摘　　要：目前煤炭气化技术作为清洁、高效利用煤炭的先进技术之一是我国能源领域的重要发展对象,煤的气化是利用气化剂将煤及其干馏产物最大限度的转变为煤气的过程。本文是利用热重分析法对褐煤进行非等温气化,研究褐煤在CO2气氛下的气化特性,并且进行了相应的分析。实验结果表明,在非等温条件下,通过FT-IR的分析得到不同热解温度的半焦物理化学结构的特点。At present, the coal gasification technology, as a clean and efficient use of coal, is an important development object in the energy field in china, the coal gasification is a process that change the coal and its pyrolysis products to gas by using the gasifying agent. Lignite was selected as the research object, through the coal into particles, and the non - isothermal methods use in the lignite, the gasification characteristics in CO2 atmosphere were studied, respectively. Under non - isothermal conditions, through FT - IR analysis, the physical and chemical characteristic of different pyrolysis temperatures was studied.
