✦ Synopsis

stone covered with nickel, and heated to 3oo°C. When the temperature is below 3oo°C. and the content of carbon monoxide below 17 per cent. the carbon monoxide is changed quantitatively into methane. When the temperature is too high, carbon dioxide is formed, and when the content of carbon monoxide is too great, carbon is deposited. The first gas, rich in carbon monoxide, is used for fuel. The chief advantages are: (i) the poisonous carbon monoxide is removed, making the gas much safer; (2) the heat value is increased from 2800 to 8500 calories. The costs of the process are given.
