摘要:
The invention relates to a method for optimising the conductivity provided by the displacement of H+ protons and /or OH- ions in a conductive membrane made of a material permitting the insertion of steam into said membrane, wherein said method comprises the step of inserting under pressure gaseous flow containing the steam into said membrane in order to force said steam into said membrane under a certain partial pressure so as to obtained the desired conductivity at a given temperature, said partial pressure being higher than or equal to 1 bar, a drop in the operational temperature being compensated by an increase in said partial pressure in order to obtain the same desired conductivity. The invention can be used in particularly interesting applications in the fields of high-temperature water electrolysis for producing hydrogen, of the manufacture of fuel cells using hydrogen fuel, and of hydrogen separation and purification.

The invention relates to a plant (100) for the gasification of biomass. It comprises a gasifier (10) and an apparatus (23) for the filtration of the gas. The apparatus comprises a scrubber (31), a tank (41), and a wet electrostatic precipitator (51). The scrubber is in fluid communication with the gasifier and with the tank, and is adapted for the injection of a washing liquid in the gas flow. The tank comprises a bottom area adapted for collecting the liquid and a top area adapted for holding the gas, separated by gravity. The wet electrostatic precipitator is in fluid communication with the top area of the tank, so as to receiving only the gas. The invention further relates to a gasifier comprising a gasification reactor (12), a grate (125) for the support of the biomass in the reactor (12) and a plug (126) for closing the middle part of the grate. The plug is vertically movable so as to close and/or open the middle part of the grate.

The invention relates to composites, comprising at least one hollow fibre, made from an oxygen-transporting ceramic material which is a combination of oxygen anion and electron-conducting ceramic material, or a combination of oxygen anion conducting ceramic material and electron-conducting ceramic or non-ceramic material, whereby the outer surface of the hollow fibre is in contact with the outer surface of the same or a different hollow fibre and the contact points are connected by means of sintering. Further composites contain at least one hollow fibre, made from oxygen transporting ceramic material, which is an oxygen anion and electron-conducting ceramic material, or a combination of oxygen anion conducting ceramic material and electron-conducting ceramic or non-ceramic material, with a connector element for the introduction or removal of fluids on at least one front face, whereby the hollow fibres and the connector element are connected. The composites are of application in obtaining oxygen from oxygen-containing gas mixtures or for carrying out oxidation reactions.
摘要:
An exhaust gas treatment system for an internal combustion engine includes an exhaust pipe (6) and an energy applying device (12). Exhaust gas discharged from the internal combustion engine flows into the exhaust pipe (6). The energy applying device (12) applies energy to the exhaust gas flowing through the exhaust pipe. The energy applied to the exhaust gas is greater than the energy for decomposing nitrogen monoxide (NO) and less than the energy for decomposing nitrogen (N 2 ).
