Improved Sedimentation Performance of Low-Rank Coal by ...

11-02-2021  In this study, the sedimentation performance of a low-rank coal suspension was investigated by coprocessing with hard-to-treat saline wastewater from the coal chemical industry. The changes in the intensity of backscattering light (ΔBS) and transmission light (T) of the coal suspension with different saline wastewater dosages were analyzed by a Turbiscan Lab based on the multiple

All of these improvements contribute to enhanced Boudouard reactivity of the modified char and consequently improved power outputs of related cells. For example, the peak power density of a cell fueled with the modified char reaches 220 mW cm -2 at 850 °C, whereas that of a conventional coal char-fueled cell is 62 mW cm -2 .

Improving Process Performances in Coal Gasification

This paper is aimed at developing process alternatives of conventional coal gasification. A number of possibilities are presented, simulated, and discussed in order to improve the process performances, to avoid the use of pure oxygen, and to reduce the overall CO2 emissions. The different process configurations considered include both power production, by means of an integrated gasification ...
