The hydrogen to carbon (H/C) ratio of coal gasified gas in the range 0.2–1.0, far less than the desired value for the coal to methanol process. Therefore, a water gas shift unit is needed to raise the H/C ratio, which results in a great deal of CO2 emission and carbon resource waste. At the same time, there is 7 × 1010 m3 coke-oven gas (COG) produced in coke plants annually in China.
