A reaction vessel has a reaction chamber, and two or more plasma nozzles coupled to the reactor chamber. Each plasma nozzle has a microwave plasma generator powered by a magnetron, and a feed tube for directing a flow of material via the plasma generator to a respective inlet to the reaction chamber whereby the plasma generator at least partly ionises the material to form a plasma prior to entry of the at least partly ionised material into the reaction chamber. The plasma-generating region of each nozzle is separated from the reactor chamber at a distance between 0.005 to 1 m. |
