Learn from the advanced practices of the *Brothers section; there are prizes for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Brief answer: The effect of the oxygen-coal ratio on temperature, syngas composition, gas yield, cold gas efficiency, and carbon conversion rate. 1. As the oxygen-coal ratio increases, the gasification temperature keeps rising. 2. The CO content in the syngas first increases and then decreases, the CO2 content first decreases and then increases, the H2 content first increases and then decreases, while the CH4 content gradually decreases. 3. Gas production first increases and then decreases. 4. The efficiency of cold gas first increases and then decreases. 5. The carbon conversion rate increases.
The higher the oxygen-to-coal ratio, the greater the temperature, gas production, and carbon conversion rate.
