A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

A plasma reactor comprises a housing, a first fluid inlet, a second fluid inlet, a first electric field generator, and an effluent outlet. The housing includes an axial aligned passageway and an internal reactor chamber coupled with the passageway. The first fluid inlet receives and delivers a first fluid to the reactor chamber. The second fluid inlet receives and delivers a second fluid to the reactor chamber. The first electric field generator is positioned in the reactor chamber and includes a first electrode and a spaced apart second electrode. The first electric field generator generates a first electric field, wherein the first fluid passes through the first electric field creating a plasma which is injected into the second fluid while the second fluid is flowing through the passageway to create an effluent. The effluent outlet receives the effluent from the reactor chamber and delivers it to a destination.

An apparatus for producing synthesis gas at high capacity is described, wherein particularly fast conversion and operation for a long time without interruption is obtained. The apparatus comprises a reactor (1) having a reactor chamber (2) which comprises at least one first inlet (5) connected to a source of hydrocarbon fluid and at least one outlet (15); further a plasma burner (7) having a burner part (11) which is adapted to produce a plasma; and at least one second inlet (6) connected to a source of CO.sub.2 or H.sub.2O. The reactor chamber (2) defines a flow path from the first inlet (5) to the outlet (15), wherein the burner part is located, with respect to the flow path, between the first inlet (5) for hydrocarbon fluid and the second inlet (6) for CO.sub.2 or H.sub.2O; and wherein the second inlet (6) is located with respect to the flow path such that the second inlet (6) is at a location where between 90% and 95% of the hydrocarbon fluid is thermally decomposed. Further a method for operating an apparatus for producing synthesis gas is described.

A plasma reactor for enriching water with nitrogen compounds. The plasma reactor includes a water container (8); a plasma head (3) connected with a microwave generator (1) by a waveguide (2); a quartz tube (5) having a first end situated within the plasma head (3) and a second end that protrudes into the water container (8); a gas circulator (9) configured to introduce gas into the first end of the quartz tube (5) so that the introduced gas comes out through the second end of the quartz tube (5); a discharge generating rod (4) configured to he inserted into the plasma head (3) within the quartz tube (5) to generate a discharge in the quartz tube (5) and to be moved out of the head (3) after the discharge has been generated.

An arc reactor and a process for the production of nanoparticles are disclosed. The reactor has a crucible in a gas-tight housing having a carrier gas inlet and a spaced-apart carrier gas outlet. The carrier gas inlet is directed to the side of the crucible opposite the crucible opening. The inlet can be disposed below the crucible and directed to the side of the crucible opposite the crucible opening. The carrier gas outlet is disposed above the crucible and exits the housing above the crucible. The carrier gas outlet is formed by a hood disposed at a distance above the crucible, which is separated from the crucible and formed by an exhaust pipe that connects the hood to the carrier gas outlet of the housing. The reactor housing has at least one inlet for cooling gas. This can be directed at an interstice formed between the crucible and the hood.

Devices are provided for generating a plasma field for dissociating water into elemental hydrogen and water. The elemental hydrogen may be used directly to produce power, or may be stored for use as an energy source or as a commodity. The devices of the present invention can provide on site, point of use sources for producing elemental hydrogen. In addition, the devices can produce a net positive energy output.
