Abstract
The problems of the prior art are overcome by the apparatus and method disclosed herein. The reactor vessel of a plasma gasifier is operated at high pressure. To compensate for the negative effects of high pressure, various modifications to the plasma gasifier are disclosed. For example, by moving the slag, more material is exposed to the plasma, allowing better and more complete processing thereof. In some embodiments, magnetic fields are used to cause movement of the slag and molten metal within the vessel. An additional embodiment is to add microwave heating of the slag and/or the incoming material. Microwave heating can also be used as an alternative to plasma heating in a high pressure gasification system.
