Pyrolysis characteristics of bituminous coal

Pyrolysis characteristics of Shenmu bituminous coal and its pyrolysates were investigated in this paper. The results show that Shenmu bituminous coal is a kind of valuable resource. The semi-coke, tar and pyrolysis gas are useful material for industrial production. Friedman method was used to describe Shenmu bituminous coal pyrolysis. By using this model, the kinetic parameters were detemined based on TGA data. The pyrolysis process of bituminous coal involves the rupture of different types of chemical bonds with different energies.
