SULFUR DISTRIBUTION WITHIN COAL PYROLYSIS PRODUCTS

The pyrolysis of coal leads to distribution of sulfur compounds in pyr olysis gas, char and tar generated during the process. The effect of t he process parameters of autothermal coal pyrolysis in the circulating fluidized bed reactor on total sulfur distribution has been investiga ted. Several experimental tests were performed at the temperature of 9 20 degrees C. Non-coking coal from the Wieczorek Mine (Upper Siresian Coal Basin) and brown coal from the Belchatow Mine were examined for s ulfur distribution. It was found that distribution of total sulfur in coal pyrolysis products is basically affected by coal to air ratio and addition of steam or acceptor to the pyrolysis process.
