Embodiments of the disclosure can include a circuit breaker, comprising an enclosure comprising: arcing contacts movable axially relative to each other, between an open position of the circuit breaker in which the arcing contacts are separated from each other and a closed position of the circuit breaker in which the arcing contacts are in contact with each other; and a gas inlet configured to blow an arc-control gas to interrupt an electric arc during movement of the arcing contacts from the closed position to the open position, wherein the arc-control gas comprises at least 80% of carbon dioxide; wherein the enclosure further comprises an adsorbing material, which adsorbs carbon monoxide after ionization of the carbon dioxide during arcing, said adsorber being a metal-organic framework comprising nickel and/or iron.

A carbon dioxide reduction system 1 comprises a transport path 4 that transports carbon dioxide and a reduction apparatus 5 that reduces heated carbon dioxide introduced through the transport path 4, wherein the carbon dioxide is heated in the transport path 4 by at least one of recycled energy and exhaust heat.

A filter unit (100) includes a rigid filter block (1) that filters out a gas or particles from a gas mixture flowing through the filter unit (100). The filter block (1) has two end faces (Sf.a, Sf.e) and a shell surface (M). A housing including a pot (4) and a cover (2) surrounds the filter block (1). The pot (4) includes a base (4.1) and a tube (4.2). A gap (Sp) occurs between the tube (4.2) of the pot (4) and the shell surface (M) of the filter block (1). Between one end face (Sf.a) of the filter block (1) and the base (4.1) of the pot (4) there is a flat inner area (3.1) of a deformable damping layer (3). An outer area (3.2) of the damping layer (3) surrounds the inner area (3.1) in a circular ring form and is located in the gap (Sp).

Sorbent material sheets provide for enhanced performance in vapor adsorbing applications over conventional canisters and other emissions control equipment. The sorbent material sheets can be formed as part of a small, lightweight canister, or can be integrated into a fuel tank. The sorbent material sheets can also be used as part of an onboard refueling vapor recovery system to control volatile organic compound emissions from fuel tanks of gasoline vehicles, such as automobiles.
