| Abstract: | The thermal pressurized dehydration method was applied to investigate the temperature,pressure and pressure keeping time affected to the dehydration upgrading of the lignite from Eji,Inner Mongolia and investigate the desulphurization results during the technique process.The experiment results showed that under the conditions of 160 OC,7 MPa and pressure keeping time of 30 seconds,the water content of the lignite could be reduced below 12 % and the dehydration rate of the water content could be reached over... |
