摘要

采用热重分析法对CO2气氛下不同煤种、不同升温速率、不同灰煤比对煤的热解气化动力学特性的影响进行了研究。结果表明

随着升温速率的增加

反应速率下降

反应的活化能增加;在相同的升温速率下

随着灰煤比的增加

灰中的金属氧化物起了催化作用

使反应速率增加

反应的活化能减小

在高温阶段尤为明显;随着煤变质程度的增加

反应速率降低。

Abstract

By using the thermogravimetric analysis method

the influence of different coal sorts

different temperature-rising rates

and different ash/coal ratios upon kinetics of coal pyrolysis and gasification in CO2 atmosphere has been studied.Results show that the reaction rate decreases and the activeation energy increases along with the temperature-rising rate increases;the metal oxide in ash acts as catalyst along with the ash/coal ratio increases under condition of same temperature-rising rate

making the reaction rate to increase

and being remarkable especially in high-temperature range

at the same time

the activation energy in reaction decreases;and the reaction rate decreases along with the metamorphic degree of coal increases.
