Abstract:
 Experiments are carried out on Yangquan coal(a kind of arthracite)and Fengshuigou coal(a kind of lignite)
in a layer-flow bed reactor to study the characteristics of the main pyrolysis gases and the elements releasing performance
in the pyrolysis process at 800—1 200,℃. The gases,such as NH3,HCN,CH4,CO,C2H4 and C2H2,
release in the prophase and metaphase of the pyrolysis process,while H2 is released in the metaphase and anaphase.
Compared with Yangquan coal,HCN is released earlier and faster with greater concentration from Fengshuigou coal
than from Yangquan coal. The contents of vapor,oxygen element and hydrogen element in the pyrolysis gases are
higher than those in the primary coal. Of the pyrolysis gases,the majority of combustible component is hydrogen gas
in the case of Yangquan coal,while that is carbon oxygen in the case of Fengshuigou coal. As pryrolysis temperature
increases,the ratio of carbon to hydrogen decreases,the ratio of hydrogen to nitrogen increases,and the ratio of
carbon to oxygen decreases in the case of Fengshuigou coal but increases then decreases in the case of Yangquan coal.
