- (b) passing an inert gas across the sixth stage (bottom) of the vertical shaft and then across the first stage (top);
- (c) passing air across the fourth stage of the said shaft and then feeding the said air in part to the second stage and in part to the third stage of the said shaft;
- (d) separating the gas product of the second stage into oil and a producer gas;
- (e) feeding the gas product of the third stage through the fifth stage of the said shaft and then into a carbon monoxide separation unit;
- (f) using the inert gas produced in the carbon monoxide separation unit as feed to the sixth stage of the said shaft;
- (g) feeding the pure carbon monoxide product of the carbon monoxide separation unit to a Boudouard reactor;
- (h) reacting carbon monoxide to carbon dioxide and carbon;
- (i) separating the carbon from the carbon dioxide;
- (j) feeding the carbon dioxide to the third stage of the said shaft; and
- (k) discarding the treated solid from the bottom (sixth) stage of the said shaft.
