There are provided a method capable of producing a large amount of a carbonaceous material for a negative electrode of a non-aqueous electrolyte secondary battery from a carbon precursor impregnated with an alkali metal element or an alkali metal compound, and an apparatus for performing such production.

The method for producing a carbonaceous material for a negative electrode of a non-aqueous electrolyte secondary battery according to the present invention includes a heat treatment step of feeding a carbon precursor containing an elemental alkali metal and/or an alkali metal compound, heating the carbon precursor in a temperature range from 1000° C. to 1500° C. in a non-oxidizing gas atmosphere to produce a carbonaceous material, and discharging the carbonaceous material; and an exhaust gas treatment step of contacting a non-oxidizing exhaust gas containing a gas and a flying carbonaceous matter evolved in the heat treatment step with water or an aqueous solution to treat the exhaust gas.

A device for producing and treating a gas stream is provided that includes an enclosure, of which the lower part is submerged in a liquid supply open at the top and includes at least one liquid intake opening. The submerged lower part of the enclosure contains a volume of this liquid and at least one opening for discharging a gas stream, positioned above the surface of the volume of liquid contained in the enclosure. The device further provides for injecting a gas stream including at least one injection conduit and extends in the upper part inside the enclosure outside the volume of liquid. During operation of the device an incoming gas stream is introduced to create an outgoing gas stream, treated by direct contact with said volume of liquid that is discharged outside the enclosure. A facility inclusive of the device and method of operation are also provided.

The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

A portable air filtration and disinfection device for a respirator system includes a casing, an inhalation filter assembly, and an exhalation filter assembly. The inhalation filter assembly includes an intake duct for receiving breathing air, an inhalation gas filter for filtering the breathing air, and an inhalation duct to provide the filtered breathing air. The exhalation filter assembly includes an exhalation duct for receiving exhaled air, an exhalation gas filter and an exhalation liquid filter for filtering and disinfecting the exhaled air, and an outlet duct for releasing the filtered and disinfected exhaled air.

A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.

A multipurpose pollution reducing-device is shown. The device comprises a tank 1 adapted to be secured with a stand 2 and to store pollution reducing liquid 3 therein. At least one layer of the pebbles 4, constituting a filter layer, is provided inside the tank 1 at the bottom thereof. At least one inlet tube 5 passing through the bottom of the tank 1 is provided for’ allowing entry of the exhaust pollutants into the tank 1. Corresponding perforated inverted tube 6 is provided over the inlet tube 5 such that to discharge exhaust with pollutants near the bottom end of the tank 1. A liquid filling tube 10 is provided at the top end of the tank 1, A liquid level indicator 12 secured to the tank 1 is provided to indicate liquid level present in the tank 1. At least one layer of gauge filer 15 disposed in the tank 1 above the liquid level. An outlet 7 is provided near top end of the tank 1 for facilitating exit of the clean exhaust from the device.
