<p>A process for the gasification of coal or other carbonaceous matter is disclosed, the process being characterized by scrubbing of HCN, NH3 and COS from the synthesis gas stream with an aqueous solution at 14, stripping of the aqueous solution to release the HCN, NH3 and COS at 20, and consumption of the HCN, NH3 and COS in the gasification step at 4. The gas stream may be cooled prior to scrubbing. Particulate matter may be removed from the gas stream before or during scrubbing. <IMAGE></p> |
