carbocoal
2.The law on component change of carbocoal from different temperature pyrolysis of Yanzhou bituminous coal in ordinary pressure fluidized bed in nitrogen atmosphere is analyzed, especial change law of sulfur, and activation energy of pyrolysis carbocoal in different temperature is analyzed in thermogravimetric analyzer, It is found that activation decreases with pyrolysis temperature increasing.
3.The result shows that the carbocoal produced by modified lignite under low temperature pyrolysis is a good raw material for preparing sulphonated coal; The quality of raw materials and the temperature are the most important factors affecting the products.
