Coal fines are among the key issues that restrict the highly efficient production of coalbed methane (CBM) because they cause blockages in reservoirs and accidents in wellbores. Coal fines always agglomerate to migrate and plug flow paths in formation water. Therefore, an investigation of their agglomerate behaviour in deionized, standard saline and NaHCO3 suspensions was conducted on different rank...
Mercury species distribution in the flue gas from three typical coal-fired power plants have been investigated using a C-5000 sampler for Ontario Hydro Method (OHM) to evaluate specified Hg emission inventories in the largest coal-production province of China, Inner Mongolia. The feed coal, bottom ash, fly ash and gypsum have also been sampled in the field. Mercury emissions are in the dominant form...
A series of core–shell structured CuO–ZnO@H-ZSM-5 (CZ@H) catalysts were prepared by homogeneous precipitation through urea hydrolysis. This novel preparation procedure and excellent core–shell structure had contributed to its high-performance for CO hydrogenation under 260°C, 2.0MPa and high space velocity (6000mL/(g -cat h). The space time yield of dimethyl ether (DME) over CZ@H(7.5) reached...
