Abstract:
1. A plasma gasification reactor comprising: a vertically oriented reactor vessel including a bottom section and a top section; the bottom section containing a carbonaceous bed and arranged with one or more plasma torch ports each containing a plasma torch; the top section extending from the bottom section to a roof over and joined with the top section; the top section including an upper portion containing a freeboard region and a lower portion containing a gasification region, the lower portion having an interior surface forming an inverse truncated cone with a narrowest cross-sectional diameter located where the top section is joined to the bottom section, a side wall of the upper portion being oriented at a substantially continuous first angle relative to a vertical axis of the vessel, and a side wall of the lower portion including first and second conical portions being oriented at a substantially continuous second angle relative to the vertical axis of the vessel, wherein the second angle is in a range of between about 5° and about 25° with respect to the vertical axis of the vessel; one or more gas outlet ports from the vessel; one or more feed ports for supply of feed material into the top section, the one or more feed ports being positioned in a cylindrical portion between the first and second conical portions of the side wall of the lower portion of the top section; and one or more tuyeres extending through the top section adjacent to the gasification region for process material including gases and vapors, the tuyeres being located closer to the bottom section of the vessel than the one or more feed ports.
