摘要：
The pyrolysis of mixtures of a bituminous coal with 30% by weight of iron oxides, heated gradually from 25 degree to 1000 degree C, at heating rates from 0. 2 to 15. 5 degree C/min was studied by thermogravimetry. Weight loss in the tar formation zone - due to the presence of iron oxides - was observed to decrease proportionally with the increase in the rate of heating. Weight loss in the coke at high temperatures - produced by the consumption of carbon in the reduction process - is higher for the low heating values. The tar yield is adversely affected by hematite, especially during initial additions.
