Coal gasification inevitably produces CO. How can we maximize the CO content, while minimizing the levels of other components with low or no calorific value, such as oxygen?
Correction: The useful gases in coal gasification are CO + H2. The key indicators for evaluating coal gasification processes are the carbon conversion rate and the cold gas efficiency. If the level of CO is high, then dry pulverized coal gasification should naturally be used. In this process, it is necessary to control the CO2 content; keeping the reaction temperature as low as possible is an effective measure for achieving this.

I’ve heard that there are processes utilizing coke gasification with pure oxygen, where CO2 is used as a cooling gas; in theory, this can produce the maximum amount of CO. But I’ve never seen the actual device.
