平朔煤的热解试验研究

对平朔煤在不同温度下进行了热解研究,考察了热解温度对煤热解产物产率和热解气性质的影响规律。研究表明,对上述煤样,随煤的热解温度升高,半焦产率下降,干馏气产率增加;液体率在一定温度范围内先增后降,在600℃左右达到最高。热解温度升高,热解气中H2的含量就越高,热解气中CH4的含量在热解温度550~650℃左右达到最高。随热解温度的升高,CO2的含量显著降低,烃类组分随温度升高是先升后降,峰值出现在600℃左右。 Has made the pyrolysis research of Ping suo coal under different temperature,inspected influence rule of the pyrolysis temperature in the production rate of the coal pyrolysis product and the property of pyrolysis ash.The research shows that about the above coal sample,the semi-coke production rate drops,and the dry distillation production rate increases,along with the coal pyrolysis temperature increases.The liquid rate increases then falls in certain temperature range,achieves high about 600℃.When the pyrolysis temperature is increasing,the H2 content of pyrolysis ash is higher,the the CH4 content achieve high about in 550～650℃ pyrolysis temperature.Along with the pyrolysis temperature ascents,the CO2 content reduces,the hydrocarbon compound component rises then falls along with the temperature increases,the peak value appears about in 600℃
