Abstract
The invention concerns a method for treatment of combustible gas produced from the waste liquor from alkaline cellulose processes, especially sulfate digestion, and which is suitable for energy production. In the method the alkali metal compounds of the combustible gas are brought into contact with one or more amphoteric oxides at high temperature. The mixed oxide compound formed during treatment can be separated from the gases by their low vaporizability, which leads to a significant reduction in the amount of alkali metal compounds in the gas. Hydrolysis of the mixed oxide compounds containing alkali metals separated from gases leads to formation of an active cooking chemical (alkali metal hydroxide), during which the amphoteric oxides in question are simultaneously regenerated.
