摘要： A method of real time optimization of a microwave plasma includes adjusting in real time an injection angle of a swirl gas flow of the microwave plasma, the magnitude of the swirl gas flow of the microwave plasma, or the microwave power applied to the microwave plasma. An optimization scheme can be created for a particular process requirement or to address time-varying drift in a system. For example, as the output temperature of the torch drifts as the system reaches steady-state operation, the tuning algorithm can adjust the inputs in order to regain the desired output temperature.

摘要： An apparatus for powder spheroidisation by microwave-induced plasma comprises a microwave generator (4), a microwave cavity (20), a waveguide (6) connecting the microwave generator to the microwave cavity, a plasma tube (3) partially located in the microwave cavity, a powder supply (2) connected to the plasma tube to feed a powder precursor flow thereinto, a gas supply (1) connected to the plasma tube to feed a process gas flow thereinto, in order to form a plasma torch in the plasma tube by coupling the process gas flow with the microwave radiation, and a compressed air supply (9). The microwave cavity comprises at least one opening (25) for the compressed air (91) so that the latter can cool the plasma tube from outside, and the gas supply is connected to the powder supply to let the process gas (11) carry the powder precursor (21) into the plasma tube, and so into the plasma torch in order to make spheroids (31) from the powder precursor by in-flight melting.

Furthermore the microwave driven plasma ion source (1, 201) includes a shielding (4) for shielding off the microwaves from passing from the inside (3) of the microwave driven plasma ion source (1) to the outside of the microwave driven plasma ion source (1), wherein the shielding (4) comprises a shielding outlet (5) for letting out the plasma (101) and the sample ions from the inside (3) of the microwave driven plasma ion source (1) essentially in the plasma torch orientation direction (29) to the outside of the microwave driven plasma ion source (1), the shielding outlet (5) having a shielding aperture. Thereby, the shielding outlet (5) is fluidly coupled to the torch outlet (22) for letting out the plasma (101) and the sample ions from the inside (21) of the plasma torch (20) essentially in the plasma torch orientation direction (29) to the outside of the microwave driven plasma ion source (1), wherein a size of the shielding aperture is less than 150%, preferably less than 125%, particular preferably less than 110% of a size of the torch aperture, wherein both the size of the shielding aperture and the size of the torch aperture are measured in units of area.

摘要： A method of processing carbon dioxide involves creating a carbon dioxide plasma within a liquid medium, such as water. The plasma is fed with carbon dioxide, which generates at least carbon monoxide from the carbon dioxide. The liquid medium can be water, in which case hydrogen may also be generated by the plasma. A consumable carbon electrode (2) may be used. The electrode (2) may supply the carbon dioxide to the plasma via a passageway defined through the electrode (2).
