摘要
为了从化学层面上阐述煤炭自燃机理,选用苯乙醛、苯甲醚、二苯基甲烷、苯乙醚、苯甲醇、二苯基甲醇和α-苯丙醇作为煤自燃模型化合物,研究在常温至150℃的氧化反应.利用氧化反应装置和分析仪器,定量分析各种活性基团的化学反应动力学和热力学参数、氧化产物,从而推断出其活性大小的不同.结果表明,各模型化合物在常温至150℃之间,均消耗一定的氧气,同时CO、CO2也有不同程度的生成,其氧化特性与煤相似.
In order to elaborate the mechanism of coal spontaneous combustion at chemistry aspect,hyacinthin,anisole,diphenylmethane,phenetole,benzyl alcohol,benzhydrol and α-phenylpropanol were chosed as model compound of coal spontaneous combustion,then oxidation reaction of them were studied from normal temperature to 150 ℃.By means of oxidation device and analytical instrument,chemical reaction kinetic parameters,thermodynamic parameters and products of the active groups were quantitatively studied,and then the most active model compound was recognized.The results show that all the model compound consume oxygen and produce CO and CO2 at different degrees between normal temperature and 150 ℃,and oxidative characteristic of the model compound is similar to that of coal.
