摘要
Abstract
Simulation experiments of biomethane generation of the coal samples of low rank taken from Shaqu mine were carried out under condition of different pH, Eh, and the influence of pH, Eh on gas production of low rank coal was analyzed. The results of the experiments indicated that it was favourable to methane generation when pH is 7 and Eh is -225mV. The gas production was simulated under the best experimental conditions, obtaining that the maximum CBM biggest production of Shaqu coal was 13.799 mL/g; With the extension of reaction time, the concentration of methane increased gradually, while the concentration of nitrogen reduced gradually, and the concentration of carbon dioxide increased firstly and then decreased.关键词
