摘要

对黑液水煤浆(由造纸黑液(废液)和煤制成)、水煤浆进行了等温和不等温热重试验

发现在1 200℃下

黑液水煤浆焦的转化率较高

气化活性比水煤浆焦提高了68.8%;黑液水煤浆焦的霞石衍射峰值比水煤浆焦高出22.5%;通过计算得到黑液水煤浆焦的活化能为125.44 kJ/mol

反应级数约为0.5

添加催化剂碳酸钾后煤焦的活化能比没有添加的下降了近40%。

Abstract

The thermogravimetric test under constant temperature and non-constant temperature has been carried out for coal-black liquor slurry which is made up from waste water of paper mills and coal

and for the ordinary coal-water slurry.It is discovered that the conversion rate of coal-black liquor slurry is higher under temperature of 1200 ℃

the gassifying activity had enhanced 68.6% from that of the ordinary coal-water slurry.The nephelite diffraction peak value of coal-black liquor slurry was 22.5% higher than that of ordinary coal-water slurry.Through calculation

it is obtaned that activation energy of coal-black liquor slurry coke is 125.44 kJ/mol

reactive degree is about 0.5

after adding catalyst potassium carbonate

the activation energy of coal coke has decreased near 4% from that without adding catalyst.
