EFFET OF POTASSIUM AND IT'S COMPOUND ON CATALYTIC GASSIFICATION OF COAL-BLACK LIQUOR SLURRY
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.
