Abstract

Carbon monoxide is produced in an improved process in a carbon-filled, water-cooled generator in the configuration of a truncated cone in the longitudinal section, by the gasification of said carbon with a mixed gas of oxygen and carbon dioxide, wherein the improvement comprises injecting the mixed gas into the generator through at least one downwardly-directed, coolable nozzle arranged in the generator sidewall and removing the carbon monoxide formed.

Claims

1. In a process for the production of carbon monoxide in a carbon-filled, water-cooled generator in the configuration of a truncated cone in the longitudinal section, by the gasification of said carbon with a mixed gas of oxygen and carbon dioxide, wherein the improvement comprises injecting the mixed gas into the generator through at least one downwardly-directed, coolable nozzle arranged in the generator sidewall and removing the carbon monoxide formed in a direction opposite to the nozzle orientation at the side or head of the generator.

2. The process according to claim 1 wherein the carbon is in the form of coke.

3. The process according to claim 2 wherein additives are mixed with the coke for reducing the melting point of slag formed in the generator.

4. The process according to claim 1 wherein the volumetric ratio of oxygen to carbon dioxide in the mixed gas is down to 1:

1.

5. The process according to claim 4 wherein the ratio is in the range of 1.2:

1 to 1.3;

1.

6. The process according to claim 1 wherein oxygen is injected through an additional nozzle arranged above the mixed gas nozzle.

7. The process according to claim 1 wherein the nozzle is equipped with a double jacket supplied with water for cooling.

8. The process according to claim 7 wherein the nozzles are copper.

9. The process according to claim 1 wherein liquid slag is removed intermittently at the bottom of the generator.

10. The process according to claim 1 wherein liquid slag is removed continuously at the bottom of the generator.
