Abstract
Two types of nitrogen-containing artificial coals have been prepared using cellulose and model nitrogen compounds. Nitrogen functionality has been investigated by XPS and pyrolysis GC-NPD, and it does not change during artificial coalification. The major products of gas-phase nitrogen are HCN and NH_3 during pyrolysis of artificial coals with different nitrogen functionality at 800℃. It was found that quinoline-type N gives more formation of NH_3 than carbazole-type N.
