程序升温下不同煤含氮基团转化的显微红外研究
Micro Infrared Study on Transformation of Nitrogen Groups at Linear Heating Temperature
摘要
Abstract
The high temperature infrared microscope was used to test the rule of the functional groups of lignite,bitumite and anthracite at linear heating temperature,and the transformation rule of nitrogen-containing group,including O-H groups,aliphatic NH groups,nitrosyl,nitroso-group of aliphatic and aromatic was speculated.The results show that with the temperature increasing,the free O-H groups and hydrogen bonds association O-H molecule are appeared in lignite.When the temperature is higher than 500 ℃,nitrogen is separated in the form of aliphatic nitroso-group.In the bituminous coal at the linear heating temperature,there are free O-H groups and a large number of aromatic groups,but the hydrogen bonds association O-H molecule are weak.When the temperature is higher than 700 ℃,aliphatic nitroso-group increases,but other groups reduce.Due to the high coalification of anthracite,the difficulty of fracture and form of bonds in the combustion progress are quite,so the change trend of functional groups are the same.关键词
