The formation of N-containing products during char–steam gasification has been investigated in a laboratory scale fixed bed reactor. Experiments were conducted at 1000°C, 0.1–1.0MPa, and 6–46% of H 2 O in He base flow. Two very different coal chars, which were prepared from the rapid heating of Australian bituminous and sub-bituminous coals, were studied. The nitrogen-containing products released...
The chemistry of char-N release and conversion to nitrogen-containing products has been probed by studying its release and reactions with O 2 , CO 2 , and H 2 O. The experiments were performed in a fixed bed flow reactor at pressures of up to 1.0MPa. The results show that the major nitrogen-containing products observed depend on the reactant gas; with O 2 , NO, and...
To help in assessing coalbed methane resources, methane adsorption capacities of Permian coals from the Bowen Basin of Queensland were investigated and related to other coal properties. Maximum methane capacities of moisture-equilibrated coals, normalized to a pressure of 5 MPa and 30°C, showed a continuously increasing (and reasonably linear) trend with increasing rank over the range 80-92 wt% total...
