co气氛下褐煤加压快速热解过程中ch4的逸出规律
, PP. 641-649
Keywords: co气氛,加压,快速热解,ch4逸出规律,化学键断裂
Abstract:
？在管式反应器上进行了霍林河褐煤加压快速热解实验，研究了co气氛下ch4逸出规律。在加压快速热解条件下，由于co解离态吸附的o（a）吸附在煤上，提供了活性中心，电负性强的o（a）诱发其周围其他原子的电子云向o（a）偏移，减弱了原来化学键的强度，导致芳香环的开裂，侧链、醚键和脂肪链的断裂提供更多的自由基，稳定煤热解生成的碎片，促进了ch4的生成和逸出。因此，co气氛下ch4产率较n2气氛下的高，在900℃、1.0mpa时，50%co气氛下的ch4产率较n2气氛下的提高了12.5%，并且ch4产率随着温度升高、压力的增大而增大。
