Abstract
A gas filter comprises a housing (30) having a gas inlet (55), a gas outlet (65) and at least one chamber (70) therebetween containing carbon nanotubes (110). The chamber (70) has a port (90) and is configured for simultaneous gas ingress to and gas egress from the carbon nanotubes (110) through the port (90).
Claims72
A gas filter comprising:
- a housing having a gas inlet comprising a first port, a gas outlet comprising a second port and at least one chamber therebetween containing carbon nanotubes,
- the chamber having a third port for simultaneous gas ingress to and gas egress from the carbon nanotubes through said third port.
A gas filtration device comprising:
- a gas filter having a housing with a gas inlet comprising a first port, a gas outlet comprising a second port, and at least one chamber therebetween containing carbon nanotubes, the chamber having a third port for simultaneous gas ingress to and gas egress from the carbon nanotubes through said third port;
- an entry flow section to supply gas to the gas inlet of the gas filter;
- and
- a gas exhaust section to exhaust gas from the gas outlet of the gas filter.
1 more element
A gas filtration system comprising:
- a gas filter having a housing with a gas inlet comprising a first port, a gas outlet comprising a second port, and at least one chamber therebetween containing carbon nanotubes, the chamber having a third port for simultaneous gas ingress to and gas egress from the carbon nanotubes through said third port;
