| 摘 要： | 以O2/水蒸气作为气化剂,对褐煤半焦气化过程进行实验研究.结果表明,随着气化温度的提高,在生成的煤气组成中CO和H2含量增加,而CO2和CH4的含量减少,煤气热值和合成气产率均增加;在温度一定时,随着氧气流量的增加,煤气中CO含量和H2含量先增加然后逐渐减少,CO2含量增加,CH4含量减少,煤气热值和合成气产率均存在一个最大值.

| Abstract: | In the test gasification of lignite semi-coke was investigated by using pure oxygen and steam.Results showed that CO and H2 content of gas,calorific value and yield of syngas increase with increasing gasification temperature.CO2 and CH4 content of gas reduce with increasing gasification temperature.At the same gasification temperature,with rise of pure oxygen flow,CO and H2 content of gas increase first and then reduce.CO2 content of gas increases and CH4 content of gas reduces.The calorific value and yield of syngas have a maximum value. |
