moisture-absorbing material.

A chemical substance concentrator includes a tubular body, and a plurality of adsorption parts provided with predetermined intervals on a surface of the tubular body facing an inside of the tubular body. The chemical substance concentrator can cause a sample to easily pass through the chemical substance concentrator.

A controller may control a system for extracting liquid water from air comprising a thermal unit, a primary desiccant wheel, and a regeneration fluid path. The controller may comprise a plurality of sensors, a plurality of motors, and a microcontroller coupled to the plurality of sensors and the plurality of motors. The microcontroller may be configured to determine a water extraction efficiency based on at least one signal received from at least one of the plurality of sensors and maximize the water extraction efficiency by adjusting a speed of at least one of the plurality of motors in response to the determined water extraction efficiency. The water extraction efficiency may be a value obtained by multiplying a regeneration fluid flow rate within the regeneration fluid path by an absolute humidity of air on a side of the primary desiccant wheel opposite a side in communication with the thermal unit.

A sorbent product, including from about 1 wt % to about 99 wt %, based on the total weight of the sorbent product, of at least one base sorbent material; and from about 1 wt % to about 99 wt %, based on the total weight of the sorbent product, of at least one binder. The sorbent product may further include at least from about 0 wt % to about 99% wt %, based on the total weight of the sorbent product, of at least one additional additive. Methods for making same and methods and systems for controlling multiple pollutants are also included.

A system and a method for segregating one or more component gases from atmospheric air are disclosed. The system comprises one or more segregation units, one or more sensors, one or more hardware processors, and a memory unit. Each segregation unit of the one or more segregation units comprises at least one of: an enclosure, one or more adsorptive composites, one or more airflow-controlling units, and a gas-sealed flap. The one or more adsorptive composites is operatively positioned in the enclosure to adsorb the one or more component gases from the atmospheric air during the processing of the atmospheric air as the atmospheric air interacts with the one or more adsorptive composites. The system employs one or more artificial intelligence models and one or more predictive artificial intelligence models to optimize the one or more operational parameters of the one or more segregation units.
