Abstract

A method and system is disclosed for converting a feed, such as a carbonaceous waste, to dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents. The feed is injected into a molten bath which, at a sufficient temperature, causes conversion of essentially all of the feed to its atomic constituents, such as atomic carbon. Essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath. An oxidant is injected into the molten bath at a rate sufficient to cause the oxidant to exothermically react with the dissolved atomic constituents to heat at least a portion of the molten bath. The heated portion is thereafter exposed to subsequently injected feed, whereby essentially all of the subsequently injected feed is converted to atomic constituents, and whereby essentially all of the atomic constituents which are to be oxidized in the molten bath dissolve in the molten bath, thereby converting the feed to the dissolved atomic constituents for subsequent oxidation of the dissolved atomic constituents.

Claims

1. A method of converting an oxidizable feed containing carbon values, comprising the steps of:

a) injecting all the feed by submerged injection into a molten bath to convert essentially all of its oxidizable component into atomic constituents and dissolving said constituents in the bath;

b) injecting separately at a seperate location or at a different time an oxidant into the molten bath in an amount which is sufficient to cause the oxidant to oxidize dissolved carbon atomic constituents and heat a portion of the molten bath; and

c) injecting additional feed containing carbon values by submerged injection into the molten bath to convert essentially all of its oxidizable component into atomic constituents and dissolving said constituents in the bath.

2. A method of claim 1, wherein the feed and the oxidant are alternately injected into the molten bath.

3. A method of claim 2, wherein the feed and the oxidant are injected into the molten bath at the same location within the molten bath.

4. The method of claim 1, wherein the feed and the oxidant are injected into the molten bath at different locations.

5. A method of claim 4, wherein the oxidant is injected into the molten bath in a direction which is at about a ninety degree angle to the direction in which the feed is injected into the molten bath.

6. A method of claim 5, wherein the direction in which the oxidant is injected into the molten bath is about horizontal.

7. A method of claim 6, wherein the feed is injected into the molten bath in an upward direction.

8. A method of claim 5, wherein the direction in which the oxidant is injected into the molten bath is about vertical.

9. A method of claim 8, wherein the oxidant is injected into the molten bath in an upward direction.

10. A method of claim 8, wherein the oxidant is injected into the molten bath in a downward direction.

11. A method of claim 4, wherein the oxidant is injected into the molten bath in a direction which is about parallel to the direction in which the feed is injected into the molten bath.

12. A method of claim 11, wherein the oxidant and the feed are injected into the molten bath in an upward direction.

13. A method of claim 11, wherein the oxidant is injected into the molten bath in a downward direction.

14. A method of claim 13, wherein the feed is injected into the molten bath in an upward direction.

15. A method of claim 11, wherein the injection of the oxidant and of the feed is about coaxial.

16. A method of claim 11, wherein the feed includes a carbonaceous component and the atomic constituents include atomic carbon.
