摘要:
A device for the capturing and concentrating C0 2 comprising a vessel C comprising one or more tubular ring shaped compartments B comprising a space between an inner and an outer circle containing a solid sorbent capable of capturing C0 2 from a gaseous stream, wherein in an adsorption mode the gaseous stream is introduced in the inner space A of the compartment B and flows through the compartment B, and wherein in a desorption mode a desorption stream is introduced directly into the space between the inner and outer circle of the compartment B and an insert D is used in the inner space A to prevent gasses flowing through the inner circle of compartment B. The invention also relates to a process for the capturing and concentrating C0 2 using the device.

Methods for separating ammonia (NH 3 ) from a gaseous mixture that includes hydrogen (H 2 ), nitrogen (N 2 ), and NH 3 are described. A method includes contacting the gaseous mixture of H 2 , N 2 , and NH 3 with an organoborane containing material to produce a gaseous stream that includes the H 2 and N 2 gas and an organoborane-ammonia complex. The ammonia can then be separated from the complex.

Methods, systems, and materials for capturing carbon dioxide and converting it to a chemical product, e.g., synthetic natural gas, are disclosed. In some embodiments, the methods include the following: providing a dual function material, the dual function material including a carrier portion, adsorbent portions, and methanation catalyst portions; contacting a stream of gas including carbon dioxide with the dual function material until the adsorbent portions are substantially saturated with the carbon dioxide; contacting a stream of hydrogen gas with the dual function material that is substantially saturated with the carbon dioxide; desorbing the carbon dioxide from the dual function material; and reacting the carbon dioxide with the hydrogen gas to form methane; wherein the carbon dioxide is adsorbed and desorbed by the adsorbent portions and the carbon dioxide is reacted with the hydrogen gas to form methane at a substantially similar temperature.
摘要:
This invention is in the field of systems and methods for controlling contamination in high purity environments. This invention relates generally to particulate filtering and treatment of molecular contamination and process gases in enclosures, such as cleanrooms, contamination controlled manufacturing environments, mini-environments, isolators, glove boxes and restricted air barrier systems (RABS). The invention is capable of chemically transforming molecular contamination and process gases into less reactive or inert reaction products while at the same time decreasing the level of biological and nonbiological particulates.

Systems, devices and methods for submarine CO 2 scrubbing are disclosed. The system may comprise an assembly including a sorbent, a scrubbing inlet configured to receive a first airflow during an adsorption mode. The first airflow may comprise air received from a cabin of a submarine. The assembly may be configured to flow the first airflow over and/or through the sorbent during the adsorption mode such that the sorbent removes a portion of CO 2 entrained in the first airflow. The system may also include a scrubbing outlet configured to expel the scrubbed first airflow from the assembly into the cabin. The system may include an outside air inlet configured to receive a second airflow comprising outside air during a regeneration mode. The system may include a regeneration air outlet in configured to expel the second airflow after the second airflow has flowed over and/or through the sorbent during the regeneration mode.
