The invention relates to a method for aluminum nitride coating of cylinder contact surfaces (ZL) of a crankcase (KG) made of an aluminum basic alloy where the aluminum nitride coating is performed by surface nitriding of the aluminum basic alloy, and the activated nitrogen is generated by a high-pressure plasma process.

The invention relates to a process and an apparatus for obtaining a high-hydrogen, low-carbon-monoxide gas which is suitable for feeding low-temperature fuel cells in electric vehicles. A high-hydrogen gas mixture is generated by means of a methanol reforming reaction, using a Cu- and ZrO-containing catalyst material. The carbon monoxide content of the gas is decreased to a concentration of less than approximately 100 ppm by means of a selective methanization using a Ru- and TiO.sub.2 -containing catalyst material and/or by means of a selective oxidation using a Pt- and TiO.sub.2 -containing catalyst material.

The invention relates to a method and to an apparatus for continuously removing metabolically produced carbon dioxide from respired air, such as the air found in life support systems or cabin circulating systems, using two sets of hollow fibers disposed in a flowing, carbon dioxide-selective liquid membrane. The carbon dioxide-containing respired air flows through the first set of hollow fibers and the second set of hollow fibers serves to carry away the permeate stream.

The invention relates to a method for continuously removing nitrogen oxides in exhaust gases of internal combustion engines containing an excess of oxygen by feeding a reactive nitrogen-containing plasma jet into the exhaust gas stream, wherein the plasma jet is generated by electromagnetic high-frequency fields.

A method and an apparatus reduces particles in exhaust gases of an internal combustion engine by passing the exhaust gases through a microwave energy field in a resonator for applying energy and burning the particles. In order to improve the application of energy, the particles are agglomerated beforehand in a high-voltage field of an electrostatic filter.

Method and apparatus for reducing exhaust gases particles

A process for the continuous removal of carbon particles in exhaust gas flows uses a plasma process. A stationary oxidative plasma process achieves a particle burn-up of the excess oxygen in technical combustion processes.
