摘要： The present disclosure is directed to processes for the selective separation of carbon dioxide (CO2) from multi-component feedstreams containing CO2. The processes use a potassium-form MER framework type zeolite having a stick-like morphology. The potassium is present in the zeolite as K+ in extra-framework locations, and the zeolite is essentially free of an extra-framework cation other than potassium.

摘要： A high selectivity and high CO2 plasticization resistant polymer comprises a plurality of repeating units of formula (I) for gas separation applications. The polymer may be synthesized from a superacid catalyzed poly(hydroalkylation) reaction. Membranes made from the polymer and gas separation processes using the membranes made from the polymer are also described.

摘要： The invention includes a gas processing system for transforming a hydrocarbon-containing inflow gas into outflow gas products, where the system includes a gas delivery subsystem, a plasma reaction chamber, and a microwave subsystem, with the gas delivery subsystem in fluid communication with the plasma reaction chamber, so that the gas delivery subsystem directs the hydrocarbon-containing inflow gas into the plasma reaction chamber, and the microwave subsystem directs microwave energy into the plasma reaction chamber to energize the hydrocarbon-containing inflow gas, thereby forming a plasma in the plasma reaction chamber, which plasma effects the transformation of a hydrocarbon in the hydrocarbon-containing inflow gas into the outflow gas products, which comprise acetylene and hydrogen. The invention also includes methods for the use of this gas processing system.

摘要： A spacesuit contaminant removal system includes at least one membrane separator and a liquid sorbent circuit. The at least one membrane separator is configured to receive a spent air stream from a ventilation system of a spacesuit and absorb a contaminant from the spent air stream into a liquid sorbent. The at least one membrane separator is configured to discharge a clean air stream to the ventilation system and discharge the contaminant in a contaminant stream to a space environment using a vacuum of the space environment. The liquid sorbent circuit is configured to circulate the liquid sorbent through the at least one membrane separator.

摘要： An illustrated view of an exemplary air filter for reducing emissions is presented. The air filter is useful for removing toxic gases from the air surrounding a combustion engine of a vehicle is presented. The air filter is useful for scrubbing the ambient air for removal of toxic contaminants such as carbon dioxide and thus reducing harmful emissions of a vehicle. The air filter though described for a vehicle can also be used in industry settings as well as at home. The air filter is recyclable. Although a vehicle is shown, it is an example only. Other applications are possible and have been contemplated for the air filter 100 including, but not limited to, commercial applications, home applications, industrial applications, etc.

摘要： An apparatus and process for separating a gas mixture is disclosed. The apparatus includes a plurality of membrane separation stages comprising a first membrane stage, a second membrane stage, and a third membrane stage. Each of the first, second, and third membrane stages are designed to separate a gas stream provided to them into a permeate stream and a retentate stream. The retentate stream provided from the third membrane stage is configured to be withdrawn as a product, further processed, or discarded. The apparatus further includes a gas transport device with an inlet in communication with the gas mixture and an outlet in communication with the first membrane stage. The controller is in communication with at least one measuring device, and the controller adapts a behavior of the gas transport device in response to a measurement of the at least one measuring device.
